Bonding is one of the tooth restoration procedures to repair a decayed, chipped, fractured or discolored tooth. Bonding can be shaped and polished to match the surrounding teeth. It is used for cosmetic dentistry purposes to improve the appearance of a discolored or chipped tooth. It is used to close spaces between teeth, make teeth life longer or change the shape or color of teeth.

Bonding can also be used as an alternative to amalgam fillings and protects a portion of the tooth's root that has been exposed when gums recede.
