Bonding is a process in which a plastic material called composite resin is applied to a tooth`s cleaned surface, sculpted to an ideal shape, hardened, and then polished. The procedure usually can be accomplished in a single visit.

Bonding is often performed in order to fill in small gaps between teeth, to change the color of  teeth or to fill in areas caused by tooth decay. Bonding can last for several years depending on several issues -a patient's home hygiene and diet, the area where the bonding is placed and if it has solid support of the underlying tooth, and if the patient is a grinder or not. In addition, to assure success, the bonding procedure requires a very clean and dry environment when it is placed. For this reason, several factors should be weighed to determine if composite is the correct material for a given application.

Bonding is more susceptible to staining or chipping than some other forms of restorations such as porcelain crowns or veneers, but it is less expensive. When teeth have small chips or are slightly decayed, bonded composite resins may be the material of choice. When fractures are large, decay is significant, or the area to be repaired can't be kept clean and dry, composites are not a good choice.
