Bonding is a process in which tooth-colored filling material (composite resin) is applied to a tooth surface, sculpted to an ideal shape, hardened, and then polished for an ideal smile. Bonding can be used to fill in gaps and change the shape or color of your teeth. When teeth are chipped or slightly decayed, bonded composite resin may be the material of choice. Bonding is typically a one visit procedure and should last many years. Bonding is generally not as permanent a process as veneers, and can be vulnerable to the same kind of staining your natural teeth are prone to. Bonding can also be more prone to chips and cracks than veneers, caps, or crowns These services are generally preferred over bonding when such a procedure isn't deemed to be effective in the long run.
