Composite Fillings and Bondings

Composite resins are tooth-colored, plastic materials (made of glass and resin) that are used both as fillings and to repair defects in the teeth. Because they are tooth-colored, it is difficult to distinguish them from natural teeth. Composites are often used on the front teeth where a natural appearance is important. They can be used on the back teeth as well depending on the location and extent of the tooth decay.

Less tooth structure is removed when we prepare the tooth, resulting in a smaller filling than that of a silver amalgam filling.  Composites are bonded, or adhesively held in your tooth, making a more conservative repair.  This bonding also helps to strengthen a tooth that has been weakened by decay

Why does my filling need replacement?

Constant pressure from chewing, grinding or clenching can cause dental fillings, or restorations, to wear away, chip or crack. Although you may not be able to tell that your filling is wearing down, we can identify weaknesses in your restorations during a regular check-up.

If the seal between the tooth enamel and the restoration breaks down, food particles and decay-causing bacteria can work their way under the restoration. You then run the risk of developing additional decay in that tooth. Decay that is left untreated can progress to infect the dental pulp and may cause an abscess requiring root canal treatment.

If the restoration is large or the recurrent decay is extensive, there may not be enough tooth structure remaining to support a replacement filling. In these cases, the filling may need to be replaced with a crown.
