Composite bonding, also known as dental bonding or tooth bonding, is a cosmetic dental procedure in which a tooth-coloured resin material is applied to the surface of a tooth to improve its appearance. It is a popular and relatively simple procedure that can be done in a single visit to the dentist.
The composite resin material used in bonding is a mixture of plastic and glass that can be shaped and polished to match the natural colour and texture of the surrounding teeth. The dentist will first prepare the tooth by roughening the surface and applying a conditioning liquid to help the bonding material adhere to the tooth. Then, the composite resin is applied in layers and hardened with a special light, which bonds the material to the tooth.
