After you lose a tooth, your dentist may suggest that you get a bridge. A bridge can keep your other teeth from moving out of place. Once a bridge is placed, it works just like your natural teeth. Bridges can be made from gold, alloys, porcelain or a combination of these materials. Unlike a removable bridge, which you can take out and clean, a fixed bridge can only be removed by a dentist.
