What a surprise the first time I used this powder! I had put off ordering it because the last tooth powder I used (made my another company) tasted awful! I used it because I just assumed it was supposed to be that awful, and it was worth the bad taste to get the result. So I reluctantly ordered your product, and when I first used it, I was so happily surprised. It made my mouth feel so fresh and clean. I used it once, but then I decided that I must not have used enough. Maybe you have to use more to make it taste bad? It still had a great taste and left a cool, clean feeling in my mouth. Thank you for always making such high quality products!
