Tooth-Colored Fillings in Gangnam Seoul
Natural-looking composite fillings for cavities, chips and old metal fillings — usually completed in one visit.
In short: tooth-coloured fillings are made of composite resin, a mix of resin and fine glass particles that bonds to the tooth and is matched to its shade. They suit small to medium cavities, chips and replacing old metal fillings. Each filling typically takes 20–40 minutes in a single visit.

Understanding composite fillings
What are tooth-coloured fillings?
Composite resin is placed in thin layers, bonded to the tooth, hardened with a curing light, then shaped and polished to blend in.
Because composite bonds to the tooth, less healthy tooth often needs removing than with metal. Fillings are overseen by Dr. Hyo-Jin Lee, trained in conservative dentistry at SNU Dental Hospital.
When another option is better
Very large cavities may need a lab-made restoration.

Questions patients ask us
Tooth-coloured fillings FAQ
How long do tooth-coloured fillings last?
With good care, many years. It depends on size, position and habits such as grinding.
Can I replace old metal fillings?
Often, yes. Your dentist checks whether composite or an inlay/onlay is the better replacement.
How much do tooth-coloured fillings cost in Seoul?
Cost depends on your diagnosis, the materials and the number of teeth or visits involved. After your examination we give you a written, itemised quote in English before any treatment begins.
Are composite fillings strong enough for back teeth?
For most small and medium cavities, yes. Very large ones may need an inlay, onlay or crown.
Can I eat straight after?
The filling is hardened before you leave; just wait for the numbness to wear off.
