What Types of Teeth Can Porcelain Veneers Be Placed on?

As long as there is adequate enamel and tooth structure as well as proper occlusion a veneer should be able to placed on the teeth.  Canine, bicuspids and molars can accept veneers. 

As long as the bite is not changing, a veneer can be placed on any tooth, including molars and premolars.  If the bite is changing (opening up; distancing the nose from the chin) then a full crown or onlay would be needed on molars and premolars.

When doing smile makeovers, most cases are veneering from premolar to premolar, sometimes including the molars.

As long as the tooth has adequate enamel and structure, a porcelain veneer can be placed on it. Even more important, however, is the occlusion, or the way the upper and lower teeth meet eachother. That really has to be taken into account. That being sais, Porcelain Veneers CAN be placed on canines, bicuspids and molars, as well as on anterior incisors.
