I started with tray 1 of 10 (top and bottom) in July of this year. The first few days, it felt awkward. But, i quickly got used to it. Now I am on trays 7 of 10 and I am very pleased with the way my teeth are starting too look. I cannot wait until I can see the finished product in December! I have not had any issues during this process and would definitely recommend this treatment. I have posted a picture from the first week and a picture now (7 of 10). I will post a picture in December of my complete results. Updated on 24 Jan 2013: I'm a little late, but now i am posting a picture of the final results. What do you guys think????

I have always had VERY sensitive teeth and gums and so was anxious about trying Zoom after all the reviews I have read about pain. However, I did not experience ANY pain or discomfort during or after the Zoom treatment. The result was only a couple of shades brighter. I got a great price through Groupon.com. It certainly would not be worth regular price. Updated on 29 Jan 2011: Now that it has been a few months since my Zoom treatment, I can definitely say it was not worth it. Very little, if any, change in my teeth. No one noticed, including family members! My daughter had it done also, and her results were very poor. She had a couple of hours of "zingers" (pain), but I had none.
