When the people at Grind Oral Care (a U.S. Veteran owned business 
) reached out to me to give their activated charcoal whitening toothpaste a whirl, you better believe I said, “absolutely!” 
First it’s cruelty free AND vegan. No animal testing here! 
It’s free of those gross “weak” ingredients. That means it’s FREE of SLS, SLES, DEA. sulfates, triclosan, dyes, peroxide, paragons, artificial flavors, artificial flavors, sweeteners, and gluten. BPA free too. In addition to the activated charcoal it also contains two remineralization ingredients to help strengthen enamel including: Hydroxyapatite (a natural mineral) and Theobromine (a Cacao extract). Did I mention it’s made in the U.S.A.?
Here’s why I love it… it tastes great. A really beautiful mint flavor that’s not under or over powering. NO mess — the powders can be a challenge because they get everywhere. Mr. HW loves it (he’s fussy so it’s a rare occurrence that he likes anything out of his routine). Budget friendly. AND, it works. 
It gets the approval of a fussy husband, cranky teen, a vain teen and a mom trying to navigate it all. 
Brush like you want it. Spit like you mean it. You won’t be disappointed. —-> https://amzn.to/3FeGbOr
