Bridges are crowns that are attached together, suspending the crown portion of a false tooth in or over the space left by the missing tooth. A bridge can be used to replace one or several teeth. Sometimes a bridge is used to splint loose teeth together in order to make the teeth more stable. Bridges are usually made of metal covered with either porcelain or resin. Some of the new bridges are made of all resin, or all ceramic materials. They are cemented or bonded onto the existing prepared teeth and are not easily removed once placed. The bridge teeth can be brushed the same as natural teeth, but since they are attached together, they must be flossed differently by using a floss thread or other device.

The teeth are generally the same shape as natural teeth. However, if the existing teeth (abutments) that are used to anchor the bridge have moved from their original position because a tooth or teeth have been missing for years, the added tooth (pontic) may be longer or shorter than the tooth that it is replacing. With a bridge, the false tooth will most often butt up against the soft tissue ridge where the removed tooth was.

The shape of the tongue side of the false tooth varies. It is usually smaller on the tongue side and completely fills the space. Food will have more of a tendency to collect in this area, so you must be prepared to clean it. If the missing tooth has been gone a long time, the ridge may have shrunk considerably, and the pontic tooth will be longer than the teeth on either side. If this is the case, there are several periodontal procedures that can be done prior to the construction of the bridge. These procedures will build up the tissue to its former height. The more your mouth has changed from its normal state, the harder it is to make new teeth look and feel natural.
