Bridges are commonly used to replace a missing tooth or teeth. These restorations are made up of three or four crowns fused together to fill the space left by a missing tooth. The natural teeth on either side of the space are used as retainers to hold the false crowns in place. The procedure is the same as for a traditional crown, with multiple teeth being prepared instead of one. Bridges are a great option to fill a space or replace a failing tooth when the teeth on either side of the space could benefit from strengthening or cosmetic changes as well.
