Check out Purelee Naturals Remineralizing Tooth Powder. NO hydroxyapatite, NO baking soda, NO fluoride or any harmful ingredients and we DO use xylitol (although toxic dogs, it works wonders for the human mouth - and just keep your dog out of your tooth powder!). It's actually just 7 ingredients - bentonite clay and calcium carbonate to rebuild and remineralize and a mix of herbs to help with a wide range of issues from gingivitis, bad breath, pain and inflammation, bleeding, teeth sensitivity and so much more! We have adult and kid flavors (which are also safe for toddlers). #toothremineralization #fyp #toothpowderrecipe #herbaltoothpowder #reversecavities
