When a single tooth is missing, the two most common treatment options are the traditional tooth supported dental bridge or an implant supported crown. When a traditional bridge is used to replace a missing tooth, the adjacent teeth are drilled down in order to fit the cemented bridge in place. This method of tooth replacement can be very esthetic and functional for a period of time. However, adjacent teeth are forever compromised, and a tooth supported bridge does not replace the bone that previously surrounded the root. Since there is no longer a root to hold the bone in place, the bone deteriorates, or melts away.
