While a dental implant might be the most ideal way to replace a missing tooth, a dental bridge can also be used to accomplish the same goal. Bridges are made by crowning the teeth on both sides of the missing tooth. A single prosthetic, resembling three healthy teeth, is cemented to the newly crowned teeth. Although rarely recommended first, a dental bridge can accomplish replacing a missing tooth and restoring a broken down adjacent tooth. Most bridges are made out of cast gold or zirconia, although some are made from porcelain fused to metal. Typically, bridges are also a more cost-effective way to replace a missing tooth than an implant.
