Although lumineers are thinner and often placed without preparing the tooth enamel, they have several significant disadvantages. For example, because of their minimal thickness (0.2-0.3 mm), they cannot help with the heavily stained teeth and are more prone to chipping and cracking. In addition, they are limited in shades, unlike veneers, which have 20 shades. And the price of lumineers is 30% higher.
