A bridge is used to replace one or more missing teeth. They are made of gold, a mix of metals, porcelain, or porcelain fused to metal. A bridge is made up of two crowns linked together by a replacement tooth. The natural teeth on either side of the missing tooth need to be shaped so that the crowns can fit over them. The natural teeth will support the replacement tooth and bare the pressure of chewing. Similar preparation to that of a crown procedure is required to properly fit a bridge. The dentist will fabricate a temporary bridge to prevent any additional movement of the teeth while the laboratory prepares the final bridge.
Dentures (also known as false teeth) are prosthetic devices constructed to replace missing teeth, and which are supported by surrounding soft and hard tissues of the oral cavity. Conventional dentures are removable, however there are many different denture designs, some which rely on bonding or clasping onto teeth or dental implants. There are two main categories of dentures, depending on whether they are used to replace missing teeth on the mandibular arch or the maxillary arch.
