A dental bridge is a false tooth that is used to fill the gap created by a missing tooth or teeth. A gap between your teeth can be potentially dangerous to your dental health, as it can cause your teeth to shift resulting in a change in your bite that could be painful. Dental bridges help alleviate this problem by using the two surrounding teeth as anchors to hold a false tooth in the place where the gap is. Typically, porcelain crowns are placed over the surrounding teeth, and the false tooth, known as a pontic, is fused between them. There are three types of dental bridges that are commonly used today:
1. Traditional fixed bridge - This is the most common type of dental bridge, in which porcelain crowns are placed over the two surrounding teeth and used as anchors to hold the false tooth in place. The false tooth is usually made of either porcelain fused with metal or ceramics.
2. Cantilever bridge – A cantilever bridge is used when teeth are present on only one side of the gap. These are used typically in areas of your mouth that don’t experience an intense chewing load, such as your front teeth.
3. Resin-bonded bridge - In a resin-bonded bridge, metal bands are bonded to the surrounding teeth with resin and used to hold a plastic false tooth in place. This type of bridge is typically used in areas of the mouth that undergo less stress, such as the front teeth.
