I used this in conjunction with the Prime Time Teeth Whitening Pen (see below) but it should work with any of the teeth whitening systems out there. Since I didn't do an independant test [using the pen without this pretreatment], I can't say how much of a difference it would make without it, but I must admit that the combination didn't cause the sensitivity that I've gotten from other teeth whitening products I've used in the past [strips, trays, etc]. It's an extra step to pre-treat, but it takes about thirty seconds to do, so it's not going to cost you much time. To minimize sensitivity and, according to the manufacturer, speed up the process, it's worth the small amount of extra work.
