It does not require any tooth preparation such as drilling or anesthetic injections like with normal veneers. With regular porcelain veneers the dentist will have to strip away some of the front of the tooth – about as much as the thickness of the veneer he or she is going to place. With Lumineers this is not necessary as they are so thin (generally only about .2 to .3mm thick) that they can be bonded directly onto your teeth. Your existing teeth will therefore remain intact when Lumineers are going to be placed.
Lumineers are semi-transparent and make your teeth look whiter – an advantage that you don’t have with normal veneers.
