Our take
Why We Flagged It
Uncle Harry's uses a short, mineral-based, fluoride-free and SLS-free formula and has been family-run since 1991, with no corporate parent. But its toothpastes carry a California Prop 65 warning for lead, which the maker links to its bentonite clay. That lands on our heavy-metal axis, so we flag it rather than badge it clean. Read the alert first.

What's inside
Ingredients & Safety
Mineral clays, sea salt, and ionic minerals with calcium, magnesium, and phosphorus, plus colloidal silver and a blend of peppermint, eucalyptus, clove, and wintergreen essential oils. No fluoride, SLS, or synthetic sweeteners. The maker says its bentonite clay contains naturally occurring trace minerals, including lead, which is why the toothpastes carry a California Prop 65 warning (see the alert).
