Bests & Worsts Reviews from Amazon

This worked for me; after years of bleaching my teeth, almost overnight they became almost transparent - this product, after only a few days' use, is beginning to reverse that. (I looked online for all the scientific research to vet this - and was satisfied with what I found there). This is not a paid endorsement, nor did I receive a free sample, and I am writing this as I have found sometimes that the high number of reviews don't accurately reflect the product here. In my case, with this item, my review means it works for me, and I will be buying this in bulk. (There is xylitol in it, if that matters to the reader).
