Teeth bonding is a dental procedure in which a tooth-colored composite resin is applied to the surface of a tooth to improve its appearance or to protect the tooth from damage. Bonding is often used to repair chips or cracks in the teeth, to close gaps between the teeth, or to change the shape or color of the teeth. Bonding can also be used to protect the tooth’s root if it is exposed due to gum recession. Bonding is typically a quick and painless procedure, and the composite resin can be matched to the color of the surrounding teeth.
