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.
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.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 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.
The ADA says that 85% of crowns and bridges are replaced by 10 years.
How long they last depends on
· The shape and quality of the original tooth
· Fluoride exposure
· Brushing and flossing
· Regular cleaning visits
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.
