A bridge is an appliance permanently fixed in the mouth to replace missing teeth. It uses remaining teeth to support the new artificial tooth or teeth.

A conventional fixed bridge consists of crowns that are fixed to the teeth on either side of the missing tooth. False teeth are rigidly attached to these crowns. An enamel-bonded bridge uses a metal or porcelain framework to which the artificial teeth are attached. Resin is then used to bond with supporting teeth.
