A crown is made of porcelain or metal and is placed on a tooth in order to restore it or to strengthen it. A bridge, otherwise known as a fixed partial prosthetic, is used to replace missing teeth and cannot be removed by the patient.
An advantages of an inlay is to preserve the dental structure. It is possible to replace defective composites or amalgams. Gold is an outstanding material; it is durable, biocompatible and will not cause wear on opposing teeth. If you prefer a natural, white color, porcelain is also available for inlays.
