A bridge is a fixed dental restoration used to replace a missing tooth by joining an artificial tooth permanently to adjacent teeth

Types of bridges vary, depending upon how they are fabricated and the way they anchor to the adjacent teeth. Conventionally, bridges are made in the laboratory using a variety of materials. A bridge is fabricated by reducing the teeth on either side of the missing tooth or teeth by a preparation pattern determined by the location of the teeth and by the material from which the bridge is fabricated.

The materials used for the bridges include gold, porcelain bonded to metal or in metal free materials. The amount and type of reduction done to the adjacent teeth varies slightly with the different materials used.
