A dental bridge is used to fill a gap left by extracted teeth. A bridge is made up of two or more crowns. The bridge is placed on top of the two teeth which are immediately before and after the missing teeth. The two teeth hold the bridge while the false teeth fill the gap.
A dental bridge fill the gap left by missing teeth, however, it is advised to get an implant done instead of a bridge to fill the gap. The two teeth that hold the bridge are drilled so that they can hold the bridge. The drilling causes the teeth to lose natural strength and may become sensitive. In case of dental implant, the adjacent teeth are not touched by the procedure, so there is no drilling of any teeth. Also, the implant is placed inside the bone, so it gives better strength than a false teeth on the bridge to fill the gap.
