Heljam, it's good that it worked for you, 2 reasons for this comment: 1. You were one of the lucky ones. Many people have severe, LASTING pain. You can't assume that other people's teeth will respond the same way, even if the procedure is done exactly the same way by the same person. You also have no way of knowing ahead of time whether your pain will last a few hours or a year, or more. Cost has nothing to do with it, some of the $400 providers are more skilled and more careful than some of the $1200 providers. 2. The question of whether the same whitening results as Zoom can be obtained with less risk deserves a lot more attention. There are other ways to bleach teeth, even stubborn teeth, with the same(or better) results,and with much less risk. It takes a bit more time, is all......
