Can Lumineers be removed without any other procedures required?

Yes, Lumineers can be removed.  You should seek a cosmetic dentist that will be able to remove the Lumineers without damaging your underlying teeth.  After removal, your teeth will need to be polished, but more prepping will not be required.  I always tell patients that porcelain veneers are so much better than veneers for most cases.  Lumineers require no prep, so they look bulky and can often times pop off.  Porcelain veneers don't look bulky (if done properly) and are very permanent.  Hope this helps.Dr. Sarah ThompsonSaint Louis, MO  and OFallon, IL

If your dentist removed some teeth structure prior to placing your Lumineers, then you’ll need other procedures to restore those teeth shapes. If your case was truly “NO PREP” which means your dentist really did NOT grind on your teeth, then removing your Lumineers will uncover your natural original teeth shapes. Only your dentist will know. The fact that he is reluctant to remove them, I have a hunch that he had forums your teeth a bit.

Lumineers can be removed without damaging teeth, however, the question is why are you removing them? If you are unahppy with your smile, keeping the Lumineers won't change anything, and removing them won't improve your smile. Perhaps before you remove them, you should have a smile design and a plan for replacing them. 
Best,
