Seongmo Dental Library · Since 1998
What You Heard at the Dentist,
What does it actually mean?
“They say I need root canal treatment — is it really necessary?”
“Does this tooth really have to be extracted?”
The questions we hear most often in our clinic, explained term by term are laid out in full here. We have gathered in one place the clinical standards Seongmo Dental has upheld since 1998, together with records verified directly by the press. It is never too late to decide once you understand the explanation.
Before You Decide on Treatment, Just Three Things to Check
The three statements below are the principles Seongmo Dental explains to every patient, in the same order.
1. First, check whether the tooth can be saved
Save first
Extraction cannot be undone. That is why it must be the last resort. We first check whether the tooth can be kept through root canal treatment, pulp preservation, or partial restoration, and only then decide.
Seongmo Standard — If you have been advised to have a tooth extracted, it is perfectly normal to seek a second opinion from another dentist.
2. Painful treatment gets postponed
Painless care
During the six months you put it off out of fear of pain, the tooth only gets worse. Reducing pain is not a matter of comfort — it is what makes timely treatment possible.
Seongmo Standard — We control the anesthetic injection speed mechanically to reduce numbness and pressure.
3. The less you grind away, the longer it lasts
Minimal intervention
A tooth does not grow back once it has been ground down. Prioritizing minimal or no reduction extends the life of the natural tooth.
Seongmo Standard — We first consider whether a partial restoration (inlay/onlay) can solve the problem instead of a crown.
Contents
Contents — Start by Understanding the Terms
We have organized this so you can look up the exact words you heard during your visit. Under each entry we have also noted the standards Seongmo Dental actually applies when making a judgment.
Symptoms · Conditions
Dental Caries (Cavities)
Dental caries
A disease in which acid produced by oral bacteria dissolves the hard layers of the tooth and creates a cavity. There is almost no pain in the early stages, and by the time it feels sensitive it has often already reached the inner layers.
Seongmo Standard — We do not immediately drill early caries; we monitor its progress and confirm whether it is advancing.
Pulpitis
Pulpitis
Inflammation of the pulp, where the nerve and blood vessels inside the tooth are gathered. If it is only sensitive to cold there is a chance of recovery, but throbbing at night and poor response to painkillers indicate a stage that is difficult to reverse.
Seongmo Standard — If the stage is still reversible, we first try methods that keep the nerve alive rather than removing it.
Periodontitis (Gum Disease)
Periodontitis
A state in which inflammation has descended into the bone that holds the gums and teeth in place. It begins with bleeding and swelling, and as it progresses the tooth becomes loose. Bone that has been lost does not recover on its own.
Seongmo Standard — Even when there is mobility, if bone remains the tooth can sometimes be maintained with periodontal treatment, so we do not extract immediately.
Cervical Abrasion
Cervical abrasion
A condition in which the neck of the tooth near the gum becomes notched. Hard brushing, grinding, and improper occlusion are causes, and it is especially sensitive to cold water.
Seongmo Standard — We look for the cause first. Filling it without addressing the cause means the same spot will wear away again.
Tooth Crack
Cracked tooth
If the tooth looks fine but there is a sharp pain only when chewing, we suspect a microcrack. It is easy to miss because it often does not show up on radiographs.
Seongmo Standard — We confirm the location of the crack with magnified vision and an occlusal examination, then determine the scope of treatment.
Impacted Wisdom Tooth
Impacted third molar
A wisdom tooth that has failed to erupt properly and remains buried in the gum or bone. Extraction is considered when the surrounding gum swells repeatedly or it causes decay in the tooth in front.
Seongmo Standard — After confirming the distance to the nerve canal on imaging, if there are no symptoms we do not rush to remove it.
Sensitive Teeth (Dentin Hypersensitivity)
Dentin hypersensitivity
A symptom in which exposed dentin causes momentary sensitivity to cold, sweet foods, or air. In many cases it is not caused by a cavity.
Seongmo Standard — We first determine whether the cause is decay, a crack, or gum recession, and then treat accordingly.
Treatments · Procedures
Root Canal Treatment (Endodontics)
Root canal treatment
Treatment in which the inflamed pulp is removed, the inner canals are disinfected and then filled, so that the tooth itself is preserved. It is the most representative way of avoiding extraction.
Seongmo Standard — Even if it means several visits, we do not rush to finish until disinfection is sufficient.
Root Canal Retreatment
Endodontic retreatment
The process of removing the existing filling material and treating again when inflammation recurs in a tooth that has previously had root canal treatment. It is more demanding than the initial treatment.
Seongmo Standard — We will also continue treating teeth that were treated at another dental clinic.
Pulp Preservation Treatment
Vital pulp therapy
Treatment in which, when decay has reached close to the nerve but the nerve is still alive, the nerve is covered with a protective material and kept alive instead of being removed entirely.
Seongmo Standard — Before moving straight to root canal treatment, we always review once whether there is room to save the nerve.
Tooth Extraction
Tooth extraction
A procedure to remove a tooth. It is chosen when pain and infection would recur even if the tooth were kept — for example when the root is split or most of the supporting bone is gone.
Seongmo Standard — Extraction is the last resort. We show you the imaging and explain together why the tooth cannot be saved.
Dental Implant
Dental implant
A method in which an artificial root is placed in the jawbone where a tooth is missing, and a tooth-shaped restoration is mounted on top. It has the advantage of not requiring the adjacent teeth to be ground down.
Seongmo Standard — If a natural tooth can be saved, that approach takes priority over an implant.
Crown · Inlay
Crown & Inlay
A crown covers the entire tooth, while an inlay or onlay fills only the damaged portion. Which is used is determined by how much tooth structure remains.
Seongmo Standard — Before covering the whole tooth, we first check whether a partial restoration will solve the problem.
Periodontal Treatment (Root Planing)
Scaling & root planing
Treatment that removes calculus and inflamed tissue attached to the root surface beneath the gum, creating an environment in which the gum can reattach.
Seongmo Standard — Because sore gums make this treatment easy to postpone, we divide anesthesia and recovery into separate stages.
Anesthesia · Pain
Painless Anesthesia
Computerized anesthesia
A method in which the speed and pressure of the anesthetic being delivered are kept constant by a machine. The aim is to reduce the pressure and stinging that occur when it is pushed in quickly.
Seongmo Standard — The more you have put off treatment out of fear of pain, the more we start slowly from this stage.
Local Anesthesia
Local anesthesia
Only the nerves around the area to be treated are temporarily blocked. You remain conscious, and sensation usually returns after two to three hours.
Seongmo Standard — We give separate instructions so that you do not bite your lip or cheek while the anesthesia is wearing off.
Managing Dental Anxiety
Dental anxiety care
It is common to postpone appointments simply out of fear of the dentist. Explaining the procedure in advance and agreeing on a stop signal greatly reduces anxiety.
