Five warning signs and three ways to check · Seongmo Dental Clinic, Sungshin Women’s University Station · Board-certified specialist in Integrated Dentistry
💡 The short answer. Overtreatment begins where a clinic states the number of treatments and the price without showing the evidence for the diagnosis. A plan that cannot explain, tooth by tooth, why with images and measurements is one to question. There are three ways to check: look at the radiographs and intraoral photographs yourself, ask why each tooth needs it, and ask for the urgent to be separated from what can wait. Showing these three first is a principle of practice at Seongmo Dental Clinic.

A large part of dental treatment is non-covered, so prices and criteria differ between clinics and the patient has no means of verifying that judgement. Add a structure in which advertising spend must be recovered through treatment fees, and the practice of bringing people in on an event price and then attaching other treatment. Overtreatment arises less from any particular clinic than from a structure in which the evidence need not be shown. So the focus of checking is not the clinic’s reputation but whether there is evidence.
First, ask to see the images. Decay appears as a dark shadow on radiographs and as discolouration and cavitation on an intraoral camera. Seongmo Dental Clinic shows early decay in colour with Q-ray fluorescence, and we look at the intraoral photographs together on the monitor. We do not treat decay that cannot be confirmed by eye.
Second, ask the reason tooth by tooth. If they can explain, one by one, why this tooth, why now and why this method, there is evidence.
Third, ask for priorities. A plan that cannot be divided into what must be done now, such as pain and infection, what can be done within a few months, and what can be watched, is a plan saying everything is urgent. The criteria for treatment order are set out in what order dental treatment should go in.
It is. If fear of overtreatment leads to not believing the diagnosis at all, necessary treatment is missed. Early decay can be watched, but decay that has reached the nerve becomes a root canal if left, and extraction if left longer. Confirming the evidence and refusing treatment are different things. What follows from delay is in what happens if you put off a root canal.
You can. Particularly for treatment that is hard to reverse and expensive — extraction, several implants, full orthodontics — having it confirmed once more elsewhere is the patient’s right. What to bring and how it works is set out in can I get a second opinion before an extraction.
Seongmo Dental Clinic has practised since 1998 on the principle of recommending only the treatment that is genuinely needed, based on data. We show you the condition with Q-ray, CBCT and an intraoral camera, and give a written treatment plan separating covered from non-covered items. 30 seconds on foot from Exit 2 of Sungshin Women’s University Station, 02-922-3966.
I was told I have several cavities — do they all need treating?
It depends on which are confirmed on images and how far they have progressed. Decay close to the nerve comes first while early decay can be watched and managed, so ask for the priorities to be separated out.
Does early decay have to be treated?
Early decay confined to enamel can often be stopped with fluoride and care, so it is frequently not drilled straight away. Seongmo Dental Clinic tracks whether it is progressing with Q-ray.
I was told to replace all my old gold restorations — is that right?
Old and problematic are not the same. Only those with marginal decay, fracture or gaps confirmed on images need replacing; sound prosthetics can stay.
Can I ask for a written treatment plan?
You can. Seongmo Dental Clinic provides a written plan separating covered and non-covered items without being asked.

Seongmo Dental Clinic opened in 1998. I have held this position as the third director since April 2022, and I have one standard for choosing equipment: if I would not use it on my own family, I do not use it on my patients. One more scanner must not mean more treatment. If anything, it should mean cutting less, extracting less and finishing in one visit, from a more accurate original. The goal is not to be first with new equipment, but to offer the better of what is possible today to the patient sitting in the chair.
