Title: Works great, but OUCH!
Review: OUCH! Literally, the MOST intense pain that I have ever experienced. As irrational as it may sound, I'd trade for a broken arm at times when the pain was beyond excruciating.The gel itself definitely does a good job (actually, a great job) whitening your teeth - no question. However, it comes at a high price - pain, pain, and more pain. Initially, I was under the impression that the pain would go away. When I woke up, the pain was even more agonizing. No, wait... I didn't have to wake up! I never fell asleep.I have semi-sensitive teeth - really nothing out of the ordinary. I would not recommend this product, UNLESS you plan on taking some sort of a pain killer prior to its use. That, or some morphine - I am NOT kidding. Currently, I am stuck with 8 unused surringes, so I'm seriously considering my own proposal.These are 20% peroxide, which may explain the extreme discomfort. Perhaps the 15% (or less) will hurt less.
