Cosmetic bonding is a procedure where tooth-colored composite resin (often called “white” or “plastic” filling material) is applied to a decayed, chipped, fractured, or discolored tooth.
The procedure get 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, cosmetically matching the neighboring teeth can be more challenging with bonding versus laboratory restorations.
