Lumineers or no prep veneers can be done in some cases successfully without shaving down your teeth. Because there is no preparation involved, you can see how they would look before actually having them fabricated. Your dentist would have to take impressions of your teeth and have a waxup created showing how the veneers would look. An impression is taken of the waxup creating a matrix. By placing self curing temporary material in the matrix in the areas of the teeth to be veneered, and then placing the matrix in your mouth over your teeth, upon removal of the matrix in two minutes, the temporary material will remain on your teeth and give you a preview of how your teeth will look with the no prep veneers. Since they are adding to the dimension of your teeth, they should provide a widened smile for you. Your dentist will charge you a fee for this service, but it is well worth it to make sure you will be satisfied with your final veneers and not get an unpleasant surprise. The fees for no prep veneers are very comparable to prepped veneers where teeth are shaved down because the same laboratory fees will be incurred by your dentist. You should expect between $1000 and $2000 per tooth depending on the experience, skills, and expertise of the dentist and laboratory technician.
