American Dental Association answeredA fixed bridge (a restoration that replaces or spans the space where one or more teeth have been lost) is commonly cemented or bonded to the natural teeth next to the space left by the missing teeth. An artificial tooth (called a pontic) replaces the lost natural tooth, and restores its function. A pontic is attached to a crown (restoration that covers a tooth). Crowns, which are cemented on adjacent repaired teeth, serve as retainers that support the fixed bridge.Helpful? 1 person found this helpful.
