SCIENCE BACKED ORAL CARE

The Ingredient That's Changing Oral Care

What is Nano-Hydroxyapatite?

Nano-hydroxyapatite (nHA) is a naturally occurring mineral that makes up 97% of tooth enamel and 70% of dentin. This biocompatible compound works by remineralizing and repairing tooth enamel at the microscopic level.

Unlike fluoride, which creates a protective barrier, nano-hydroxyapatite actually integrates into your tooth structure, filling in microscopic defects and strengthening enamel from within. It's been used in Japanese oral care for over 40 years and is now gaining recognition worldwide as a safe, effective alternative to traditional fluoride treatments.

How Nano-Hydroxyapatite Works

Discover the science behind our hero ingredient

1

Binds to Weakened Enamel Surfaces

Nano-hydroxyapatite (nHa) particles are similar in structure to the mineral that makes up tooth enamel, allowing them to attach to areas of the tooth surface that experience everyday wear.

2

Fills Microscopic Imperfections

Because the particles are extremely small, they can settle into tiny surface irregularities and worn areas, helping smooth and reinforce the enamel surface over time.

3

Supports Enamel Strength

As these areas are reinforced, teeth may feel stronger and less reactive to temperature changes, supporting overall enamel integrity with regular use.

Nano-Hydroxyapatite vs Fluoride

While fluoride works by coating enamel, nHa integrates directly into tooth structure because your body recognizes it as natural tooth material. Both have research supporting their use, but we believe nHa's biocompatible approach represents the future of oral care. Talk to your dentist about which option makes sense for your needs

Benefits of nHa

Discover the science-backed advantages of nHa for your oral health

Nano-hydroxyapatite is chemically similar to the mineral that makes up tooth enamel, allowing it to rebuild and reinforce weakened areas at the surface of the tooth. With regular use, it helps restore mineral density and support stronger, more resilient enamel.

By filling in microscopic imperfections and exposed areas on the enamel surface, nano-hydroxyapatite can help block external stimuli. This process often leads to reduced sensitivity to hot, cold, and sweet foods over time.

Nano-hydroxyapatite is a biocompatible ingredient that mirrors natural tooth mineral, making it a popular fluoride-free alternative in modern oral care. It’s widely used in dental and medical applications around the world.

As enamel becomes smoother and more uniform, light reflects more evenly off the tooth surface, creating a naturally brighter appearance. This whitening effect comes from strengthening enamel rather than using harsh bleaching agents.

Why Does 10% Nano-Hydroxyapatite Matter?

The concentration of nHa+™ matters. Higher percentages deliver more effective results. Mouthology uses 10% nHa+™, significantly more than most competitors who use 2-3% or don't disclose their concentration at all.

Yes. Studies show nano-hydroxyapatite is just as effective at preventing cavities and remineralizing enamel as fluoride — it just works differently. Instead of creating a fluoride layer on your teeth, nHa is biocompatible and literally rebuilds enamel with the same mineral your teeth are already made of. Your body recognizes it and knows what to do with it.

Higher concentration = better results. 10% nHa is the optimal amount for adult teeth to get maximum remineralization and cavity protection. We use 5% in our kids' formula because it's perfect for developing teeth. Most "natural" toothpastes use way less (or none at all) and wonder why they don't work.

Most conventional toothpastes contain SLS (sodium lauryl sulfate), which irritates gums and causes canker sores, artificial sweeteners, and unnecessary additives that don't actually help your teeth. Fluoride works, but many people want to avoid it—especially kids, pregnant women, and anyone trying to reduce chemical exposure. We skip the junk and use ingredients that actually do something.

It can help restore your teeth's natural color by filling in microscopic scratches and imperfections on the enamel surface, which makes them look smoother and brighter. It's not a whitening agent like peroxide, but healthier enamel naturally looks better.

Nano-hydroxyapatite is actually great for sensitivity. It can fill in the microscopic tubules in your enamel that cause pain when exposed to hot, cold, or sweet foods. Most people notice less sensitivity within 2-3 weeks of consistent use.
