Compromise to Adjacent Teeth
In the past, the most common method of tooth replacement has been the tooth-supported bridge, but this requires compromising the long-term health of the adjacent teeth. When the teeth on either side of the gap are cut down into pegs for bridges, the tooth structure that has been removed can never be replaced. This undermines the health of the teeth and what ensues is typically structural failure from decay, failed endodontic therapy, or fracture, increasing their risk of loss or the need for additional treatment over time, which can be extensive and costly.
In addition, these teeth now bear the forces that would normally be placed on three teeth, which further weakens the structure of these teeth and it is often necessary to cut down additional teeth to provide the necessary support when the teeth supporting the bridge fail.