Seongmo Standard — Raise your hand and we stop immediately. We make this promise before treatment begins.
Prevention · Care
Scaling
Scaling
A procedure to remove calculus that cannot be brushed away. Korean national health insurance covers one session per year for those aged 19 and over.
Seongmo Standard — For those with severe sensitivity, we adjust the intensity and sequence as we proceed.
Powder Scaling
Powder polishing
A method in which a fine powder is sprayed with water to remove staining and thin deposits from the tooth surface. There is less irritation from metal instruments touching the tooth.
Seongmo Standard — We recommend it to those sensitive to pain and cold, and to those concerned about staining.
Fluoride Application · Sealants
Fluoride & Sealant
Fluoride makes the tooth surface less soluble in acid, while sealants fill in the grooves of the molars in advance so that food does not become trapped. They are mainly applied to children and adolescents.
Seongmo Standard — Preventing decay before it forms costs far less than drilling after it appears.
Dental Floss · Interdental Brushes
Interdental cleaning
A toothbrush cannot clean between the teeth. Those gaps are exactly where cavities and gum disease most often begin.
Seongmo Standard — Depending on the condition of your gums, we select the right tool for you between floss and an interdental brush.
Equipment · Technology
Plasma Root Canal Treatment
Plasma endodontics
A method that applies plasma technology to the disinfection of the interior of the root canal. The aim is to help disinfect even narrow canals that instruments have difficulty reaching.
Seongmo Standard — Seongmo Dental has introduced and operates the plasma root canal device ‘Plagen’.
Digital Imaging Diagnostics
Digital X-ray & CT
Digital sensors reduce radiation exposure compared with film, and the images can be viewed together on screen while we explain.
Seongmo Standard — Rather than explaining in words alone, we have you see it for yourself before deciding on treatment.
Treatment Under Magnification
Magnification
Treating while viewing the tooth larger than the naked eye allows through loupes makes it possible to distinguish the boundary between what to keep and what to remove far more accurately.
Seongmo Standard — The prerequisite for minimal reduction is seeing accurately.

Digital · Same-day Restoration 23
Same-day Restoration
A digital prosthetic treatment method that completes everything from the intraoral scan to design, milling, and placement of the restoration in a single visit.
Instead of waiting for a dental laboratory to fabricate the restoration, inlays, onlays, and crowns are made the same day with in-house CAD/CAM equipment. Whether it can be applied depends on the condition of the tooth and the extent of the restoration.
Seongmo Dental operates same-day restoration treatment with a complete CEREC chairside workflow (Primescan · Primemill · SpeedFire) in-house.
Chairside CAD/CAM
A dental digital system that completes scanning, design, and milling in one place beside the treatment chair.
Because it does not go through an outside laboratory, fabrication time is shortened and precision can be managed based on the scan data.
CEREC
A representative chairside CAD/CAM system in which an intraoral scanner, milling machine, and sintering furnace work together to produce same-day ceramic restorations.
A system that has evolved since its first clinical application in 1985, capable of producing everything from inlays to crowns in-house.
PrimescanIntraoral Scanner
An intraoral scanner that captures the teeth and gums as high-resolution 3D data without rubber impression material.
There is less gagging during the impression process, and immediately after scanning you can review the condition of your teeth on screen while receiving an explanation.
PrimemillMilling Machine
Milling equipment that cuts ceramic and zirconia blocks exactly according to the design data to produce restorations.
SpeedFireSintering Furnace
A furnace that processes zirconia sintering and glazing in a short time, making chairside zirconia crown fabrication possible.
Digital Impression (Intraoral Scan)Digital Impression
The process of taking an impression of the tooth shape with an intraoral scanner instead of rubber impression material.
There is no error from impression material distortion, and the data is easy to store and transmit, making it the starting point of digital prosthetics.
CAD/CAMComputer-aided Design/Manufacturing
A fabrication method in which restorations are designed on a computer (CAD) and milled with dedicated equipment (CAM).
Dental CBCT Cone-Beam CT
Precision imaging equipment that confirms the position of teeth, jawbone, and nerve canals in three dimensions.
It is used for implant placement planning, diagnosis of impacted wisdom teeth, and understanding complex root canal anatomy.
Seongmo Dental operates an HDX Dentri 3D CBCT.
Guided Implant Surgery
An implant surgery method that combines CBCT and intraoral scan data to plan the placement position, depth, and angle in advance, and realizes that plan with a surgical guide device.
Intraoral Scanner
Equipment that photographs the mouth in 3D to take a digital impression
Impressions are taken quickly and precisely without the gagging of rubber impression material. Data is transmitted immediately, shortening the fabrication period as well.
3D Printer
Equipment that prints models, guides, and temporary teeth from digital designs
It precisely fabricates implant surgical guides, diagnostic models, and temporary restorations. It is one of the core pieces of equipment in digital dentistry.
Digital Occlusal Analysis
An examination that analyzes the distribution and sequence of biting force numerically
It analyzes even the intensity and timing of forces that articulating paper cannot show, making precise occlusal adjustment possible.
Dental Operating Microscope
Precision equipment that magnifies the treatment site more than 20 times
It finds fine root canals and cracks invisible to the naked eye, raising the success rate of precision procedures such as root canal retreatment and apical surgery.
Dental Laser
Equipment that uses light energy for soft-tissue excision, sterilization, and pain relief
In gum contouring and stomatitis treatment there is little bleeding and recovery is fast. Lasers of various wavelengths are used depending on the procedure.
Electronic Apex Locator
A device that precisely measures the length of the root canal electronically
During root canal treatment it accurately measures the length to the root tip, preventing over- or under-treatment. It also reduces the number of radiographs needed.
Intraoral Camera
A compact camera that photographs the inside of the mouth in high definition and displays it on a monitor
Patients can see the condition of their own teeth while receiving an explanation, which improves understanding and trust.
Digital Diagnostic Model
A 3D virtual dental model created from an intraoral scan
It is used for orthodontic and prosthetic planning and for before-and-after comparison. Unlike plaster models it is easy to store and compare, and more precise.
Wet Milling
A machining method that precisely mills ceramic restorations while spraying a coolant (water) on the material.
Depending on the material, milling is divided into wet milling (with water) and dry milling (without water). Glass ceramics such as e.max are usually milled wet, while zirconia is usually milled dry; having both capabilities in-house widens the range of restorations that can be fabricated on site.
Seongmo Dental has both wet and dry milling equipment in-house, and the doctor personally designs and fabricates everything from inlays to crowns and dentures.
AquaCare / Air Abrasion
A device that removes cavities and stains without a drill by spraying fine powder particles together with water.
