Veneers are recommended for teeth with stains that cannot be whitened away, or for teeth that are misshapen or unattractive.  Some teeth require no preparation at all.  For others, a thin layer of enamel is removed from the front of your tooth.  An impression is taken of your teeth and sent to a dental lab where a dental artist creates the shape and color that are perfect for your smile.  The final veneers are thin porcelain and are cemented to the front of your teeth.
