Dental bridges are custom oral appliances created by your dentist to replace missing teeth & restore your smile. Bridges are usually made to resemble your natural teeth, but can be made from a variety of materials, including porcelain, alloys or gold. There are several types of bridges that vary in stability, application & cost. Fixed bridges are cemented to the natural teeth on either side of the missing tooth gap, & implant-supported bridges use an artificial metal tooth root to attach the bridge to the bone of your jaw. Your dentist can recommend which type of bridge is best for you.
