Dental bonding is a very effective broken tooth repair treatment and which uses tooth-colored composite resin. After preparing the tooth surface, the resin is bonded onto the tooth and is shaped and polished to look natural. The material is hardened with ultraviolet light. Dental bonding is the same treatment that is sometimes used to correct crooked front teeth in cosmetic dentistry.
A small or medium-sized cavity in a tooth can be mended in a similar way using tooth-colored composite resin. The dentist first numbs the tooth and removes the decay and shapes the cavity before filling it with the resin, hardening it with ultraviolet light before the filling is shaped and polished.
