There are several materials used to make dental crowns, like metal crowns, but we believe in offering our patients the best service, and we believe that porcelain crowns are better for the good being of our patients. Porcelain crowns are placed on top of the damaged tooth and act as a cap that will fix and reshape the size and appearance of your tooth. Here at Potomac Crown Dentist 20878, we only use porcelain to make dental crowns.
