How A Dentist Will Reduce The Pressure Concerns Of A Cantilever Bridge

If you want to have a single tooth physically replaced in a permanent manner without having to go through surgery, then a bridge may be a good option over a dental implant. Bridges are typically three part devices that are bonded together. A full tooth, or pontic, sits in between two crowns. However, there are some cases where a solid a tooth is not present on either side of the missing tooth. When this happens, something called a cantilever bridge can be constructed. While a cantilever bridge is an ideal choice in some cases, there may be some concern about too much pressure being placed on the abutment or crown part of the device. Keep reading to learn how your dentist may try to reduce these sorts of concerns.

A Two Crown Device May Be Created

While some cantilever bridges are created to replace a missing molar, others may be formed to repair an incisor or another one of the front teeth. When this is the case, there are several circumstances that may make it difficult to place a traditional bridge. For example, if the tooth to the right or the left have already been fitted with a crown, then it is not a good idea to remove it. This can cause the tooth to crack, especially if the crown was placed due to a substantial weakness or damage concern. 

In the type of situation, and in others, your dentist can still create a bridge with two solid abutments and one pontic. However, the two attachment teeth will be the two available and healthy teeth on the right or left of the missing tooth. For example, if your canine is missing, then both the first and second premolars can be used to attach the bridge. In this way, the pontic will still sit on the end of the bridge, like if a traditional cantilever bridge is constructed. However, the dental appliance will have twice the support and pressure will be less of an issue.

A Porcelain And Metal Device May Be Used

Just like traditional crowns, your dentist will have a wide variety of material options when it comes to the construction of your bridge. This may mean that the device is not constructed out of porcelain alone. Porcelain is typically used when bridges are formed to help retain and enhance the aesthetic appeal of the mouth. However, porcelain does not have the same strength as steel. To add strength to the single porcelain crown or abutment, a layer of stainless steel is added to the crown underneath it. 

The steel of the crown sits against the biting edge of the abutment tooth. This gives the tooth strength where it needs it most, while the porcelain on top make the tooth look natural.
