A crown or cap is a dental restoration that covers the exposed surface of a tooth to strengthen it or improve its appearance. A bridge is a dental restoration to replace one or more missing teeth. It includes an artificial tooth or teeth which are fused to crowns on either side to provide support.
What is the difference between a dental crown and a dental bridge?
While a crown is used to cover an existing tooth, a dental bridge is used to fill in the missing space caused by one or more lost teeth. A bridge is made up of one or more false teeth with one crown on either end of the bridge.
What is a dental bridge?
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
- cantilever
- Maryland
- implant-supported
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
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 surgeries:
- 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.
