Zoom Whitening Pain

I am shocked there are dentists on here saying it is safe and painless. They clearly have not done this treatment on themselves- which they should do if they are going to make such claims. If they are not brave enough to do this themselves, they should research what people are saying all over the internet. Zoom is TERRIBLY PAINFUL for many, many people- not just a few. I did Zoom whitening yesterday. It was HORRIFIC. My dentist said absolutely NOTHING about the possibility of pain with this treatment. Everything was fine at first. The doctor took a picture of my teeth prior to starting. She painstakingly covered every part of soft tissue, leaving only my teeth exposed. She told me we were going to do three 15 minute treatments. The first one was fine. During the second one, my gums started burning slightly, and I began getting sharp shooting pains in my teeth. It was like someone was poking an exposed nerve in my tooth with a pin. I couldn't WAIT for the 15 minutes to be over. It got progressively worse through that session and when it was over I told the dentist that I would absolutely NOT do the third treatment. I really felt that it was doing SERIOUS DAMAGE to my teeth. When she removed all the stuff, she put vitamin E on my gums and Flouride on my teeth to "relieve the sensitivity" but that didn't work at all. She told me to rinse, and I was so terrified to put even a small amount of water near my teeth! I was VERY VERY upset and angry that she had not warned me, and I told her. She took an "after" picture and showed me the before picture, and I told her I saw no difference at all- which was true (to be fair I only did 2/3 of the treatment). She started telling me about the at home part of the treatment and I told her I would absolutely NOT be putting anything related to Zoom near my teeth ever again. Thankfully, she did not charge me because if she did I would have had a fit. I walked out of there very upset and in A LOT OF PAIN. Now it is 24 hours later and my gums are terribly sore and my teeth are extremely sensitive and the sharp pains continue. I have never had sensitive teeth before, and I have a high pain tolerance. In addition, my sense of taste has been affected. Things don't taste right! I really, really hope these negative side-effects go away quickly. In my opinion, Zoom is VERY BAD for your teeth and could likely do lasting damage. I recommend you find an alternative to whitening your teeth, and stay far away from this procedure. It is a nightmare.
