Dental bridges are one of the options available to us when damaged or missing teeth must be replaced. While crowns are the preferred option, sometimes the tooth is too damaged to support one. In these situations, a bridge can be used to hold the remaining teeth in place and prevent them from taking on too much pressure when biting and chewing. There are three types of dental bridges.
Traditional dental bridges need healthy teeth on both sides of the gap; these teeth are used to support the prosthetic tooth. The supporting teeth are shaped and then have a crown placed on them; the middle tooth is removed or mostly removed and a prosthetic is used in its place. We can create porcelain and porcelain/metal crowns for traditional bridges.
The cantilever dental bridge is mostly the same as the traditional bridge except it is used when one side of the missing tooth does not have another tooth for support. Instead, two crowns are used, one covering the missing tooth and one covering the support tooth, and then a pontic is used to provide support where there is no supporting tooth. In some cases, these can be made using just one crown and the pontic.
This type of dental bridge requires support teeth but does not require as much preparation as a traditional bridge. Instead of preparing the teeth to be the supports, metal bands and resin are used to attach the prosthetic tooth. The metal bands are on the backs of the teeth so they are not visible. This is generally uses for highly visible teeth, like the two front teeth.
