Hi D!
Oh my gosh the ZOOM hurts like heck!! I am like Renee, my teeth aren't overly sensitive, but they started getting jolts of pain through the procedure and I literally thought I was going to pass out from it. They continued for a few hours afterwards too. I would NEVER do this again! I paid about $600 for mine and my teeth look great now but not worth that pain. Not at all!! They give you trays and a supply of whitening stuff to use over time afterwards, but even those hurt me now too. They tell you to leave them in for an hour but I can only do 30 minutes. And I'm scared to do the day and night together in the same day. If I do, it's several days or even weeks before I can use them again. I've never been this sensitive to anything.
My husband just got the trays after his cleaning and they made a big difference on him too. That's what I'd stick with if I were you!!
Plus, when I had mine done we didn't realize quite yet that the inside of my mouth is most likely allergic to latex. Each time I go for a cleaning or anything, ulcers pop up in my mouth. Anyway, when you do ZOOM, they put an ointment on your lips and cover them with foil. Mine weren't covered well enough and they burned during the treatment. My lips were so blistered for nearly two weeks, plus the ulcers and the jolting pains through my teeth. I was so pissed that I couldn't even enjoy my new white teeth for 2 weeks, I couldn't even smile because it was so painful.
Bottom line - save your money and just go with the trays!
