A bridge is a dental restoration used to replace missing teeth. It permanently attaches artificial teeth to natural teeth. A bridge consists of pontics and abutments that are connected. When teeth are missing, unusual stresses are placed on the gums and other oral tissues, causing a number of potential harmful disorders. A bridge helps support your lips and cheeks. The loss of a back tooth may cause your mouth to sink and your face to look older. Oral functionality and appearance are important reasons for doing a bridge.
