Crowns are a restorative procedure used to improve your tooth’s shape or to strengthen a tooth. Crowns are most often used for teeth that are broken, worn, or have portions destroyed by tooth decay.
A crown is a “cap” cemented onto an existing tooth that usually covers the portion of your tooth above the gum line. In effect, the crown becomes your tooth’s new outer surface. Crowns can be made of porcelain, metal, or both. Most people prefer porcelain crowns because they mimic the translucency of natural teeth and are very strong.
Crowns or onlays (partial crowns) are needed when there is insufficient tooth strength remaining to hold a filling. Unlike fillings which are composed of restorative material that is placed directly into your mouth, a crown is fabricated away from your mouth. 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.
