Bridges
Bridges are used when 1 or a few teeth are missing. They replace the missing tooth or teeth with false ones. A permanent or fixed bridge is cemented onto specially prepared teeth on either side of the space. Sometimes, though, a removable bridge can be used. A removable bridge clips to the teeth on both sides of the space. You can put a removable bridge in and take it out yourself.
Most of the time, a removable bridge has an acrylic base with metal clasps or a frame that is made of cast metal. Permanent or fixed bridges can be made from metal, ceramics, or a combination of the two. False teeth are mounted onto the base of a bridge to fill the space where the teeth are missing.
