A tooth repair is a treatment to restore the function and integrity of the tooth. The type of procedure performed depends on the location and extent of the damage done. If the tooth enamel is chipped off, it is repaired with a filling. For a front tooth, bonding is used to place a tooth-colored composite resin by etching the tooth's surface with a gel to roughen it. This makes it easier for the bonding material to adhere to it. Next, adhesive material is applied to the tooth followed by a tooth colored resin. After shaping the bonding material to look like a natural tooth, an ultraviolet light is used to harden the material.
