The purpose of a porcelain crown is to wrap around the tooth and replace damaged or missing tooth enamel. We have many types of porcelain crowns available, and we use them depending on several factors including the strength or appearance of the material. On back teeth, we often use Zirconia crowns that are extremely hard, and are able to hold up to the strong forces that are present in your back teeth. Lithium Disilicate or Feldspathic Porcelain are often used on front teeth where the forces are not as strong, but where we want beautiful teeth. The advantage of porcelain crowns is that they look very natural and can be used to create a beautiful smile. When a tooth is cracked, broken, decayed, or damaged, a porcelain crown can wrap around the outer layer of the tooth and replace the enamel.