Because it uses an air-abrasion (air-particle) method, it has none of the noise or vibration typical of a drill, and shallow cavities can sometimes be treated without anesthesia. AquaCare is a brand name for this type of device.
Seongmo Dental has introduced AquaCare and uses it for cavity removal and sensitivity treatment for patients with significant treatment anxiety.
Qray / QLF
A diagnostic device that shines a special light to detect early cavities and cracks through their fluorescence response.
Without using radiation, it marks areas with bacterial activity in red fluorescence, making it possible to check for early cavities, micro-cracks, and plaque that are hard to see on X-rays.
Seongmo Dental uses Qray diagnosis alongside other exams to distinguish whether a dark spot is a cavity or a stain before deciding on treatment.
Computer-controlled Anesthesia
A device in which a computer controls the injection speed and pressure of the anesthetic at a constant rate to reduce injection pain.
The main reason anesthetic injections hurt is not the needle but the pressure when the anesthetic is delivered too quickly. Computer-controlled syringes deliver it slowly and steadily instead. There are several brands, including i-JECT.
Seongmo Dental operates a step-by-step painless anesthesia system that includes topical anesthesia and a digital metered syringe.
Intraosseous Anesthesia / QuickSleeper
A method that delivers anesthetic directly inside the jawbone, achieving fast anesthesia with a small dose.
It takes effect faster than ordinary infiltration anesthesia and tends to leave less prolonged numbness in the lips and cheeks. QuickSleeper is a brand name for a computer-controlled device that implements this method.
Seongmo Dental uses QuickSleeper intraosseous anesthesia for cases such as treating lower molars that do not respond well to ordinary anesthesia.
Natural Tooth Preservation · Root Canal Treatment 22
Tooth Preservation
A clinical principle of establishing treatment plans in the direction of minimizing extraction and preserving the original tooth as much as possible.
Even as implant technology has advanced, it remains difficult to replace the sensation of the periodontal ligament that surrounds the tooth root. Teeth that can be saved are best maintained through root canal treatment and conservative restoration.
Root Canal Treatment
Treatment that removes infected or inflamed pulp, then disinfects and seals the root canal, preserving the tooth without extraction.
Several visits may be required, and after treatment the tooth is often protected with a crown or similar restoration.
Endodontic Retreatment
Treatment in which the existing filling material is removed and the procedure performed again when reinfection or symptoms occur at a previously treated root canal site.
Dental Pulp
The nerve and blood vessel tissue at the center of the tooth, which supplies nutrition to the tooth and is responsible for sensation.
Pulpitis
A state in which the pulp has become inflamed due to decay or a crack. Depending on how far it has progressed, it is divided into a recoverable stage and a stage requiring root canal treatment.
Rubber Dam
A thin rubber sheet that exposes only the tooth being treated and isolates the rest, blocking contamination by saliva and contributing to quality control in root canal treatment.
Ni-Ti Rotary File
A root canal shaping instrument made of highly elastic nickel-titanium alloy, capable of shaping even curved canals along their natural form.
Root Canal Obturation
The final stage of root canal treatment, in which the disinfected interior of the canal is filled completely with a dedicated material to prevent reinfection.
MTAMineral Trioxide Aggregate
A highly biocompatible dental cement used for pulp protection, perforation repair, and root-end retrofilling.
Cracked Tooth Syndrome
A condition in which a microscopic crack that is difficult to detect visually causes momentary pain on chewing.
If it progresses it can lead to root canal treatment or extraction, so early diagnosis is important.
Reversible Pulpitis
Mild nerve inflammation that can recover once the stimulus is removed
It is characterized by brief sensitivity to cold that disappears as soon as the stimulus is gone. At this stage the nerve can be saved by removing the cause, such as treating the cavity.
Irreversible Pulpitis
A state in which the nerve is irreversibly damaged and root canal treatment is required
It is characterized by pain that persists even without stimulation, or that worsens at night. At this stage, root canal treatment is the only way to save the tooth.
Pulp Necrosis
A state in which the tooth nerve has died completely and sensation is lost
It is easy to mistake the disappearance of pain for healing, but the dead nerve tissue becomes a breeding ground for bacteria and progresses to inflammation at the root tip. Root canal treatment is essential.
Periapical Lesion
An inflammatory lesion that forms at the tip of the tooth root
If a dead nerve is left untreated, an abscess, granuloma, or cyst forms at the root tip. It is found as a dark shadow at the root tip on X-ray and is treated with root canal treatment or apical surgery.
Periapical Abscess
A state in which pus collects at the root tip, causing swelling and pain
It hurts on biting and the gum, or even the face, may swell. Drainage and root canal treatment are required, and severe swelling or fever calls for emergency care.
Root Canal Irrigation & ShapingRoot Canal Irrigation & Shaping
The stage of root canal treatment in which the inside of the canal is washed with disinfectant and shaped
Fine instruments (files) widen the canal while disinfectant solution washes out bacteria. This is the most important stage, determining the success or failure of root canal treatment.
Apicoectomy
Treatment that surgically removes the inflamed area at the root tip directly
When endodontic retreatment does not resolve the problem, the gum is opened and about 3 mm of the root tip is removed together with the lesion. It is the last means of saving the tooth before extraction.
Pulpotomy
Treatment that removes only the upper portion of the infected nerve while preserving the nerve in the root
It is performed mainly on primary teeth or on children’s permanent teeth whose roots are not yet fully formed. A major advantage is that root growth can continue to be guided.
Post & CorePost & Core
A reinforcing post placed inside a tooth weakened after root canal treatment
A root-canal-treated tooth loses its moisture supply and fractures easily, so when little tooth structure remains a post is placed and a crown is fitted for reinforcement.
Instrument (File) Fracture
A state in which a root canal instrument has broken and remained inside the canal
A rare complication that occurs in thin, curved canals. Depending on the location, we choose the best option among removal, bypass treatment, or observation.
Biomimetic Dentistry
A treatment concept that mimics the structure and properties of natural enamel and dentin to restore teeth while removing as little tooth structure as possible.
It reproduces the two-layer structure of a natural tooth — hard on the outside, resilient on the inside — using materials, aiming to bond-restore only the damaged portion instead of covering the whole tooth with a crown. The goal is to reduce the amount of tooth removed and the risk of nerve damage.
Seongmo Dental selects overlays or bonded restorations over crowns whenever possible, in line with biomimetic principles.
Plasma-assisted Root Canal Disinfection
A root canal treatment method that uses low-temperature plasma to assist in disinfecting the inside of the root canal.
It aims to raise the success rate of root canal treatment by helping disinfect even thin lateral canals that instruments cannot reach. Plasgen is a brand name for this type of equipment, and it is sometimes considered as a last option before extraction during retreatment.
Seongmo Dental combines plasma equipment with retreatment to increase the chances of preserving the natural tooth.
