Dental bonding is a cosmetic dental procedure in which a tooth-colored resin material is applied to a tooth and then hardened with a special light, bonding the material to the tooth. The procedure is often used to repair teeth that are chipped, cracked, or discolored, or to close gaps between teeth.
During the procedure, the tooth surface is first prepared by roughening it and applying a conditioning liquid. Then, the resin material is applied to the tooth and molded into the desired shape. After the material is in place, a special light is used to harden it, bonding it to the tooth.
Dental bonding is a relatively quick and painless procedure that can usually be completed in one visit to the dentist. It is a less expensive alternative to other cosmetic dental procedures such as veneers or crowns. However, bonding may not be as durable as other options and may need to be replaced after several years.
