What's the difference betweeen Lumineers and veneers? What gives the whitest teeth of the two?

Hi:Lumineers requires very little to no preparation of the tooth and veneer requires preparation of the tooth.  In my experience if the teeth are in proper position, lumineers can make the teeth look too wide and too far forward.  However if the teeth need to be built out lumineer is a very good option.  Normally with veneers you can make the teeth much whiter due to having thicker porcelain.Best,Dr. Maddahi

Hello there,
Lumineers and traditional veneers can both get you white teeth.  The major difference is lumineers go over the teeth with little to no tooth preparation whereas veneers require some tooth modification but are much more versatile.  Choosing the right situation is critical for lumineers to look good and appear natural.  If lumineers are done on the wrong type of smile, they can easily appear too big, bulky and or opaque. Traditional veneers have much more flexibility in what they can achieve.
It's also very important to understand how "white" you want your teeth.  Too white will look fake with either lumineers or traditional veneers.  I would recommend closely examining before and after pictures of the doctor's actual patients, checking for color, shape, size, and translucency. Ask to see specific examples of lumineers vs traditional veneers before making any decision of how white to go and which type of veneer. Good luck!
