Tooth Colored Fillings
What is composite bonding?
- Tooth colored fillings, also known as composites, are materials that can be bonded (adhered) to teeth. This allows a smaller, more conservative filling then with dark metallic materials.
- Composite is made of microscopic particles of sand, ceramics and resins.
- Composite can match the shade, shape and wear of teeth better and more conservatively than other filling materials.
- Because of the strength of the bond, it can strengthen rather than weaken the tooth in which it is placed.
How is composite bonding done?
- All decay and old filling material is removed from the tooth.
- The tooth is treated with a mild acid that cleans and opens microscopic pores into the surface of the tooth. A watery thin layer of composite (a bonding agent) is painted onto the prepared tooth surface. This layer flows into the pores.
- A bluish bonding light sets the material.
- Layers of composite are added until the tooth is completely filled.
- The filling is adjusted to a proper fit and then polished.
