Crowns
Crowns are synthetic caps that are made of porcelain and placed on the top of a tooth. They are used to restore a tooth's function and appearance following a restorative procedure such as a root canal.
Crowns are also used to attach bridges, cover implants, prevent a cracked tooth from becoming worse or an existing filling that is in jeopardy of becoming loose or dislocated. Crowns may also be used aesthetically, and are applied when a discolored or stained tooth needs to be restored to its natural appearance.
Procedures
Usually, teeth will need to be reduced in size to accommodate a crown. Then, a cast is made of the existing tooth to make an impression. The impression is sent to a lab that manufactures a custom-designed crown. Sometimes, a temporary crown is applied until the permanent crown is ready. Permanent crowns are cemented in place.
Caring For Your Crowns
With proper care, a crown can last up to eight years. It is important to floss in the area of the crown to avoid excess plaque or collection of debris around the restoration.
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. Some bridges are removable and can be cleaned by the wearer; others need to be removed by a dentist.
