10% Nano-Hydroxyapatite Toothpaste

Nano-hydroxyapatite (nHa) is a naturally occurring mineral that makes up 97% of your tooth enamel. Think of it as your teeth's favorite building block.

When you brush with nHa toothpaste, these tiny particles fill in microscopic cracks and weak spots in your enamel, essentially "remineralizing" and strengthening your teeth from the outside in. It's like giving your enamel a daily tune-up—repairing damage, reducing sensitivity, and keeping your teeth strong and healthy. Science-backed, dentist-loved, and (bonus) your body already knows exactly what to do with it.

Nano-hydroxyapatite (nHa) doesn’t just protect enamel, it rebuilds it. It’s the same mineral your teeth are made of, so instead of hardening enamel through a chemical reaction like fluoride, nHa fills in microscopic weak spots and integrates directly into the tooth surface. That means stronger, smoother enamel and effective cavity protection, without relying on fluoride.

Fluoride isn't ideal for everyone either. Many people prefer to avoid it due to ingestion concerns (especially for kids), sensitivity issues, or a desire for a gentler, fluoride-free routine. Nano-hydroxyapatite is biocompatible, safe if swallowed in small amounts, and well-tolerated by sensitive teeth and gums.

It’s not new or experimental. nHa has been used in professional dental care and consumer toothpaste in Japan for decades, with a growing body of research supporting its effectiveness.

In short: fluoride strengthens enamel from the outside. Nano-hydroxyapatite helps rebuild it, naturally.

Yes! In fact, we highly recommend it if you have sensitive teeth.

Nano-hydroxyapatite is gentle and actually helps by filling in those tiny tubules (microscopic holes) in your enamel that cause the "ouch" when you sip something cold. Unlike harsh whitening toothpastes that can make sensitivity worse, Mouthology soothes and protects while still giving you a brighter smile. It's a win-win.

10% is the concentration most supported by published research as optimal for daily oral care. Too little nHA has limited efficacy. Too much causes the particles to aggregate, which actually reduces performance. Unlike most brands that hide their nHA percentage, we use the full 10% and tell you exactly why.

Our nano-hydroxyapatite is rod-shaped, with an average size of 100nm. The rod morphology mimics the natural crystal structure of tooth enamel, which research suggests helps the particles integrate more effectively with your enamel surface compared to spherical particles. Think of it like puzzle pieces fitting together at a microscopic level.

Our formula works by filling in tiny microscopic imperfections on the enamel surface, which makes teeth appear smoother and brighter over time as the surface reflects light more evenly. Most people start noticing a difference within a few weeks of consistent twice-daily brushing. It is a gradual process rather than an overnight dramatic change, and there is no peroxide in our formula.

One tube is approximately a one-month supply with twice-daily brushing using a pea-sized amount. If you want to stock up, our 3-pack covers three months and our 6-pack covers six months at a savings of up to 30%.

Yes, completely safe. nHA works by supporting natural enamel specifically, so it will not remineralize or change the color of crowns or veneers. It can help protect the natural tooth structure around your dental work. As always, check with your dentist for personalized guidance if you have extensive dental work.

Our RDA is approximately 80, which falls in the low-to-medium abrasivity range. The FDA considers anything under 200 safe for daily use. At 80 we are strong enough to clean effectively while being gentle enough to use every day without worrying about enamel wear.
