A bridge may be used to replace missing teeth, help maintain the shape of your face, and alleviate stress on your bite. A bridge replaces missing teeth with artificial teeth, looks great, and literally bridges the gap where one or more teeth may have been. Your bridge can be made from gold, alloys, porcelain, or a combination of these materials and is bonded onto surrounding teeth for support. There are two basic types of bridges. A fixed bridge which remains in your mouth at all times and is supported by your natural teeth. Removable bridges (partials and full dentures) are removed from the mouth several times a day for cleaning and rest on the gum where the missing teeth are being replaced.
