Ordinary veneers have a minimum thickness of 0.5mm, while Lumineers® can be as thin as 0.2­–0.3mm. The difference may seem insignificant, but it actually makes a huge difference when it comes to the look of your teeth. Even just a few too many fractions of a millimeter added to your teeth can create an awkward, artificial-looking smile. This is why dentists have to shave down a tooth before it can get a veneer. Because they are smaller than regular veneers, Lumineers® reduce or eliminate the likelihood of an unnatural look.
