The term bonding is used in dentistry to describe permanently attaching dental materials to your teeth using dental adhesives and a high intensity curing light.
Whether you realize it or not, you’ve probably received a dental treatment involving either form of dental bonding: direct composite bonding or adhesive bonding of a restoration (filling crown, bridge, porcelain veneer, inlay/onlay) that was created in a laboratory or in-office.
Adhesive bonding refers to attaching a restoration to a tooth using an etchant, a bonding agent, an adhesive and a high intensity curing light. This method is typically used for esthetic and metal-free filling crowns, porcelain veneers, bridges and inlays/onlays.
