There are several types of fixed dental bridges (cannot be removed), including conventional fixed bridges, cantilever bridges and resin-bonded bridges. Some bridges are removable and can be cleaned by the wearer; others need to be removed by a dentist.
Porcelain, gold alloys or combinations of materials are usually used to make bridge appliances.
Appliances called implant bridges are attached to an area below the gum tissue, or the bone.
