Bests & Worsts Reviews from Amazon

My front teeth have been somewhat translucent for a while and after putting this on ONCE before bed and it's effectively gone. Blew my mind when I looked in the mirror this morning. still hurt sensitive teeth: My front bottom teeth have always been extremely sensitive to whitening strips to the point where I've stopped using them (searing sharp pain on the tip of the tooth). This product is so much better, but I've still felt that sharp searing pain on those teeth. The difference is that now it only happens for a fraction of a second, versus the constant pain from the strips.
