Dental bridges are used to fill the gap caused by the missing teeth. They are usually crowns for the teeth (abutment teeth) on either side of the gap. False tooth are placed between the abutment teeth.
A bridge is made up of two or more crowns for the teeth on either side of the gap -- these two or more anchoring teeth are called abutment teeth -- and a false tooth/teeth in between. These false teeth are called pontics and can be made from gold, alloys, porcelain, or a combination of these materials. Dental bridges are supported by natural teeth or implants.
