A dental bridge is a false tooth that is used to fill the gap created by 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
Compared to fillings which just cover a small portion of a tooth, a crown (or cap) encases the entire visible portion of a tooth. In effect, the crown acts as the tooth's new outer surface. A dental crown is used when a tooth is broken or decayed to such an extent that fillings aren't able to repair the problem. The crown is able to provide a protective shell around the damaged or decayed tooth to strengthen it, as well as to improve the appearance of the tooth. They can also help restore a tooth to its original shape, are used commonly for teeth that have been broken. While crowns come in different materials, the most common crowns typically have some mixture of porcelain in them to give them a look and feel similar to a natural tooth.
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. Multiple visits may be necessary to check and adjust the fit.
