A dental crown, also commonly referred to as a cap, is a covering that completely encases the entire surface of the tooth. A crown restores the tooth to its original shape and size, and protects and strengthens the tooth structure that cannot be restored with other types of tooth restorations. The most popular type of crown is the porcelain crown, which is tooth colored. Not only does it have the same color, it also matches the shape and size of your teeth to give you a long-lasting and beautiful smile.
Common reasons crowns are used:
Broken or fractured teeth
The procedure for getting a crown usually involves two appointments. In the first appointment, highly accurate impressions (molds) are taken to create your custom crown. A mold for a temporary crown is also taken, and the temporary crown stays on your teeth for about two weeks, when your custom crown is delivered by the dental laboratory. Your tooth is cleared of the decay and shaped to accept the crown properly. Your temporary crown is placed with temporary cement and your dentist will check your bite to make sure you are biting properly.
During your second appointment, the temporary crown is removed, the tooth is cleaned, and your new crown is placed carefully and adjusted so that the spacing and bite are correct.
