Bridges
A bridge, also called a “fixed bridge” or a “fixed dental prosthesis,” is a dental restoration that replaces one or more missing teeth. It extends across an area that has no teeth and is typically made up of an artificial tooth fused between 2 crowns. (A crown is a hollow, artificial tooth that fits over a natural tooth or a dental implant.) The bridge is held firmly in place by your own teeth on each side of the missing one(s) or by dental implants. A bridge is permanent and cannot be removed.

Types of bridges
There are different types of dental bridges. Your dentist or prosthodontist will recommend the most appropriate one depending on the location of the missing tooth (or teeth) and the condition of your teeth, mouth and gums.
Traditional bridges are used if there are natural teeth on each side of the gap where the tooth is missing. (As an alternative to a bridge, your dentist may suggest a single implant to replace a missing tooth between 2 healthy teeth. An implant will prevent you from having to get your healthy teeth filed down in preparation for the crowns.)
Implant bridges are used if you don’t have healthy teeth or enough teeth to support a bridge, or when several or all teeth are missing. A custom-made bridge is anchored to the dental implants. Your dentist will first determine if dental implants are right for you.
Resin-bonded bridges, also known as "Maryland" bridges, are used when the missing teeth are in the front of the mouth. This type of bridge involves the artificial teeth being fused together to metal bands and cemented to the back of your natural teeth.
Cantilever bridges are used when there are healthy teeth on only one side of the missing tooth or teeth. This procedure involves anchoring the artificial tooth over one or more of your natural adjacent teeth.
Caring for your bridge
If you take good care of your bridge, it should generally last for about 10 years, or perhaps longer. Like natural teeth, bridges need to be brushed and flossed every day. Your dentist will show you how to use a floss threader to floss under and around the artificial tooth (or teeth) in the middle of the bridge. Regular dental visits and professional cleaning are also important. If you have an implant bridge, your dentist will show you how to properly care for them.
