A crown is a restoration that covers a tooth in order to restore it to its normal shape and size.
The purpose of the crown is to strengthen the tooth and improve its functionality and appearance. A crown is placed for a number of reasons: To support a large filling when there isn’t enough tooth remaining to attach a bridge to, to protect week teeth from fracturing, (or restore fractured teeth) or to restore a decayed tooth or a tooth treated with root canal therapy.
Crowns are made of various materials. To determine which crown materials are suitable for an individual, the following factors are considered: Tooth location, the position of the gum tissue, the function of the tooth, the amount the tooth that shows with your smile, and the color and shade of the tooth. Crowns are prepared and placed in the following fashion: First, the tooth is prepared by removing its outer portion to accommodate the thickness of the crown. Then, an impression is made to provide an exact model of the tooth. The crown is made from this model. It is then put in place and any necessary adjustments are made. When its position, appearance, feel, etc. are satisfactory, the crown is then cemented into place. Once the procedure is complete, the tooth will not only be stronger, it will feel better and look great.
