Bonding is a technique that is used to increase esthetics of the front teeth. Using white filling material matched to your existing teeth, bonding is applied to close spaces, adjust the size or shape of a tooth or teeth. Different from veneers- bonding typically does not require the removal of much tooth structure. It is often used as short-term measure for esthetic purposes, long term veneers or crown may be recommended. Over time, bonding can become stained much like your natural teeth.