Prosthetics · Restoration 24
Crown
A restoration that covers an extensively damaged tooth entirely to restore its shape and function.
Inlay / Onlay
A partial restoration in which a restoration fabricated to match the tooth shape is bonded after decay removal. When it also covers the cusps of the chewing surface it is called an onlay.
Endocrown
A one-piece restoration that uses the pulp chamber space of a root-canal-treated tooth as its retentive structure.
Because it requires no separate post and reduces the amount of remaining tooth that must be cut, it becomes an option for molars that meet the conditions.
Zirconia
A high-strength dental ceramic, widely used for molar crowns that bear heavy chewing forces.
e.maxLithium Disilicate
A lithium disilicate glass ceramic with good translucency, often used for inlays and anterior restorations.
Hybrid Ceramic
A CAD/CAM material combining the properties of ceramic and resin. Its moderate elasticity places relatively little burden on the opposing teeth.
Composite Resin Restoration
A caries treatment method in which tooth-colored composite resin is placed directly and cured with light (photopolymerization).
Provisional Restoration
A temporary restoration fitted to protect the tooth and maintain chewing function until the final restoration is completed.
Occlusal Adjustment
The process of finely adjusting how the upper and lower teeth meet after a new restoration is fitted, to create a comfortable occlusion.
Dental Bridge
A fixed restoration fabricated by connecting to the teeth on either side of the missing tooth, using them as supports.
Zirconia Crown
A ceramic crown with high strength and a natural color
It withstands molar chewing forces without metal and is currently the most widely used crown material. There is no gum discoloration and its aesthetics are excellent.
e.max Crown
A glass ceramic crown with outstanding translucency
It reproduces the translucency of natural teeth best, making it suitable for aesthetic anterior restorations. Its strength is lower than zirconia, so the material is chosen according to the location.
PFM CrownPorcelain-Fused-to-Metal Crown
A crown made by fusing porcelain over metal
Once the standard material, it is increasingly being replaced by zirconia because of limitations such as a visible metal margin at the gum line and porcelain chipping.
Temporary / Provisional CrownTemporary/Provisional Crown
A temporary restoration worn until the final restoration is completed
It protects the prepared tooth and temporarily restores appearance and function. Because the adhesive is weak, avoid sticky or hard foods.
Complete Denture
A denture supported by the entire gum ridge when no teeth remain
It is retained by suction against the gums, so an adaptation period is needed. If retention is insufficient, an overdenture using two to four implants can improve it dramatically.
Removable Partial Denture
A removable prosthesis that clasps onto the remaining teeth
It uses the remaining teeth to restore several missing teeth at once. Maintaining the health of the supporting teeth is important for the life of the denture.
Denture Rebase
A repair in which the inner surface of a loosened denture is refilled with new material for a proper fit
The jawbone continues to resorb over the years, so dentures become loose. Rather than making a new one, the inner surface is refitted to restore close adaptation.
Shade Selection
The process of matching the restoration’s color to the surrounding teeth
Measurements are taken under natural light using dedicated shade guides, photographs, and digital devices. For anterior restorations, sharing color information with the dental technician is especially important.
Crown Margin
The boundary line where the restoration meets the natural tooth
If this margin is not precise, bacteria penetrate through the gap and secondary caries develops. It is the key factor determining the quality of a restoration.
Pontic
The artificial tooth portion of a bridge that fills the space of the missing tooth
It is fabricated to rest on the gum, and dedicated floss such as Superfloss is needed to clean its underside.
Overlay
A partial restoration that covers the entire chewing surface of a molar while preserving as much of the tooth’s side walls as possible.
It is an intermediate treatment that covers more than an inlay but removes less tooth structure than a crown. Choosing an overlay instead of a crown for a cracked molar or a large cavity can preserve more healthy tooth structure.
Seongmo Dental follows the principle of first assessing whether an overlay can resolve the problem before recommending a crown.
everX Flow
A reinforced composite resin containing short glass fibers, used as a restorative material that substitutes for dentin.
It has higher crack resistance (fracture toughness) than ordinary resin, so it is used as a core material to fill the inner layer of severely damaged teeth. It is a GC brand name and is used as a dentin-replacement layer in biomimetic restorations.
Adhesive Bonding
Refers to the process of chemically bonding a restoration firmly to the tooth.
Even with the same restoration, the bonding process determines its lifespan. Zirconia requires surface treatment with an MDP primer, and glass ceramics require a ceramic primer (such as Monobond) to prevent them from coming loose. If a restoration keeps coming off, the bonding step should be checked.
Seongmo Dental reduces bonding failures by using material-specific adhesive systems and rubber dam isolation.
Cervical Abrasion / Abfraction
A condition in which the neck area where the tooth meets the gum becomes notched, causing sensitivity and a visible groove.
It results from habits such as brushing too hard side to side and clenching, which concentrate force at the neck of the tooth. Sensitivity is common, and the notched area is filled with resin to stop progression. Because this area tends to lose fillings repeatedly, dedicated materials and careful bonding management are important.
Dental Implant 22
Dental Implant
Treatment that restores function by placing an artificial root in the site of a missing tooth and connecting a restoration on top of it.
Fixture
The body of the implant placed inside the jawbone, serving as an artificial tooth root.
Abutment
The post component that connects the fixture and the restoration (crown).
Osseointegration
The process by which the placed fixture bonds firmly with the surrounding bone; it usually requires a healing period of several months.
Bone Graft
Surgery that augments bone volume with graft material when the alveolar bone is insufficient, creating the conditions for implant placement.
Sinus Lift
Surgery that lifts the maxillary sinus membrane in the upper molar region and augments the bone, securing the height needed to place an implant.
Peri-implantitis
Inflammation of the gum and bone around an implant; prevention through regular check-ups and hygiene management is important.
Immediate Implant Placement
A method of placing the implant in the same site on the day the tooth is extracted, chosen when conditions such as bone quality are suitable.
Healing Abutment
A temporary post that shapes the gum before the final restoration
It guides the gum to heal into a natural shape. The metal post that appears to protrude is this component, and it is replaced at the time of the final restoration.
Immediate Implant Placement
A method of placing the implant at the same time as extraction
When conditions are right, it can reduce the number of surgeries and the total treatment period. If infection or bone loss is severe, it is safer to wait for healing after extraction before placing.
Immediate Loading
A method in which a temporary tooth is connected on the day of placement
It is possible when initial stability is sufficient, and is useful in aesthetically important areas such as the front teeth. Hard foods should be avoided until osseointegration is complete.
Dynamic Navigation Implant Surgery
A digital implant procedure that places the fixture precisely at the position planned from CT and intraoral scans
A 3D surgical guide is fabricated so the implant is placed exactly at the planned position, angle, and depth. Minimizing the incision means less swelling and pain.
