Our choices in materials for crowns are constantly evolving. The history of your choices for crowns used to be either a full metal crown (in areas where as esthetics weren’t a concern), or a tooth colored crown which had a metal base with porcelain baked over top. The disadvantage of the porcelain crowns to a metal crown was that these crowns were more likely to experience chipping where the metal and porcelain were joined together.
Today, all porcelain crowns are an excellent choice when recreating the form and function of a heavily restored or damaged tooth. Because dental porcelain has evolved in strength and esthetics, it can be sculpted with beautiful results to replicate the look of your natural tooth while providing superior strength.
Crowning a tooth requires two visits. During your first visit, your tooth is shaped and an impression is taken so the laboratory can customize your new crown. All porcelain crowns do require some laboratory time to be created, so between visits you’ll wear a temporary or provisional crown. At your second appointment, the temporary crown is removed and the permanent crown is bonded to your tooth with permanent cement.
Maintaining your all porcelain crown is actually quite simple. Just like all of your teeth, they require routine brushing with non-abrasive fluoride toothpaste and regular flossing.
