Derby Dental Crowns

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.

Dental crowns can be used to restore a tooth's shape and strength.

Since a dental crown that has been cemented into place essentially becomes the new outer surface for the tooth, it is easy to imagine how the placement of a crown can restore a tooth to its original shape. It's also easy to see how a dental crown can help to strengthen a tooth by way of being a hard outer shell that encases the tooth structure that lies within it. For both of these reasons, dental crowns are routinely made for teeth that have broken, worn excessively, or else have had large portions destroyed by tooth decay.

It is conceivable that a dental filling, as an alternative, could be used as a means to restore a tooth's shape. Dental crowns however offer your dentist a big advantage over dental fillings by way of the fact that they are fabricated "away from your mouth." By this we simply mean that dental crowns are fabricated in a dental laboratory by a dental technician. Dental fillings, in comparison, are created "in your mouth" by way of your dentist placing the filling material directly upon your tooth.

When a dental crown is made the dental laboratory technician can visualize and examine all aspects of your bite and jaw movements, from a variety of angles, and then sculpt your dental crown so it has the perfect anatomy.
