We (mom & 3rd grader) have been using this toothpaste for just over a week, and our teeth feel good. Enamel issues run in the family, my kiddo got the worst of it, and we’re trying to help his teeth stay healthy. We both like the mint taste, (way better than the one for sensitive teeth his dentist recommended, or the prescription one that tasted like bad bubblegum, or the “natural” health store one that was a burning strong mint). Thank-you for a fluoride alternative re-mineralization option that makes our mouths happy!
