Composite bonding refers to the use of composite resin material to restore teeth that are chipped, discolored, or misaligned. Composite resin material is always chemically “bonded” to the tooth whether it is used to restore front or back teeth. However, the popular term “bonding” typically refers to composite resin used for front teeth.
How does composite bonding work?
A tooth is prepared for composite bonding by lightly etching the surface and applying an adhesive liquid. Once the liquid sets, composite resin is applied and sculpted into the desired shape. The resin is then trimmed, smoothed, and polished for a natural appearance.
Longevity of Composite Bonding
The bonding procedure can often be completed in a single office visit and can significantly improve the appearance of a tooth. However, since the plastic resin used is not as strong as your natural tooth enamel, it is more likely to stain, chip, or break than natural teeth. Bonding typically lasts three to five years before need of repair.
