Dental bridges are used to replace one or more missing teeth. They are permanently cement on the adjacent teeth. It requires shaving a small portion of the adjacent teeth to the missing teeth in preparation to support a new bridge. Usually, they are 3 teeth long and supported by 2 natural teeth, but sometimes they are longer and need to be supported by more than 2 natural teeth, and that depends on the number of missing teeth we are trying to replace with a dental bridge.
