I had Zoom Whitening performed in 2003 and regret having it done. First of all the advertisements about being able to get it done during your lunch hour were false, my session took about 3.5 hours. Secondly, the technician applied so much peroxide gel along my gum line that it actually blistered my gums and has caused gum damage in the areas that were most blistered and burned. The results don't last long at all if you have anything more than surface staining from caffeine, etc on your teeth. If your teeth are off-color under the enamel, from antibiotics, etc, the effects of the zoom whitening do not last. I think there are other alternatives that are much more effective than the Zoom Whitening

The dentist I used was more interested in trying to sell me other services. I was planning on switching to him as my old dentist was retiring but after my experience with him and my son's experience I decided he was running a racket of some sort and decided to stay well away. There was definitely a lot of bait and switch antics going on and I later found out that some of the "required" work on my son that was not covered by our dental insurance was something he had been doing to about 70% of other adolescent patients...conning parents to remove old fillings by stating that the materials used were subpar or harmful and then applying new ones which were not covered by insurance since the same teeth were being refilled. I found one mother in my son's school that said she didn't even think he had really removed her child's old fillings but rather left them in and claimed to have remove and refilled. He definitely needs to be investigated for fraud.
