If you have missing teeth , your dentist can close — or bridge — the gaps in your smile with dental bridges. A dental bridge is a false tooth (called a pontic) that is held in place by the abutment teeth on either side of the gap. Although pontics can be made from a variety of materials such as gold, typically they’re made from porcelain to aesthetically blend in with your natural teeth.
Dental bridge types
There are four main types of dental bridges:
Traditional dental bridge
A traditional dental bridge consists of a false tooth or teeth being held in place by dental crowns that have been cemented onto each of the abutment teeth. A traditional bridge is the most popular type of dental bridge and can be used when you have natural teeth on both sides of the gap created by your missing tooth.
Cantilever dental bridge
Although similar to a traditional bridge, the pontic in a cantilever dental bridge is held in place by a dental crown that is cemented to only one abutment tooth. For a cantilever bridge, you only need one natural tooth next to the missing tooth gap.
Maryland dental bridge
Similar to a traditional bridge, Maryland dental bridges employ two natural abutment teeth, one on each side of the gap. However, while a traditional bridge uses dental crowns on the abutment teeth, a Maryland bridge uses a framework of either metal or porcelain that is bonded onto the backs of the abutment teeth.
Like a traditional bridge, a Maryland bridge can only be used when you have a natural tooth on each side of the gap caused by the missing tooth or teeth.
Implant-supported dental bridge
As the name implies, implant-supported bridges use dental implants as opposed to crowns or frameworks. Typically, one implant is surgically placed for every missing tooth, and these implants hold the bridge in position. If one implant for each missing tooth isn’t possible, the bridge may have a pontic suspended between two implant-supported crowns.
Considered the strongest and most stable system, an implant-supported bridge commonly requires two phases:
one to embed the implants in the jawbone
a second surgery to place the bridge
It can take a number of months for the procedure to be completely finished.
Dental bridge vs. dental implant
Implant supported prosthesis is a stand-alone product while a tooth supported bridge requires reduction of sometimes good teeth. A dental bridge may need to be replaced every 10 to 20 years, depending on proper care, while implants are considered a permanent solution. There are factors that can reduce the life of all types of bridges, including implants, such as dental hygiene.
Why do I need a dental bridge?
When you have a missing tooth or missing teeth, it can affect you in a number of ways. A dental bridge can address those changes, including:
restoring your smile
restoring the ability to properly chew
restoring your speech and pronunciation
maintaining the shape of your face
re-adjusting your bite to properly distribute the force when you chew
preventing your remaining teeth from moving out of the correct position
If you’re missing a tooth or a number of teeth, you have different replacement options to discuss with your dentist. There are many benefits to using dental bridges, and there are many factors — including costs — that you should consider before making a decision.
