For cosmetic dentistry to be successful a number of things must be taken into account. These include: 1) An understanding of where we want the tooth position, size, and shape to be before the case even begins. 2) Restorations placed in harmony with the muscles of the face, other teeth, lips, and joints. 3) An understanding of the benefits and limits of the materials used. The definition of the word "veneer" has now blurred as we place "3/4 veneers", 3/4 crowns, and "no-prep veneers". A knowlegable dentist knows the circumstances when each of these options are most appropriate. There is no need for a blanket decision to only do veneers once or twice or three times on a tooth. If done correctly, hopefully once or twice in a lifetime will be fine. If not, a transition to a crown or "3/4 veneer" is not a huge one and will not feel or look any different. Whichever choice is made, they should not "keep popping off!"
