Bonding is a procedure that uses a tooth-colored composite resin (plastic) to repair a tooth. Bonding can be used on teeth that are decayed, chipped, broken or discolored. The procedure is called bonding because the material bonds to the tooth. Unlike veneers, bonding can be done in a single visit. Veneers are another way to repair some teeth. They are made in a laboratory and require a customized mold to achieve a proper fit.
Bonding is one of the easiest and least costly cosmetic dental treatments. The resin used in bonding can be shaped and polished to match the other teeth. Most often, bonding is used to make a discolored or chipped tooth look better. It also can be used to close spaces between teeth, to make teeth look longer, or to change the shape or color of teeth.
Sometimes, bonding also is used to protect a portion of the tooth's root that has been exposed when gums recede.
