A bridge, also called a fixed bridge or a fixed dental prosthesis, is a dental restoration that replaces one or more missing teeth. It extends across an area that has no teeth and is typically made up of an artificial tooth fused between 2 crowns. (A crown is a hollow, artificial tooth that fits over a natural tooth or a dental implant). The bridge is held firmly in place by your own teeth on each side of the missing one(s) or by dental implants. A bridge is cemented and not removable by the patient. With proper home care, a bridge can last 10-15 years, in some cases, much longer.