Surgical Guide
A 3D-printed device that helps place the implant at the planned position
Shaped as a template that fits over the teeth, it physically guides the drill direction and depth. It makes flapless or minimally invasive surgery possible.
Guided Bone Regeneration (GBR)Guided Bone Regeneration
A technique that induces bone regeneration using a barrier membrane and graft material
Graft material is placed where bone is lacking and covered with a barrier membrane so that bone cells, rather than gum tissue, grow in. It is performed simultaneously with the implant or in advance.
Sinus Lift
Surgery that raises the sinus membrane and fills in bone to secure bone height in the upper molars
In the upper molar region, bone height is often insufficient because of the maxillary sinus. Depending on the deficiency, it is performed by a vertical approach through the implant osteotomy or by a lateral approach.
Socket Preservation
A procedure that places graft material immediately after extraction to prevent bone resorption in advance
After extraction, bone can lose 30–50% of its width within a year. If an implant is planned later, it is advantageous to have this done at the time of extraction.
All-on-4
A method in which four implants support all the teeth of one jaw
Implants are placed strategically in areas with good bone to minimize bone grafting, and temporary teeth can even be fitted the same day. It is a representative treatment option for edentulous patients.
Implant Maintenance
Regular check-ups and cleaning that prevent inflammation around the implant
Implants have weaker defenses against inflammation than natural teeth, so professional care every three to six months is essential. Screw loosening and occlusal changes are checked at the same time.
Osstem
One of the most widely used implant manufacturer brand names in Korea.
In implants, the brand refers to the manufacturer that made the root (fixture). Treatment outcomes depend as much on diagnosis, placement position, and follow-up care as on the brand.
Straumann
The brand name of a Swiss implant manufacturer with a long global clinical track record.
A great deal of research has accumulated on its surface treatment and materials. The patient’s bone condition and the surgical plan have a greater effect on outcomes than differences between brands.
Dentium
One of the domestic Korean implant manufacturer brand names.
Along with Osstem, it is one of the most widely used brands in Korea. You can confirm which brand is used and whether genuine-product warranty applies during your consultation.
Inferior Alveolar Nerve Canal
The pathway of the sensory nerve (inferior alveolar nerve) that runs through the lower jawbone.
The distance to this nerve is critical to safety during lower molar implant placement or wisdom tooth extraction. Damage can cause abnormal sensation in the lip or chin, so it is standard practice to confirm its location with a 3D CT scan before surgery and maintain a safe distance.
Gum Care · Prevention 20
Scaling
A basic gum care treatment that removes calculus and plaque with ultrasonic instruments; national health insurance covers one session per year.
Dental Plaque
A sticky bacterial film that forms on the tooth surface; it is the starting point of caries and gum disease.
Calculus (Tartar)Calculus
Plaque that has calcified and hardened; it cannot be removed by brushing, so scaling is required.
Gingivitis
Early inflammation confined to the gums; it is a stage that can recover with scaling and consistent care.
Periodontitis
A disease in which inflammation has progressed to the alveolar bone and the tissues supporting the tooth are destroyed; it is the leading cause of tooth loss in adults.
EMS AirflowGuided Biofilm Therapy
Professional oral care equipment that sprays fine powder and water to gently remove biofilm and staining.
Seongmo Dental operates a gum care program using EMS Airflow equipment.
Periodontal Pocket
A gap between the tooth and gum that has become abnormally deep due to inflammation
A depth of 4 mm or more suggests periodontitis. The deeper it becomes, the less a toothbrush can reach and the more bacteria multiply, so it is managed with deep scaling (root planing) or gum surgery.
Gingival Recession
The phenomenon in which the gum recedes and the tooth root becomes exposed
Periodontitis, rough brushing, and clenching are causes. Sensitivity and the risk of root caries increase, and in severe cases a gum graft can cover the exposed area.
Periodontal Abscess
An acute infection in which pus collects within the gum tissue, causing swelling and pain
The gum swells outward and is severely painful when pressed. It is treated with drainage, cleaning of the causative area, and antibiotics if needed; left untreated, bone destruction accelerates.
Chronic Periodontitis
The most common form of periodontitis, progressing slowly over many years
Because it progresses with almost no pain, it is called a ‘silent disease’. By the time patients come in with loose teeth it has often already advanced considerably, so regular check-ups are the only way to detect it early.
Alveolar Bone Resorption
The phenomenon in which the bone supporting the tooth dissolves and diminishes
It is both a consequence of periodontitis and a natural change that occurs after extraction. If an implant is planned, it is advantageous to be seen before the bone resorbs further.
Root Planing
Treatment that removes deep calculus beneath the gum and smooths the root surface
Gum treatment that addresses areas deeper than scaling, usually performed under anesthesia, divided by region. It is the standard treatment for moderate periodontitis.
Periodontal Curettage
Gum treatment that scrapes away inflamed tissue from inside the gum
It is often performed together with root planing, removing infected soft tissue inside deep periodontal pockets to help the gum reattach to the tooth.
Supportive Periodontal Therapy (SPT)Supportive Periodontal Therapy
A regular care program to prevent recurrence after periodontal treatment
Periodontitis is a disease where the concept of ‘management’ matters more than cure. Regular cleaning and check-ups every three to six months determine the lifespan of your teeth.
Dental Floss
A thread-shaped hygiene tool for cleaning between the teeth
A toothbrush cleans only 60% of the tooth surface. To prevent interproximal caries and gingivitis, using floss at least once a day is recommended.
Interdental Brush
A small brush for cleaning wider gaps between the teeth
It is an essential tool for those with gum recession or with orthodontic appliances, implants, or bridges. Choosing the size that matches the gap is important.
Oral Irrigator (Water Flosser)Oral Irrigator
A device that cleans between the teeth and along the gum line with a jet of water
It is an effective auxiliary tool for care around orthodontic appliances and implants. Ideally it should be used alongside floss rather than as a replacement for it.
Regular Check-up IntervalRegular Checkup Interval
The interval between dental visits based on individual risk
Generally six months is recommended, or three to four months for those at high risk of periodontal disease or caries. Visiting when you have no symptoms is what real prevention means.
White Spot Lesion
A condition in which white, opaque patches appear on the tooth surface.
Causes include early-stage cavities (demineralization), enamel formation defects, and insufficient hygiene around orthodontic appliances. In early stages, improvement can be attempted without removing tooth structure, using resin-infiltration methods such as ICON or remineralization treatment.
Fluoride Varnish
A preventive treatment that applies high-concentration fluoride to the tooth surface to strengthen enamel.
It helps remineralize early cavities and is also used to relieve sensitivity. It is applied regularly not only to children but also to adults at high risk of cavities, and there are several products, including MI Varnish.
Aesthetic · General Care 25
Laminate Veneer
An aesthetic treatment that minimally prepares the surface of the front teeth and bonds thin ceramic to improve their shape and color.
