Bridge is a term used when one or more false teeth are permanently attached to the adjacent natural teeth. This is most commonly done using crowns on the teeth supporting the bridge. The false tooth is made of the same material as the adjacent crowns and the bridge is fabricated as a single unit but shaped to give the illusion of individual teeth. The false tooth can also be shaped and positioned to give the illusion of a tooth with a root imbedded in the gums and jawbone, just like a natural tooth. Dentists use the term fixed to describe something that is permanently attached. A fixed bridge therefore is not removable for cleaning and must be brushed and flossed in your mouth, just like your teeth. A bridge is one of the ways your dentist can use to replace that missing tooth.
