Bridges can be used to replace one or more missing teeth. Dental bridges are considered cosmetic (a visual improvement), but also have a good effect on the prevention of future dental problems. People with missing teeth have a higher risk of developing tooth decay, periodontal disease, and a temporomandibular joint disorder (TMJD). Also, in addition to assisting with prevention on medical problems, bridges can help a person speak more clearly and smile more attractively.
