Historically, a bridge was used to replace a single missing tooth. Bridges are constructed of metal sub-frames with tooth-colored porcelain applied to approximate the natural color of your existing teeth.
Bridges use the teeth on either side of your missing tooth to provide support for the artificial tooth that fills in the space where your natural tooth is missing.
The goal of the bridge is to restore chewing function and achieve an acceptable esthetic outcome.
Unfortunately, bone under the replacement tooth is no longer stimulated by chewing and is often resorbed into the body, creating a slowly growing gap between the replacement tooth and the gums.
