Bridges use the teeth on either side of your missing tooth to provide support for the artificial tooth (pontic) that fills the space where your natural tooth is missing.
Before implants were developed, bridges were the state-of-the-art way to replace missing teeth. Bridges are constructed of a strong metal frame, usually a gold alloy, either by itself or covered with porcelain to look like a natural tooth. The bridge is cemented or glued to the natural teeth on either side of the space left by the missing tooth. The crowns on the natural teeth serve as abutments or retainers to provide support for the replacement tooth. The goal of the bridge is to restore chewing function, keep the teeth from moving, and restore your appearance.
