Dental Bridges (Video Available)
A dental bridge is a false tooth that is used to fill the space created by missing tooth or teeth. A space 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 missing tooth is. Typically, porcelain crowns are placed over the surrounding teeth, and the false tooth, known as a pontic, is fused between them.
Types of dental bridges
There are two types of bridges that are commonly used today.
1. Traditional fixed bridge - This is the most common type of 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 to metal or ceramics.
2. Cantilever bridge – A cantilever bridge is used when teeth are present on only one side of the missing tooth. These are used typically in areas of your mouth that doesn’t experience an intense chewing load, such as your front teeth.
How it's done
A minimum of two visits are required for placing a dental bridge. At the first visit, three important steps are completed.
Firstly, the surrounding teeth are prepared to be fitted with a crown. This may including filing down the tooth so that the crown can fit over it.
Secondly, an impression is taken of your teeth which will be sent to a laboratory to prepare the bridge and crown.
Finally, the dentist fits your teeth with a temporary bridge to protect them while the bridge is prepared at the laboratory.
At the second visit, the temporary bridge is removed and the new bridge received from the laboratory is fitted and adjusted.