Teeth Whitening
A procedure that brightens the shade by breaking down pigment inside the tooth with peroxide-based agents; temporary sensitivity may occur.
Dentin Hypersensitivity
A symptom of brief, sharp pain in response to cold stimuli due to exposed dentin and other causes; treatment differs depending on the cause.
Wisdom Tooth Extraction
A procedure to remove a third molar that is causing or likely to cause problems. Difficulty varies with the degree of impaction, so CBCT diagnosis is used.
In-office Whitening
Whitening performed at the dental clinic with high-concentration agents and light
Rapid color change can be achieved in one to three visits. It is performed safely with gum protection, and the effect lasts longer when combined with home whitening.
Home (Take-home) Whitening
Whitening done at home with a custom tray and low-concentration agent
Worn for a set time each day, the teeth gradually brighten over two to four weeks. Combining it with in-office whitening gives good lasting results.
Black Triangle
A dark triangular space created when the gum between teeth recedes
It occurs due to gum recession after periodontal disease or orthodontic treatment. It can be improved with composite resin filling or by adjusting the width of the proximal surfaces.
Digital Smile Design (DSD)Digital Smile Design
A digital system that designs the smile in advance using photographs and 3D data
You can see the expected result visually before treatment and refine the design in discussion with the clinical team. It greatly increases the predictability of aesthetic treatment.
Smile Mock-up
A process of experiencing the finished appearance in advance using temporary materials before treatment
Temporary material is applied to the areas planned for veneers or crowns so the shape can be checked in advance. It is adjusted until you are satisfied, and then reflected in the actual treatment.
Temporomandibular Disorder (TMD)Temporomandibular Disorder
Pain, sounds, and limited movement in the jaw joint and surrounding muscles
Typical symptoms include sounds when opening the mouth, pain, and difficulty opening wide. Most cases improve with non-surgical treatment such as splints, physical therapy, and medication.
Conscious Sedation
A sedation method that creates a comfortably relaxed state while consciousness and breathing are maintained
Unlike general anesthesia, you breathe on your own and can respond to the clinical team’s instructions. Because memory of the procedure is hazy, it is useful for patients with dental phobia.
Bruxism / Clenching
The habit of unconsciously grinding or clenching the teeth during sleep
It causes tooth wear and fracture, jaw joint pain, and headaches. Wearing a night guard (oral appliance) and Botox treatment can protect the teeth and joints.
No-prep Veneer
A laminate veneer method that attaches thin ceramic to the tooth with little to no tooth reduction.
The goal is to preserve the original tooth structure by minimizing removal. However, depending on tooth alignment, thickness, and protrusion, it can be difficult to apply in some cases, and forcing its use can make the restoration look thick, so careful diagnosis beforehand is important.
Seongmo Dental does not decide in advance whether a case is no-prep; we diagnose the tooth condition first and explain based on the minimum reduction actually needed.
Minish
A specific brand name widely used to refer to minimal-reduction laminate veneer treatments.
It is not an official dental term but a brand name. In general terms, it corresponds to minimal-reduction or no-prep veneers (laminates); regardless of the name used, the amount of tooth reduction, the bonding process, and the type of ceramic determine the essence of the treatment.
Zeronate
A brand name for a no-prep veneer line that markets itself as achieving ‘zero reduction.’
Like Minish, it is a brand name, and the general term is no-prep veneer. Even with different brand names, it is more accurate to compare the actual treatment by diagnosis, amount of reduction, and the ceramic/bonding method used.
Lumineers
The brand name of an extremely thin no-prep veneer developed in the United States.
It is known for attaching ceramic as thin as 0.3–0.5mm without tooth reduction. Whether it can be applied depends on the tooth’s color and alignment.
Ceraminate
One of the brand names used for laminate-type cosmetic restorations.
It is a coined term combining ‘ceramic’ and ‘laminate,’ and the material or fabrication method can differ slightly depending on the brand. We recommend consulting based on the amount of reduction, material, and indications rather than the brand name.
Composite Veneer
A treatment that improves the shape and color of teeth by directly building up dental resin on the tooth surface instead of ceramic.
It can be completed in a single visit and is relatively lower in cost, but compared to ceramic it is more prone to discoloration and wear, so it requires periodic maintenance.
Cosmetic Tooth Reshaping
A general, everyday term for treatments that improve the shape, alignment, and color of teeth using laminates, crowns, and similar methods.
It is not a formal diagnostic term, so the actual treatment is divided into laminate veneers, all-ceramic crowns, resin, orthodontics, and so on depending on the tooth condition. Which method is appropriate can be decided after checking both the amount of reduction and the bite together.
Gingivoplasty
A procedure that reshapes the gumline to improve issues such as teeth looking short or the gumline looking uneven from side to side.
It is applied to a ‘gummy smile,’ where a lot of gum shows when smiling, or to gumline asymmetry. Cases are divided into those where only the gum is reshaped and those where the underlying gum bone is also adjusted (crown lengthening).
Gum Depigmentation
A procedure that removes melanin pigment deposited in the gums to improve dark, reddish-black gum color.
A laser or chemical agent is used to remove the pigmented surface layer. Depending on the cause, such as smoking or genetics, the pigmentation may return over time.
Diastema
Refers to a gap between the upper front teeth.
Causes include a prominent labial frenum (the muscle band inside the lip), mismatched tooth size, and tongue-thrusting habits. Depending on the size of the gap and its cause, treatment may involve resin, laminate veneers, or orthodontics.
Tetracycline Staining
A condition in which teeth are discolored in grayish-brown bands due to antibiotics taken during childhood.
Because the discoloration originates inside the tooth, ordinary whitening alone often has limited effect. Depending on severity, whitening, laminate veneers, or crowns are considered in stages.
All-ceramic
A general term for restorations made entirely of ceramic with no metal.
Zirconia and e.max (lithium disilicate) are representative examples. Because no metal shows through, they can achieve a translucency similar to a natural tooth.
Smile Line
Refers to the line formed between the edge of the upper front teeth and the curve of the lower lip when smiling.
It serves as a reference line when planning cosmetic front-tooth treatments such as laminate veneers or orthodontics, and Digital Smile Design (DSD) also analyzes this line first.
Pediatric Dentistry 10
First Dental Visit
Recommended within six months of the first tooth erupting, and no later than around the first birthday
The purpose is to build preventive habits before problems arise. A positive experience in early childhood shapes lifelong attitudes toward the dentist.
Primary Tooth Caries
Decay that develops in a child’s baby teeth
Primary teeth have thin enamel, so decay progresses very quickly. They are not ‘teeth that will fall out anyway’ — they directly affect the health of the permanent teeth, jaw development, and speech, so they must be treated.
