A bridge is one or more artificial teeth that are cemented into place using the real teeth on either side for support--hence the name. Bridges are a perfect option for filling the space created by a missing tooth. A bridge replaces the missing tooth both functionally and cosmetically. Bridge work is as much an art as it is an exact science. Bridge materials include gold alloys, porcelain bonded to metal alloy, or all-ceramic material made to match your natural tooth color. The choice of material depends on requirements for strength, wear, and/or esthetics.
