Bonding involves adhering composite resin material that is matched to the color of the tooth, to the front of the tooth. There are many reasons for undergoing a bonding procedure: 

• Repair damage done to the tooth by decay

• Alter the alignment of the tooth 

• Close gaps between the teeth 

• Simple cosmetic purposes.

​

First the surface of the tooth is roughened in order to accept the bonding and to hold it. A gel is applied to micro-etch the tooth surface, and a primer/bond agent is applied so the material adheres to the surface. Then the material itself is placed on the tooth and hardened with intense light. The composite resin material is shaped and polished to get a lustrous finish as a last step.