Baby Bottle Tooth Decay
Early childhood caries caused by the habit of falling asleep with a bottle
It characteristically causes extensive decay starting from the upper front teeth. Prevention involves weaning off the bottle around the first birthday and wiping the teeth with gauze or an infant toothbrush after feeding.
Space Maintainer
A device that preserves the space where a primary tooth was lost early
If the adjacent teeth tip into the empty space, there is no room for the permanent tooth to erupt and malocclusion results. The space is maintained until the permanent tooth erupts, preventing this.
Premature Loss of Primary Teeth
Losing a primary tooth earlier than its natural replacement time
Caries and trauma are the main causes, and if left untreated, problems with permanent tooth alignment arise. When early loss occurs, it is necessary to check whether a space maintainer is needed.
Thumb Sucking Habit
An early childhood habit that creates malocclusion if it continues for a long period
If it continues past the age of three or four, it becomes a cause of protruding front teeth and open bite. It is improved with habit-breaking appliances or behavioral guidance.
Mouth Breathing
The habit of breathing through the mouth instead of the nose
It is associated with a lengthened face, a narrow jaw, gum inflammation, and increased caries risk. Along with treating causes such as rhinitis, early orthodontic intervention may be necessary.
MIH Molar Incisor Hypomineralization
A condition in which the enamel of the first molars forms poorly
The six-year molars are characteristically yellowish, crumble easily, and are sensitive. Early detection and protection with sealants or crowns is important.
Permanent Tooth Eruption Sequence
The general timing and order in which permanent teeth erupt
Starting with the first molars and lower front teeth at age six, the teeth are replaced in sequence until around age twelve. If a tooth is more than six months behind its symmetrical counterpart, it should be checked.
Pediatric Dental Trauma First Aid
What to do when a child’s tooth is broken or knocked out
If a permanent tooth has been knocked out, place it in milk and come in immediately; primary teeth are not replanted. Please bring any fragments as well.
Orthodontics · TMJ 24
Clear Aligner
Orthodontic treatment that moves the teeth by replacing clear removable appliances stage by stage
It is inconspicuous and allows free eating and brushing. It must be worn more than 20 hours a day to move as planned — wearing time determines success or failure.
Lingual Orthodontics
Orthodontics in which the appliance is bonded to the inner surface of the teeth so it is not visible from outside
Its aesthetics are the best, but an adaptation period for speech is needed and the cost is higher. It is chosen by those whose occupation makes visible appliances difficult.
Orthodontic Mini-screw (TAD)
A small screw placed in the jawbone to serve as anchorage for orthodontic force
It is an anchorage device that efficiently moves only the intended teeth. It is placed simply under local anesthesia and removed after treatment, and the site heals naturally.
Class I / II / III MalocclusionClass I/II/III Malocclusion
Classification of malocclusion based on the relationship of the upper and lower molars
In Class I the molar relationship is normal; in Class II the lower jaw sits back (a receding-chin tendency); in Class III the lower jaw sits forward (a protruding-chin tendency). Treatment strategy differs by classification.
Anterior Crossbite
A state in which the lower front teeth bite in front of the upper front teeth
If detected during the growth period, the likelihood of improvement with growth-modification appliances increases. Skeletal crossbite in adults may require orthodontics combined with jaw surgery.
Open Bite
A state in which the front teeth do not touch and remain open even when the molars are closed
Tongue thrusting and prolonged thumb sucking can be causes. It makes biting food with the front teeth difficult and can affect speech.
Orthodontic Retainer
An appliance that holds the teeth so they do not move back after orthodontic treatment
It is the final and longest stage of orthodontic treatment. It is worn all day at first and then at night, and neglecting it can cause relapse.
Orthodontic Relapse
The phenomenon in which teeth return to their original positions after orthodontic treatment
Neglecting to wear the retainer is by far the biggest cause. Mild relapse can be retreated relatively simply with partial orthodontics or clear aligners.
Orthognathic Surgery
Treatment that surgically corrects skeletal problems that cannot be resolved by orthodontics alone
It is combined with orthodontics in cases such as severe mandibular protrusion or facial asymmetry. Both function and aesthetics improve substantially.
TMJ Clicking / PoppingTMJ Clicking/Popping
Clicking or grating sounds when opening and closing the mouth
Displacement of the disc is a common cause. If there is only sound without pain or limited opening we observe it, but treatment is needed when pain accompanies it.
Invisalign
The brand name of a clear aligner system from Align Technology in the United States, widely known as a representative clear-aligner brand.
The general term is clear aligner. Appliance material and design software differ by brand, but treatment outcomes depend far more on diagnosis and treatment planning than on the appliance itself.
Incognito
The brand name of a custom-fabricated lingual orthodontic appliance attached to the inner (tongue-side) surface of the teeth.
It is one of the lingual-orthodontics brands where the appliance is invisible from the outside, with brackets custom-made for each patient. The general term is lingual orthodontics.
Clippy-C
The brand name of a self-ligating bracket made of tooth-colored ceramic material.
Because it is a self-ligating system that secures the wire with a bracket clip instead of rubber ligatures, it has less friction and is relatively easier to keep clean.
Damon Bracket
One of the representative brand names for self-ligating brackets.
It is a self-ligating appliance in the same category as Clippy-C, available in both metal and translucent (clear) versions.
Self-ligating Bracket
An orthodontic appliance that secures the wire with a clip (door) built into the bracket instead of rubber ligatures.
Reduced friction allows smoother tooth movement, and there is no concern about rubber ligatures staining. Damon and Clippy-C are brand names for this type of system.
Ceramic Bracket
An orthodontic method that is less noticeable because it uses tooth-colored ceramic brackets.
The treatment principle is the same as metal braces; only the color of the appliance differs. It is considered for patients who want a more discreet appearance but are not candidates for clear aligners.
Minor Tooth Movement
A limited-scope orthodontic treatment that moves only some teeth, such as the front teeth.
It has a short duration and lower cost, but it cannot be used when the molar bite also needs to be changed. Whether it is possible is judged by looking at the entire bite.
Aligner Attachment
A small, tooth-colored resin bump attached to the tooth surface during clear aligner treatment.
It acts as a handle that lets the clear aligner grip and move the tooth efficiently. It is cleanly removed once orthodontic treatment is finished.
Interproximal Reduction
A process of very slightly reducing the side surfaces of teeth to create the space needed for orthodontic movement.
It is typically performed within the enamel, at about 0.2–0.5mm per tooth, and is frequently used in clear aligner treatment.
Extraction Orthodontics
Orthodontic treatment performed after removing some teeth (usually premolars) when there is not enough space to align the teeth.
It is considered in cases of severe protrusion or significant lack of space. Whether to extract is decided after analyzing the facial profile and the bite.
