A crown is a restoration that covers or "caps" a tooth to restore it to its normal shape and size, strengthening and improving the appearance of a tooth. Crowns are necessary when a tooth is generally broken down and fillings won't solve the problem. Often a porcelain crown is a better choice for cosmetic improvement because they mimic the translucency of natural teeth and have superior strength.
Crowns are cemented onto an existing tooth which fully cover the portion of your tooth above the gum line. In effect, the crown becomes your tooth's new outer surface. If a tooth is cracked, a crown holds the tooth together to seal the cracks so the damage doesn't get worse. Crowns are also used as an improvement over a large filling when there isn't enough of the tooth remaining to help attach a bridge, protect weak teeth from fracturing, restore fractured teeth or cover badly shaped or discolored teeth.
Unlike fillings which are applied 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.
Crowns should last approximately 10 to 15 years. However, with good oral hygiene and supervision most porcelain crowns will last much longer. Some damaging habits like grinding your teeth, chewing ice or fingernail biting may cause this period of time to decrease significantly.
