A luxury fluoride-free tooth powder, hand-finished in small batches. Seven ingredients, each traceable to a single origin, and nothing else.
Micro-crystalline hydroxyapatite is the mineral your enamel is made of, and it has been studied for enamel remineralization. Organic Finnish birch xylitol works against the bacteria that feed on sugar. Georgia kaolin clay lifts coffee and wine stains gently, without wearing enamel down.
Amabito no Moshio sea salt from Hiroshima, Italian peppermint oil, Indian spearmint, and organic menthol crystals finish it with trace minerals and a cool freshness that lasts.
Every origin: kaolin clay (Georgia, USA), birch xylitol (Finland), micro-crystalline hydroxyapatite (New Zealand), Amabito no Moshio sea salt (Hiroshima, Japan), peppermint (Italy), spearmint (India), menthol (India).
Each 35 gram jar lasts five weeks on average with twice-daily brushing. Wet your brush, dip, and brush gently for two minutes. Free U.S. shipping. The One Jar Guarantee.

No filler, no anonymous 'natural flavors.' Every ingredient here has a job: to remineralize, protect, polish, or freshen. And each is sourced from the one place in the world that does it best.
It's the same mineral your tooth enamel is made of. Hydroxyapatite has been studied for enamel remineralization, and it is the fluoride-free ingredient at the heart of the formula.
We source ours from New Zealand, where BSE-free, pasture-raised herds set the world standard for clean bovine hydroxyapatite. At 15%, we load it heavy, because it's the ingredient that does the work.
Xylitol starves the bacteria that feed on sugar and helps keep your mouth's pH in balance. Dentists have recommended it for decades.
Finnish birch, never corn-derived. It's the real thing, and it's what makes the powder taste clean instead of chalky.
The gentlest polishing clay there is. It lifts surface stains from coffee, wine, and tea for a naturally brighter smile, without the harsh abrasives that wear enamel down.
Georgia white kaolin, prized for its fineness: clean teeth, zero scratching.
Trace minerals that support a healthy mouth environment. Nothing stripped, nothing synthetic.
A 2,500-year-old seaweed salt, still hand-made on a tiny island in Japan's Seto Inland Sea. One of the rarest salts on earth.
A bright, cooling mint flavor that makes brushing something you look forward to. Never a synthetic "mint flavor" cover-up.
Steam-distilled peppermint from Italy's Piedmont hills. The real thing, not a lab-made flavor: the taste, done honestly.
A softer, sweeter mint that rounds out the sharper peppermint. It keeps the finish fresh and green rather than harsh.
Grown in India, where the warm climate gives spearmint a fuller, greener aroma. A small amount balances the whole blend.
A clean, cooling freshness that actually lasts through the day, not the quick fade most powders give you.
Organic menthol crystals, plant-derived from mint. The reason your mouth still feels fresh hours later.

Read the full guaranteeIn an 18-month randomized controlled trial, a 10% hydroxyapatite toothpaste performed comparably to fluoride in remineralizing early enamel lesions.
A 2019 clinical study in BDJ Open found hydroxyapatite toothpaste remineralized initial caries lesions and performed as well as fluoride.
Crown is made with 15% microcrystalline hydroxyapatite, the same mineral your enamel is made of, at a higher concentration than the products studied above.
