Can Veneers Be Taken off if I Want Them Removed?

If you were deem a great candidate for Lumineers ("no prep"), then yes, you can choose to have the Lumineers removed and return to your old self.  If you chose and end up with traditional veneer where the dentist ground and shaved your natural teeth away to place the traditional veneers, then no, your old teeth shape is no longer there.  Lumineers can be reversible where traditional veneers are not.

Typically if you get veneers, your dentist will reshape your teeth.  In that case, if you need to change veneers, you can't go back to your old smile.  Incase you are a candidate for a no prep veneers, then it is easier to go back to your old teeth.  However, do your research, find a great cosmetic dentist that can show you thier before and after pics and enjoy your new smile.
