A dental crown, also sometimes called a cap, is a perfectly fitted restoration that repairs and strengthens a tooth that has fractured, has a large cavity, an old filling that has failed or has had root canal therapy. Unlike an inlay or onlay, a crown completely covers the tooth. Crowns can also be used for cosmetic purposes, enhancing the appearance of a tooth that is discolored or misshapen.
There are many different types of crowns including porcelain crowns, porcelain fused to metal crowns and full metal crowns. Your dentist will determine which type is best suited for your particular need. This matter will be discussed with you before the procedure.
While the tooth is numb, the dentist will prepare the tooth by removing any decay and shaping the surfaces of the tooth to properly fit the crown. Once these details are accomplished, your temporary crown will be placed with temporary cement and your bite will be checked to ensure you are biting properly.
At your second appointment your temporary crown will be removed, the tooth will be cleaned, and your new crown will be carefully placed. A few adjustments may be necessary to ensure a proper fit and that your bite is comfortable. You will be given care instructions and encouraged to have regular dental visits to check your new crown.
