A bridge is an excellent way to replace a missing tooth and keep a beautiful smile. A bridge replaces one or more missing teeth by attaching to the teeth on either side of the empty space. Why replace a missing tooth? Teeth need each other for support. When teeth are lost, the biting force changes on the teeth next to the space and the teeth begin to shift. When the opposing tooth no longer has anything to bite against it will also begin to shift. The whole side of the mouth can be compromised by a single missing tooth.
