Bonding is done to repair damage done to the tooth by decay, to alter the alignment of the tooth, to close gaps between the teeth, or for cosmetic purposes. The procedure involves adhering tooth colored composite resin material to the front of the tooth. First, the surface of the tooth is roughened in order to accept the bonding and hold it. Then, a gel is applied to etch the tooth surface and a primer/bonding agent is applied so the material adheres to the surface. Next, the material itself is placed on the tooth and hardened with intense light. As a last step, the composite resin material is shaped and polished to get a lustrous finish.
