That has charcoal as well. Are you worried about it removing all your enamel? I use My Magic Mud paste, the powder a couple times a week. A fellow freeper pointed out that charcoal is too abrasive and will destroy enamel.
I’ve used it for many years and never a problem. It’s really helped with the plaque and gums. My hygienist looked it up and told me to keep using it. I also rinse with 1 teaspoon bleach in a cup of water every 2-3 days on the advice of my hygienist. My dental health has improved a lot.
