A crown (or cap) is a covering that encases the entire tooth, restoring it to its original shape and size. Crowns are a good treatment option when the integrity of a given tooth has been damaged to the point where fillings or other types of restorations can not properly repair it. While several types of crowns are available, porcelain crowns are popular because they can mimic the natural color of teeth.
Fortunately, crowns function almost exactly like normal teeth, so you will only rarely notice that it is even present. The dentist will give you care instructions and the continued practice of brushing, flossing, and visiting the dentist regularly will help ensure the proper functioning of your new crown. The high durability of porcelain crowns helps them to last many years, but they may eventually need to be replaced.
