Product details
A mineral tooth powder built around 10% hydroxyapatite with calcium carbonate, xylitol, bentonite clay and spearmint & wintergreen leaf oils. 60g per jar — about 3 months of twice-daily brushing. No fluoride, no SLS, no foaming agents, no artificial sweeteners, vegan.
How to use
Wet your toothbrush, tap off excess water and dip the bristles into the powder (or use the scoop). Brush gently for two minutes, spit, and — for best results — don't rinse straight away, so the minerals keep working. Use morning and night like normal toothpaste.
Ingredients
Hydroxyapatite (10%) — the enamel mineral, supports daily remineralization. Calcium carbonate — gentle mineral polish. Xylitol — supports a healthy oral pH. Bentonite clay — draws out impurities. Spearmint & wintergreen leaf oils — natural freshness and gum comfort. Nothing else.
The old way vs the new way of brushing
Stronger teeth. Gentler care.

A fluoride-free upgrade that supports real enamel strength.

Most toothpaste cleans the surface and stops there. This powder is built to give your enamel back the minerals it loses every day — with nothing your mouth doesn't need.

Whitens without harsh chemicals

Lifts surface stains for a naturally brighter smile — no bleach, no burning, no aggressive abrasives.

Supports enamel where it matters

Hydroxyapatite — the mineral enamel is made of — helps keep tooth surfaces smooth and resilient with daily use.

Comfort for sensitive teeth

Fluoride-free and foam-free, designed for daily use without irritation or zingy aftershocks.

Supports gum health

Soothing botanicals and essential oils help keep your whole mouth balanced and fresh.

Clean, safe ingredients

Powered by nature. Proven by minerals.

Every jar is a short list of things your teeth actually recognise — and nothing else. No fluoride, no SLS, no foam, no fillers, no animal-based ingredients.

No fluoride required — how hydroxyapatite works
Mineral-first oral care

Your enamel doesn't need chemicals. It needs its mineral back.

Enamel is roughly 96% hydroxyapatite — and it loses a little of it every day to acids, coffee and wear. This powder simply gives it back. That's the whole idea: oral care that strengthens and balances your smile instead of overwhelming it.

Recognised, not tolerated

Hydroxyapatite bonds to enamel because it is enamel — no foreign chemistry required.

Safe for the whole family

Fluoride-free and safe to swallow in normal brushing amounts — kids included.

Third-party tested

Every batch is tested for safety and purity before it ships.

Blending the MoonWhite mineral formula Small-batch blended
Mineral-focused. Built for long-term oral health.

We didn't want a softer toothpaste. We wanted a smarter one.

MoonWhite started with a simple frustration: almost everything on the toothpaste shelf is built around foam, flavour and fluoride — and almost nothing is built around the mineral your teeth are actually made of.

So we went the other way. We stripped the formula down to what enamel recognises: 10% hydroxyapatite for daily remineralization, calcium carbonate to polish, xylitol for pH balance, bentonite clay to draw out impurities, and real mint oils for freshness. No SLS, no foaming agents, no fillers, no artificial anything.

Every batch is third-party tested for safety and purity before it ships. When you brush with this powder, you're not tolerating a compromise — you're giving your enamel back what daily life takes out of it.

The MoonWhite Formulation Team Oral care, mineral-first — since day one.

Dentist-Developed. Mineral-Focused. Built for Long-Term Oral Health.

Dr. Michelle Jorgensen is a practicing dentist who has spent years researching safer, more effective alternatives to conventional dental products.

After experiencing health challenges linked to traditional dental materials, she became deeply committed to creating fluoride-free, mineral-based solutions that support both oral health and overall wellness.

Her remineralizing tooth powder was developed using hydroxyapatite — the same mineral found in natural tooth enamel — to provide daily enamel support without harsh chemicals, synthetic foaming agents, or unnecessary fillers.

This hydroxyapatite tooth powder reflects her philosophy: oral care should strengthen, balance, and support your smile — not overwhelm it with aggressive ingredients.

When you use this formula, you're not just choosing a natural product — you're choosing a dentist-developed approach rooted in mineral science and long-term care.

