Zoom Whitening: Stories

I had the zoom process done this morning. Had I known the possible side effects prior to the treatment I probably would not have done it. I was not informed of the entire procedure and was told my teeth may be "sensitive" as the bleach was being applied. May I add that I have a very high tolerance for pain. About halfway through the first 15 minute session I experienced a sharp zinger, which was followed by several others. I was left to my own devices for the 15 minute process. When the dentist came back, I asked if this was a normal feeling and she said yes. Yikes, and I have to do this for 3 more sessions? I bit the bullet and went through the next 2 sessions with the same zingers as well as my lips having a burning sensation. 3 minutes into the 4th and final session, somebody pulled the cord out of the power and I waited for 5 minutes for them to try and get the light to work again. I finally said I'm done and had them remove the mouth piece and bleach gel.It has now been about 8 hours and I am still feeling the zingers, not so often but the pain is quite excrucuating. I had to take a vicodan which helped, but the zingers are still there. My lips are a bit burned but that is bearable. My teeth are beautiful... would I do it again? Never. I'll stick to Crest whitening strips.
