You tried a self-whitening device, but it wasn't quite what you hoped.
Now with up to 2,200mW/cm²
of professional light output.
Seongmo Dental Clinic uses the Osstem Beautis Light whitening lamp. Whitening-gel reaction speed is directly proportional to light intensity — unlike an estimated 50–100mW/cm² for a typical self-whitening necklace device, this delivers up to 2,200mW/cm² at the optimal 430–490nm wavelength to accelerate the reaction.

Whitening results come not from willpower but from light intensity and wavelength.This is exactly where home devices hit their limit.
Professional whitening —
how is it different from self-whitening?
Professional whitening uses a high-concentration gel together with gum protection, accelerated by a high-output lamp. Seongmo Dental Clinic uses the Osstem Beautis Light, with up to 2,200mW/cm² output.
Many patients have tried a popular self-whitening product on the market but didn't see the results they expected — a limitation built into any home product that isn't medical-grade equipment.
Seongmo Dental Clinic offers professional whitening that goes beyond that limit. Whitening isn't a coating applied to teeth — it's a chemical reaction that breaks down stain pigment, so how efficiently that reaction is driven determines the result.

Why do output and wavelength
change the result?
Uniform across front teeth
The reason results differ even with the same gel comes down to conditions: whether surface stain was cleared first, whether the gel was applied evenly, and whether light reached every surface at sufficient, uniform intensity.
Seongmo Dental Clinic first removes surface stain with EMS AIRFLOW® powder cleaning before whitening. Following this order reduces the number of sessions needed, and the VITA Easyshade® V spectrophotometer confirms shade change as a number.
Whitening Sequence
We check for cavities, cracks, and gum condition, and record your current shade with the VITA Easyshade® V.
AIRFLOW® cleaning removes surface stain first to improve whitening efficiency.
The gums are protected, gel is applied, and the light is activated.
Shade is re-measured to confirm the change, and a home-care plan is provided if needed.Whitening isn't a procedure done by feel —
it's a treatment we measure and compare.
High-output or low-sensitivity —
which suits you?
Sensitivity & schedule considered
The most common whitening failure is pushing too hard and stopping due to sensitivity. Considering target shade, schedule, and tooth sensitivity together raises the odds of completing the plan.
For example, with a fixed deadline like a wedding or interview, we go with an intensive high-output approach; for a patient with exposed root surfaces from gum recession, we use the low-sensitivity approach spread over more sessions.
When a Consultation Is Needed First
Whitening gel can irritate these, so we treat them first.
Artificial material doesn't whiten, so a color mismatch with natural teeth can result. We discuss Primemill restoration timing and order together.
Drug-induced staining has a limited response, so we consider alternatives like veneers alongside it.The approach you can actually finish
is the most effective one.
Does whitening cause sensitivity?
It's manageable
Desensitizing care combined
As the whitening gel diffuses into the tooth, the nerve can become temporarily more sensitive — more so on teeth with exposed roots from gum recession or with micro-cracks.
Seongmo Dental Clinic first checks for cracks and early decay with Q-ray and, if needed, spreads treatment over multiple sessions with the low-sensitivity approach. After whitening, we advise on staining foods and care.
Post-Whitening Care
Please avoid strongly colored foods and drinks like coffee, black tea, wine, and curry where possible.
This varies with lifestyle and diet; regular cleaning and home care can extend how long results last.

- Glossary
- Professional Whitening
- Whitening performed at a dental clinic using a high-concentration gel and light-curing lamp.
- Whitening Lamp
- mW/cm²
- A device that irradiates a specific wavelength of light to accelerate the whitening gel's chemical reaction.
- mW/cm² (Irradiance)
- A unit of light output per unit area; a higher value means stronger irradiation.

FAQ
Is there really a difference from a self-whitening device?
Whitening reaction speed is proportional to light intensity. A home necklace-type device is estimated at around 50–100mW/cm², while Seongmo Dental Clinic's professional equipment is engineered for up to 2,200mW/cm² at the optimal whitening wavelength, giving a different level of reaction efficiency.
Does whitening damage the teeth?
Whitening gel doesn't cut or coat the tooth — it breaks down pigment. However, cavities or cracks can be irritated, so we diagnose and treat those first if needed.
How many sessions do I need?
This depends on your current shade, your target, and tooth sensitivity. At diagnosis, we measure shade and estimate the number of sessions, adjusting as we go.
How long does the whitening effect last?
This varies significantly by diet, smoking, and care habits. Regular AIRFLOW® cleaning combined with home care helps extend how long results last.
Do restorations or composite resin whiten too?
No — artificial material doesn't whiten. As natural teeth lighten, a color difference can appear, so it's best to plan restoration replacement timing and order together.
What does whitening cost?Whitening is a non-covered item and cost varies by method and number of sessions. You can check our fee guide, and we'll provide exact pricing after diagnosis.
