Composite bonding is a cosmetic dental procedure that involves applying a tooth-colored resin material to the teeth to improve their appearance. The resin material is bonded to the tooth using a special light, and it can be used to repair decayed, chipped, or cracked teeth, as well as to close gaps between teeth and improve the appearance of discolored teeth. The bonding process involves roughening the surface of the tooth, applying a conditioning liquid, and then applying the resin material, which is molded and smoothed to the desired shape. Bonded teeth require special care to avoid chipping, and the durability of the bonding material depends on several factors, such as oral habits and the number of teeth treated. Composite bonding is a good option for small cosmetic changes, short-term correction of cosmetic problems, and correcting teeth in areas of low bite pressure. It is generally said to last between three and ten years before needing to be touched up or replaced.
