A dental bridge is a permanent replacement when missing one or more teeth. Gaps left by missing teeth eventually cause the remaining teeth to rotate or shift into the empty spaces, resulting in a bad bite. The imbalance caused by missing teeth can also lead to gum disease and temporomandibular joint (TMJ) disorders. Bridges span the space where the teeth are missing and are cemented to the natural teeth or implants surrounding the empty space. These teeth, called abutments, serve as anchors for the bridge and require preparation or tooth shaping prior to cementing the bridge. A replacement tooth, called a pontic, is attached to the crowns that cover the abutments. Porcelain or ceramic bridges can be matched to the color of your natural teeth.
