Cosmetic bonding is a procedure where tooth colored composite resin (often called "white" or "plastic" filling material) is applied to a decayed, chipped, fractures, or discolored tooth. The procedure gets its name because the resin bonds to the tooth. Unlike veneers, which are manufactured at a dental laboratory, bonding cases can be completed in a single visit. Cosmetic bonding is more fragile than a laboratory fabricated restoration such as a veneer or ceramic crown. Additionally, cosmetic matching the neighboring teeth can be more challenging with bonding versus laboratory restorations.
