Dental bridges are devices that bridge the gap created by one or more missing teeth. Your face is very important, and also maintaining the structure of your jaw, by keeping all of your teeth, and replacing the ones that are missing. A dental bridge is a prosthesis, and usually created by two crowns- one on teeth that are located on either side of the gap. These two anchoring teeth are called abutment teeth. Dental bridges are supported by natural teeth or implants.
