What is the difference between non-prep veneers and conventional veneers?
Non-prep veneers are applied to uncut teeth. They are 0.1 to 0.3 mm thick. Normal veneers are 0.8 to 1 mm thick. The teeth are minimally ground for this purpose. The advantage here is that they are much thicker and therefore tooth impurities do not show through, which is the case with non-prepared veneers.
