Tooth bonding can be used for cosmetic purposes. A veneering of dental bonding can enhance the appearance of a tooth that is partly stained or discolored. Bonding can also used to close teeth gaps and to reshape and re-align teeth that have little imperfection such as chipping and misalignment.

Another use of tooth bonding is for creating composite fillings. The restorative used in tooth bonding, or the dental composite, is also the material used for making natural tooth-colored fillings. This is a good alternative to silver fillings because the former is less noticeable.
