Bridges are used if more than one tooth is missing. If missing teeth are not filled immediately, then the void space in the teeth can interfere with masticatory function. So dentures like Bridges are needed.
This dental bridge will usually cover the empty space due to missing teeth. Usually the bridge of the tooth is in the middle of the crown. While the crown is at both ends of the Bridges. In other words, Bridges are dentures that bridge two crowns—which cover dental implants.
