Bonding is a treatment that can be used to repair teeth that are decayed, chipped, fractured or discoloured 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 an ultraviolet light or laser. 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.
