Bonding
If a tooth is damaged, bonding can be an effective option to repair it. One of the
advantages of bonding is the versatility of the material. The following case
example demonstrates some of the steps when a tooth is bonded back together.

Evaluation
Factors when considering bonding include:
1. Amount and strength of remaining tooth structure. The greater the damage and the weaker
the remaining tooth structure, the less bonding is an optimal choice.
2. Any nerve exposure. If there is nerve exposure, treatment of the exposed nerve would be
the proper first step before restoring.

Step 1.
The tooth is sanded gently to give the damaged area a gritty texture. A special gel call an
etchant is coated on the teeth for 30 seconds, washed off, then dried. The purpose of this is
to improve the adhesion of the bonding materials to the tooth.

Step 2.
A material called the bonding agent is applied to the tooth. The bonding agent
acts as the glue, or the go-between, between the restorative material to the tooth.
A special light is shined on the bonding agent to set it from a liquid to a solid.

Step 3.
Composite is used to build up the damaged tooth, and adheres to the thin bonding
agent layer. The light is used to convert the composite from a putty-like to a
hardened material.

Step 4.
Finishing and Polishing. The material is sculpted into shape, then smoothed
and polished.

Completion.
The tooth has been successfully repaired. In this case the patient can return to
normal activity, but is advised to try to adjust habits, such as minimizing biting
on the bond. Although it can withstand biting and chewing, the less wear and
tear it is subject to, the longer it can last.
