Bonding is the application of a tooth-colored composite resin to repair a decayed, chipped, fractured or discolored tooth, to make teeth appear longer, and as a cosmetic alternative to amalgam fillings.
The procedure is called bonding because the material bonds to the tooth.
Bonding is among the easiest and least expensive of cosmetic dental procedures. The composite resin used in bonding can be shaped and polished to match the surrounding teeth. Most often, bonding is used for cosmetic purposes to improve the appearance of a discolored or chipped tooth. It also can be used to close spaces between teeth, to make teeth look longer or to change the shape or color of teeth.
Patients should be aware of the limitations of bonding. It is a temporary solution and not a substitute to longer term solutions that can be achieved with ceramic veneers.
