There are three main varieties of dental bridges, and the type your dentist recommends will vary depending on where in your mouth the missing teeth are located.
A traditional bridge is the most commonly recommended treatment for missing teeth. It involves creating crowns to go on the teeth on either side of the gap which acts as anchors for the pontic that will sit in-between them. Traditional bridges are usually made from porcelain that has been fused to ceramic or metal.
Also sometimes referred to as a Maryland bonded bridge, this type of bridge can be created from a variety of materials including porcelain fused to metal, complete porcelain or sometimes plastic teeth and gums that are supported by a porcelain or metal framework. The wings found on each side of the bridge, usually made from metal or porcelain, are securely bonded to your natural teeth.
Cantilever bridges are used when there are only existing teeth that can be used as anchors on one side of the gap. In the past there have been problems with cantilever bridges being used in the back of the mouth as they were found to exert too much pressure on the anchor tooth, causing damage and even breakages.
