What are Crowns?

Crowns are a dental restoration used to restore a tooth’s original shape, to strengthen a tooth or to improve the cosmetic appearance of a tooth. Crowns are “caps” cemented onto an existing tooth which fully cover the portion of your tooth above the gum line. Crowns can be made of porcelain, metal, or both. Porcelain crowns are most often preferred because they mimic the translucency of natural teeth and are very strong.

When do I need a crown?

Crowns are most often used for teeth that are broken, worn, or have portions destroyed by tooth decay. Crowns are also necessary to protect the tooth from breaking when the tooth has received a root canal. They are often preferable to large silver amalgam fillings.

What is the procedure?

The procedure normally involves two appointments. One appointment is for the dentist to prepare the tooth and have a mold
(or impression) taken of the prepared tooth. At the end of this appointment you receive a temporary crown. From there, your crown is created in a lab from your unique tooth impression which allows a dental laboratory technician to examine all aspects of your bite and jaw movements. Your crown is then sculpted just for you so that your bite and jaw movements function normally once the crown is placed. The second appointment is to cement the crown into place using permanent cement.
