A bridge is a fixed dental restoration used to replace one or more missing teeth by joining an artificial tooth definitively to adjacent teeth. Bridges are usually made of a precious metal. If the bridge will show, porcelain is then bonded to the base. Sometimes, there are other non-precious metals used in the base for strength. Although a bridge may seem costly they can be a wise investment that will give many years of good service. It will also improve your appearance and bite. A bridge uses the considerable skill of the dentist and technician. You need to clean your bridge every day, to prevent problems such as bad breath and gum disease. You also have to clean under the false tooth every day. Your dentist or hygienist will show you how to use special floss, as a normal toothbrush cannot reach.
