After reading the reviews on here I was very nervous about getting this procedure done. Two hours later I have still not experienced any of the "zingers" that people have talked about. Yes, it is a little uncomfortable sitting in all the gauze and padding, and I did drool all over myself but it was worth it to have my gums, lips and face protected. I also did not feeling any pain during the acutual whitening at all.
I am getting ready to have two veneers done and I felt this was necessary to achieve that perfect smile!
