Dental Crowns

A crown or a cap is a hollow tooth used to cover a badly damaged tooth where filling the tooth may not be enough or to hold a cracked tooth together. It may also be used to hold a bridge together, cover a dental implant or for cosmetic purposes such as tooth discoloration or misshape. A crown is always required after a root canal but not vice-versa.

Before a crown is prepared, the tooth must be filed down to a size where a crown can fit properly. An impression of the remaining tooth is taken to determine its exact mould so that it can be fabricated to the exact standards by qualified laboratory technicians under the supervision of Dr. Peter. A temporary crown, which can be made in office, is placed on the restored tooth while the permanent one is being made at the laboratory.

Crowns can be made of metal such as stainless steel or gold, composite or porcelain. Porcelain crowns are the most natural looking albeit not as strong as metal ones which tend to be used in the back of the mouth due their ability to withstand chewing pressure but lack the attractiveness. In some cases, porcelain can be fused to metal to make the tooth both strong and attractive. “All-zirconia” crowns, the latest in crown technology, are gaining popularity because they are combine the best of metal and porcelain crowns in that they are almost as strong as metal crowns and have the natural tooth color that porcelain offers.
