Crowns and Bridges
Crowns are a type of dental restoration which, when cemented into place, fully cup over the tooth.
In comparison, fillings are dental restorations that fill in or cover over just a portion of a tooth. Since dental crowns encase the entire visible aspect of a tooth, a dental crown in effect becomes the tooth's new outer surface.
Crowns can be made out of porcelain, metal (a gold or other metal), or a combination of both.
Dental crowns are recommended for a variety of reasons but, in general, most of these reasons will usually fall within one of the following basic categories:
- To restore a tooth to its original shape.
- To strengthen a tooth.
- To improve the cosmetic appearance of a tooth
