A bridge is an appliance permanently fixed in the mouth to replace missing teeth. It uses remaining teeth to support the new artificial tooth or teeth. A bridge is made up of two crowns for the teeth on either side of the gap – these two anchoring teeth are called abutment teeth, and false tooth/teeth rigidly attached in between. The false teeth are called pontics. The bridge can be made from gold, alloys, porcelain or a combination of these materials.
