Can composite resin veneers be removed without any damage or discoloration to original tooth structure and enamel? (Photo)

I had gotten composite resin bonding in the form of veneers (in that the bonding was added to front along with the sides of the tooth) over 2 months ago. I was given 2 shots to each of my lateral incisors as the dentist said he was going under my gums. The dentist told me he was not going to drill and was going to try to be as conservative as possible. Can the veneers be removed without damage or discoloration to the original teeth? And are there any permanent side effects of this procedure?
