A bridge is a dental restoration that fills the space where one or more teeth are missing. The bridge restores your bite and helps keep the natural shape of your face. Before you get a bridge, your dentist wants you to know more about the steps involved. He or she can advise which type of bridge is best for you.
A bridge is made up of two or more crowns for the teeth on either side of the gap — these two or more anchoring teeth are called abutment teeth — and a false tooth/teeth in between. These false teeth are called pontics and can be made from gold, alloys, porcelain, or a combination of these materials. Dental bridges are supported by natural teeth or implants.
There are three main types of dental bridges:
- Traditional bridges involve creating a crown for the tooth or implant on either side of the missing tooth, with a pontic in between. Traditional bridges are the most common type of bridge and are made of porcelain fused to either metal or ceramics.
- Cantilever bridges are used when there are adjacent teeth on only one side of the missing tooth or teeth. This is not very common anymore and is not recommended in the back of the mouth where it can put too much force on other teeth and damage them.
- Maryland bonded bridges (also called a resin-bonded bridge or a Maryland bridge) are made of porcelain, porcelain fused to metal, or plastic teeth and gums supported by a metal or porcelain framework. Metal or porcelain wings often on just one side of the bridge are bonded to your existing teeth.