Orthodontic Elastics
Small rubber bands hooked onto the upper and lower teeth to correct the bite.
Because this is an appliance the patient wears themselves, wear time has a direct effect on the length of treatment.
Adult Orthodontics
Orthodontic treatment performed on adults who have finished growing.
There is no age limit, but gum condition is important, so it is carried out alongside periodontal care. Less noticeable appliances such as clear aligners or lingual braces are often chosen.
Occlusal Splint
A custom-made oral appliance, usually worn at night, to reduce strain on the jaw joint and chewing muscles.
It is the most basic conservative treatment for TMJ disorder and bruxism. Unlike over-the-counter mouthguards, it is custom-made based on a measured bite and requires periodic adjustment while in use.
Seongmo Dental prioritizes conservative treatments such as splints, physical therapy, and Botox when treating TMJ disorders.
TMJ Disc Displacement
A condition in which the disc inside the jaw joint has shifted out of its normal position.
Symptoms include a clicking or catching sensation when opening the mouth, and in severe cases, difficulty opening the mouth fully. It is classified as reducing (the disc returns to position) or non-reducing (it does not), and treatment such as appliances or exercise therapy differs by stage.
Oral Medicine 8
Recurrent Aphthous Stomatitis
Round white ulcers that form repeatedly inside the mouth
It is closely related to stress, fatigue, and nutritional deficiency. Ointments and lasers can reduce the pain, and when it recurs frequently we recommend evaluating systemic factors.
Oral Candidiasis
An infection in which fungal overgrowth produces a white film inside the mouth
It is common with reduced immunity, long-term denture wear, or use of inhaled steroids. It is treated with antifungal agents, and denture hygiene is key to preventing recurrence.
Leukoplakia
A white patch–type mucosal lesion that does not rub off when scraped
Because it may be a precancerous lesion, confirmation by biopsy may be necessary. Smoking is the main risk factor, so quitting comes first.
Oral Cancer
A malignant tumor arising on the tongue, gums, cheek mucosa, and similar sites
Ulcers, lumps, and white or red lesions that do not heal for more than two to three weeks are warning signs. Early detection greatly improves survival, so regular check-ups are important.
Xerostomia (Dry Mouth)
A symptom in which saliva production decreases and the mouth becomes dry
Medication side effects are the most common cause, and it increases the risk of caries, bad breath, and stomatitis. Along with evaluating the cause, artificial saliva and salivation-promoting treatment are used together.
Burning Mouth Syndrome
Chronic pain in which the mouth burns without any obvious lesion
It is common in middle-aged women and is classified as neuropathic pain. Even though everything looks normal, it is a genuine pain disorder requiring a specialist approach.
Medication-Related Osteonecrosis of the Jaw (MRONJ)Medication-Related Osteonecrosis of the Jaw
A complication in which the jawbone becomes necrotic in patients taking osteoporosis or anticancer medication
There is a risk when extraction or implant placement is performed while taking bisphosphonates and similar drugs. Please always tell us the medications you are taking before a procedure; if necessary we will plan in consultation with your prescribing physician.
Halitosis (Bad Breath)Halitosis
An unpleasant odor coming from the mouth
80–90% of causes are in the mouth, with tongue coating, periodontal disease, caries, and dry mouth being the main culprits. Most cases improve with a tongue cleaner and periodontal treatment.
Insurance · Cost Guide 8
Insurance-covered Treatment
Treatment covered by national health insurance, reducing the patient’s share of the cost
Basic caries treatment, root canal treatment, extraction, periodontal treatment, and one scaling per year are included. The patient’s share is 30% at clinic level.
Non-covered (Out-of-pocket) Treatment
Treatment not covered by national health insurance, for which the patient pays the full amount
Implants (under age 65), orthodontics, whitening, veneers, and some prosthetics fall under this. Non-covered prices at each clinic are disclosed and published as a legal requirement.
Implant National Health Insurance
Implant insurance covering up to two implants per person for those aged 65 and over
With a patient share of 30%, the burden is greatly reduced. There are conditions — complete edentulism is excluded, for example — which we confirm during consultation.
Denture National Health Insurance
Denture insurance applicable once every seven years for those aged 65 and over
Both complete and partial dentures can be made with a 30% patient share. Remaking within seven years requires a qualifying exception.
Pediatric Composite Resin Insurance Coverage
Insurance coverage for resin treatment of permanent-tooth caries in children aged 12 and under
Light-cured composite resin treatment of permanent teeth in children aged 12 and under is covered by national health insurance. Please note that primary teeth are not covered.
Sealant National Health Insurance
Insurance coverage for sealing the grooves of the molars in those aged 18 and under
It applies to caries-free first and second molars, and at a 10% patient share it is very inexpensive. It offers the best cost-to-prevention value of any treatment.
Non-covered Fee Disclosure
A system requiring each clinic to publish its non-covered prices
Medical institutions are obliged to post the prices of non-covered items in the clinic and on their website. You have the right to receive a full explanation of costs before treatment.
Second Opinion
Seeking another doctor’s opinion on a diagnosis or treatment plan
Hearing another clinic’s opinion before expensive or extensive treatment is a patient’s natural right. You may request your records (X-rays and so on).

Frequently Asked
The Most Frequently Asked Six Questions
Does root canal treatment kill the tooth?
Because the nerve tissue inside the tooth is removed, sensation disappears, but the tooth itself remains and continues to function for chewing. Unlike extraction, it is treatment that preserves the root, and after treatment we also plan a protective restoration to prevent fracture.
Another dentist told me it should be pulled — can it be saved?
The judgment depends on how much tooth structure remains, how much supporting bone is left, and whether the root is split. Even looking at the same images, opinions can differ, so if you have been advised to have a tooth extracted it is perfectly normal to check once more. We look at the imaging together and explain why the tooth can or cannot be saved.
Will you continue treating a tooth that another dental clinic started?
Yes, we can. Teeth in the middle of root canal treatment, teeth with temporary fillings, and prosthetics placed long ago are all continued after we check their current condition. Rather than evaluating previous treatment, we focus on explaining what is needed from now on.
I am putting it off because I am afraid of the anesthetic injection.
Often it is the pressure of the fluid being pushed in, rather than the needle itself, that feels uncomfortable. Keeping the injection speed and pressure of the anesthetic constant by machine reduces that burden. We agree on a stop signal before we begin, and if you raise your hand we stop immediately.
How often should I have scaling done?
Generally an interval of six months to a year is recommended, and national health insurance covers one session per year for those aged 19 and over. If you have gum disease or smoke, a shorter interval may be necessary.
Can I know the treatment cost in advance?
After the examination we first explain the necessary treatment items and their costs, and then proceed. We distinguish between items covered by national health insurance and non-covered items, and we also discuss ways of dividing the treatment sequence to manage the burden.
