Dental bonding is the application of a tooth colored composite to improve the overall appearance of a discolored or chipped tooth. It also can be used to close spaces between teeth to make teeth look longer or to change the shape or color of teeth.
First the surface of the tooth is lightly roughened, and then a conditioning liquid is applied that help the bonding material stick to the tooth. The composite is then placed on the tooth in layers and the bonding agent hardens with intense light. Last step, the bond is polished to look exactly like a real tooth, or like the tooth it is repairing because the resin comes in many shades, the final layer can be matched perfectly to the patient’s tooth color. Bonding usually lasts several years before it needs to be repaired.
