Veneers can be made of composite or ceramic. The composite veneers are cheaper; whereas the ceramic veneers are stronger, less susceptible to staining, and easier keep clean. Veneers that are used as part of a smile design will produce beautiful results.
Composite veneers require one long appointment to complete. The entire veneer is constructed in the dental chair, and polished and shaped on the same day.
Ceramic veneers require two short visits to complete. The first visit involves shaping and then using a special digital camera to scan a mould of the tooth into the computer. The digital mould is e-mailed to a dental laboratory where the onlay is constructed. At a second visit, the constructed onlay is then cemented onto the tooth.
