Dental bonding is used to repair various types of tooth damage, such as cracks, gaps, and breaks. The procedure adheres a tooth-colored resin (durable plastic material) to the natural tooth. The resin is cured using a visible blue light that "bonds" the material to the tooth. The result is an improvement in the overall appearance of the teeth. Dental bonding is a relatively simple cosmetic dental procedure, that preserves the most amount of the tooth's enamel.
