When older dental work starts to cause trouble
Pyeongchon is one of the planned new towns built around Seoul in the early 1990s, and many residents have looked after their teeth at local clinics for decades. Dental work, however, does not last forever. Crowns placed fifteen years ago may now leak at the edges. A root-canal-treated tooth can become sore again. An implant that felt fine for years may develop bleeding gums around it.
When that happens, patients often want a fresh look before agreeing to major treatment. Seoul E&D Dental Clinic in Sanbon-dong offers careful second opinions and, where needed, retreatment of existing work.
How do I reach the clinic from Pyeongchon?
Pyeongchon Station is on Line 4. Head south toward Oido, ride a few stops through Beomgye and Geumjeong, and get off at Sanbon Station. The clinic is about a 5-minute walk away, on the second floor of the Hanaro Building, 693 Gosan-ro, Sanbon-dong, Gunpo-si.

What does a second opinion at E&D Dental involve?
- Your history. Tell us what was recommended elsewhere and why. Bring any X-rays, CT files or written treatment plans you have.
- A fresh examination. We examine the teeth and gums ourselves and, where useful, take low-dose 3D CBCT images and use the Q-ray intraoral camera to look for cracks and decay under existing restorations.
- A clear explanation. We tell you what we see, whether we agree with the earlier plan, and what alternatives exist, including leaving something alone for now.
- Your decision. There is no obligation to have treatment with us. Our aim is that you leave understanding your situation.
This reflects a core principle at the clinic: explaining why treatment is needed and whether it truly must be done now. Read about it on our philosophy page.
Retreating root canals before choosing extraction
A tooth that has had a root canal can become reinfected years later, often because of a missed canal, a leaking crown or a new crack. Extraction is not the only answer. Root canal retreatment removes the old filling material, cleans the canals again with UC ONE ultrasonic irrigation, and reseals them. If retreatment from the crown side is not possible, root-end surgery may be an option. We will also tell you honestly when a tooth cannot reasonably be saved.
Implants that are not doing well
Implants need care just like natural teeth. Bleeding, swelling or bone loss around an implant, known as peri-implantitis, can threaten it. Our implant repair and retreatment addresses loose screws, broken crowns and infection. Ongoing implant maintenance helps prevent problems from returning.
Replacing tired crowns and fillings
Old metal or porcelain-fused crowns can be replaced with zirconia crowns, which are strong and tooth-coloured. Where several teeth have worn down or the bite has collapsed, a planned full-mouth reconstruction may restore function more predictably than repairing teeth one at a time.
Gums and supporting bone
Long-standing gum disease can quietly erode bone. Gum and bone regeneration procedures aim to rebuild some of that support around natural teeth or implants, depending on the defect.
Is it always worth redoing old work?
Not necessarily. An old crown with a slightly dark margin but a sound seal, or an amalgam filling with no decay beneath it, may be better left in place. Replacing a restoration always removes some tooth structure, so we only recommend it when there is a real problem: decay, leakage, fracture, poor fit or symptoms. We will show you on screen what we found so the decision is based on evidence you can see.
For international residents in Pyeongchon
If earlier dental work was done in another country, bring whatever records you have. We can help arrange English communication; please ask when booking.