"I work in a dental office and I'm picky. This feels effective without all the junk that's in most paste — my teeth feel genuinely smooth after brushing."

Denise · Dental hygienist

"A few weeks in and my teeth feel stronger and much less sensitive. My husband noticed the difference before I even told him what I'd changed."

Susan

"Took two brushes to get used to powder instead of paste. Now regular toothpaste feels like soap to me. The whole family switched."

Kolbie

"Teeth feel smoother, look whiter, and my morning breath situation has honestly improved. Recommended it to my mom and two friends already."

John

"My dentist pointed out two soft spots in spring and wanted to keep an eye on them. At my autumn cleaning she asked what I'd been doing differently. This powder is the only thing I changed."

Marianne

"Cold water used to make me wince. Three weeks of brushing with this and I'm drinking iced coffee like a normal person again."

Priya

"Two cups of coffee a day for fifteen years — my teeth looked it. The surface stains have faded noticeably and nothing about it feels harsh."

Marcus
★★★★☆Verified

"The powder format takes getting used to and there's no foam, which felt strange the first week. But my teeth have honestly never felt cleaner, so I'm staying."

Hannah

"I've tried three hydroxyapatite pastes and they were all mostly water and thickener. This is the first one that's actually 10% and you can tell."

Alex

"The jar looked small so I was skeptical about the three-month claim. Ten weeks of twice-daily brushing later, I'm barely halfway through."

Grace

Backed by research

Hydroxyapatite is one of the most-studied minerals in dentistry.

Peer-reviewed studies have compared hydroxyapatite head-to-head with fluoride for remineralization, sensitivity and daily use — here is a selection:

  • Amaechi et al., "Comparison of hydroxyapatite and fluoride oral care gels for remineralization of initial caries: a pH-cycling study", BDJ Open, 2020.
  • Paszynska et al., "Impact of a toothpaste with microcrystalline hydroxyapatite on the occurrence of early childhood caries: a 1-year randomized clinical trial", Scientific Reports, 2021.
  • Tschoppe et al., "Enamel and dentine remineralization by nano-hydroxyapatite toothpastes", Journal of Dentistry, 2011.
  • Steinert et al., "Daily application of a toothpaste with biomimetic hydroxyapatite and its subjective impact on dentin hypersensitivity, tooth smoothness, tooth whitening, gum bleeding and freshness", Biomimetics, 2020.
  • Harks et al., "Impact of the daily use of a microcrystal hydroxyapatite dentifrice on de novo plaque formation and clinical/microbiological parameters of periodontal health", PLoS ONE, 2016.
  • Niwa et al., "Polishing and whitening properties of toothpaste containing hydroxyapatite", Journal of Materials Science: Materials in Medicine, 2001.

Questions, answered.

How does the powder help my teeth?
Enamel loses minerals every day. The 10% hydroxyapatite in this powder is the same mineral your enamel is made of — brushing with it supports daily remineralization, helps smooth the surface, and reduces sensitivity over time.
What does it taste like?
Cool mint — from real spearmint and wintergreen leaf oils. No artificial sweeteners, so it tastes cleaner and less "candy-like" than regular paste.
How long does one jar last?
Each 60g jar lasts about 3 months with twice-daily brushing — a little powder goes a long way.
How do I use it?
Dip a damp toothbrush into the powder, brush for two minutes, spit. For best results, skip the immediate rinse so the minerals stay on your teeth longer.
Is it safe to swallow?
Yes — the formula is fluoride-free and made from food-grade minerals and botanicals, so normal brushing amounts are safe to swallow. That also makes it a good option for kids.
Can I use it during pregnancy?
The ingredient list is short, natural and fluoride-free. As with any product change during pregnancy, check with your doctor — but there's nothing harsh or synthetic in the jar.
Is it safe with crowns and veneers?
Yes. The powder is low-abrasion and polishes gently, so it's safe for crowns, veneers and bonding. (It remineralizes natural enamel — restorations simply get a gentle clean.)
How often should I use it?
Twice a day, in place of your regular toothpaste. Consistency is what drives remineralization.
How much hydroxyapatite is in it?
10% — the concentration used in most published remineralization research.
What if it's not for me?
