Dental veneers are most often used to alter the appearance of the most visible teeth in the smile. Dental veneers are frequently used on the upper and lower front teeth as well as the premolars which are the teeth in between the canine (eye tooth) and the molars. The anterior teeth, which are the teeth located at the front of the smile, are good candidates for veneers in most cases. The posterior teeth, the back ones that we do most of our chewing with, are not good candidates for veneers due to the bite forces they are subjected to during chewing and clenching.
