The affected tooth is reshaped so that it can be augmented by a natural - looking synthetic material, usually porcelain. This procedure is also beneficial for teeth that show wear and tear or are cooked.
What are Dental Crowns?
Crowns are a type of dental restoration which, when cemented into place, fully cup over the portion of a tooth that lies at and above the gum line. 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 (meaning some sort of dental ceramic), metal (a gold or other metal alloy), or a combination of both. Other terms that are used to refer to dental crowns are "dental caps" and "tooth caps."
Why do teeth need Dental Crowns?
A dentist might recommend placing a dental crown 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
For guarding and protecting a decayed or loose gum tooth from breaking
To bind together fragments of a cracked tooth
For filling the decayed tooth enamel
To hold a dental bridge in place
For covering and restoring a misshaped or severely discolored teeth
To cover a dental implant
Advantages :
Dental crowns offer a big advantage over dental fillings because they are fabricated "away from the mouth". As the dental crown is made in the dental laboratory, the technician can visualize and examine all aspects of bite and jaw movements, from a variety of angles, and sculpt the dental crown for a perfect anatomy. This ensures a great deal of accuracy for comfort and fit.
