Is this possible to remove a veneer without affecting the enamel';

ASA Rola,Replacing veneers several times should not cause any additional damage to your enamel, but I do wonder if the dentist has had to prep your teeth at all.  Prepping your teeth several times repeatedly can lead to sensitivity for extended periods of time.  I recommend talking to your dentist and possibly forming an agreement to allow you to wait a few months to get accustomed to the new look.  At the end of that 90 or 120 days, you and your dentist can reassess whether you want to make changes or not.  Sometimes, it takes a few months for patients to get accustomed to their new look.  Good luck and I hope this helps.

You can remove old veneers with minimal removal of natural tooth if they are done carefully.   I have also heard veneers can be removed with a laser by affecting the bond so that the only drilling will be to remove cement .i have not done this personally so I cannot say it works for sure , but I have removed many veneers and have done so without damaging the remaining tooth structure
