In dentistry, a bridge is specifically designed to replace one or more missing teeth by anchoring to adjacent teeth for support. It spans the gap created by the lost teeth and typically consists of one or more artificial teeth (pontics) held in place by dental crowns that are mounted on the abutment teeth. This type of appliance is a durable solution that restores functionality and aesthetics, allowing the patient to chew properly and maintain facial structure.

While other options also address tooth loss, they serve different purposes. A retainer is primarily used to hold teeth in position following orthodontic treatment and is not intended to replace missing teeth. A partial denture is designed to replace missing teeth but is removable, unlike a bridge, which is a fixed solution. A crown is used to cover or protect a damaged tooth but does not replace missing teeth on its own. Therefore, the bridge stands out as the best answer for specifically replacing lost or damaged teeth with a permanent solution.
