Crowns & Bridges in Sudbury, MA
Bridges
Bridges are natural-looking dental appliances that can replace a section of missing teeth. Because they are custom-made, bridges are barely noticeable and can restore the natural contour of teeth as well as the proper bite relationship between upper and lower teeth.
Bridges are sometimes referred to as fixed partial dentures because they are semi-permanent and are bonded to existing teeth or implants. There are several types of fixed dental bridges (cannot be removed), including conventional fixed bridges, cantilever bridges, and resin-bonded bridges. Unlike a removable bridge, which you can take out and clean, your dentist can only remove a fixed bridge.
Porcelain, gold alloys, or combinations of materials are usually used to make bridge appliances. Appliances called implant bridges are attached to an area below the gum tissue or the bone.
Creating a Bridge
The number of abutment teeth necessary to replace missing teeth is influenced by the number of missing teeth, the size, and length of the abutment tooth roots, the amount of bone support each abutment tooth has, as well as where in the mouth the missing tooth is located. For example, if you have three missing teeth, four abutment teeth may be necessary, thereby creating a seven-tooth bridge. Engineering and designing of the bridge require an understanding of how to replace teeth, as well as the biology of the supporting gum and bone tissue.
Crowns
Crowns are synthetic caps, usually made of a material like porcelain, placed on the top of a tooth.
Crowns are also used to attach bridges, cover implants, prevent a cracked tooth from becoming worse, or an existing filling is in jeopardy of becoming loose or dislocated. Crowns also serve an aesthetic use and are applied when a discolored or stained tooth needs to be restored to its natural appearance.
Procedures
A tooth must usually be reduced in size to accommodate a crown. An impression is then made from the existing tooth to create a custom-designed crown. The impression is sent to a special lab, which manufactures a custom-designed crown. In some cases, a temporary crown is applied until the permanent crown is ready. Permanent crowns are cemented in place.
Crowns are sometimes confused with veneers, but they are quite different. Veneers are typically applied only to relatively small areas.
Caring For Your Crowns
With proper care, a good quality crown could last up to eight years or longer. It is very important to floss in the area of the crown to avoid excess plaque or collection of debris around the restoration.
Certain behaviors such as jaw clenching or bruxism (teeth grinding) significantly shorten the life of a crown. Moreover, eating brittle foods, ice or hard candy can compromise the adhesion of the crown, or even damage the crown.
