Dental bonding is a procedure in which a tooth-colored resin is applied and hardened with a special light, ultimately "bonding" the material to the tooth to improve a person's smile.
Bonding is a treatment that can be used to repair teeth that are decayed, chipped, fractured, or discolored or to reduce gaps between teeth. For this procedure, a dentist mixes composite resin — a type of plastic — into a paste, then tints the mixture to whiten or match the color of your teeth. Several layers of resin are applied to each tooth. Each layer is hardened under ultraviolet light or laser. The final steps include shaping and polishing the resin material so the finished tooth looks natural and smooth.
Bonding can also be used to build up older teeth to make them appear younger. Bonding is an option for people of all ages, including children, as the resin can be replaced as teeth grow.
