A veneer is a thin shell made from a composite or ceramic material that covers the front of the teeth. It is a cosmetic treatment, which improves the appearance of your smile. A crown is used to restore the shape, appearance and the function of a damaged or decayed tooth. The crown is made of ceramic as this material most resembles a natural tooth. CEREC technology is used to make the crown and can be done either in-office or in the laboratory. The bridge replaces one or more missing teeth. When a tooth is lost, it must be replaced as soon as possible to prevent the surrounding teeth from moving. A bridge is made of crowns that have been soldered together and then attached to the adjacent teeth.
