Love it, I noticed remineralization.
I was a sceptical dental hygienist.  I have a few "watch" areas,  that i have been watching for a few years.  I have, and still do, use rx fluoride toothpaste. I added this paste into my routine of brushing and flossing and have noticed in my xrays that my "watch" areas are smaller.  I alternate use between rx and the nano hydroxyapatite and do not rinse after brushing.  I will be buying it again. It's worth the price if it helps remineralize my teeth!
