Hydroxyapatite (HA) is a naturally occurring mineral that makes up most of tooth enamel , bones, and all hard structures in the body. Due to its natural and biocompatible properties, HA is now recognized as a safe and effective alternative to fluoride to aid tooth remineralisation.

Simply put, Hydroxyapatite is a natural form of calcium that works to keep teeth strong, healthy, and protected from everyday wear.

⭐ Benefits of Hydroxyapatite for Teeth

Hydroxyapatite provides many important benefits for oral health, including:

✔ 1. Remineralize Teeth

Helps repair minerals lost in enamel due to acidic foods, plaque, or the habit of brushing teeth too hard.

✔ 2. Strengthens Enamel

Rebuilds and reinforces the outer protective layer of the teeth, making them more resistant to damage.

✔ 3. Makes Teeth Brighter Naturally

By filling microscopic surface defects, teeth appear smoother and brighter—without harsh bleaching agents.

Nano-Hydroxyapatite in Toothpaste: Safe Guide for Family

In 2021, the European Union (EU) reviewed the safety of nano-hydroxyapatite (n-HA) in oral care products. This review was prompted by the increasing presence of low-cost, needle-shaped nano particles entering the market.

Scientific discussions at the time raised concerns that certain needle-like crystallites could potentially penetrate soft tissue, accumulate in organs, and migrate within the body. Importantly, these concerns were not about hydroxyapatite as a substance, but about specific particle shapes, sizes, and manufacturing quality.

EU Regulatory Update: What Changed in 2024?

Following further scientific evaluation, the EU revised its position in 2024.
Under the updated regulation—effective November 2025—the use of rod-shaped nano-hydroxyapatite is permitted in oral care products within defined safety limits.

This non-needle form has been assessed and considered safe for oral use, clearly distinguishing it from the earlier concerns associated with needle-shaped particles.

Why Particle Type Matters

Not all nano-hydroxyapatite is the same.

Differences in particle shape, size, and source can influence how a material behaves in the body. This is especially important for products used daily, including toothpaste for families, children, and teens.

What About Other Regulatory Bodies?

As of now, authorities such as the FDA (United States) and BPOM (Indonesia) have not issued specific classifications or rulings on nano-hydroxyapatite particle types in oral care.

However, the EU’s review highlights the importance of ingredient transparency and informed consumer choice.

Hydroxyapatite in Grants Whitening + HA Toothpaste

Grants Whitening + HA uses non-nano hydroxyapatite (also called micro hydroxyapatite), sourced from natural minerals rather than nano hydroxyapatite which is generally synthetic, meaning it's manufactured in a lab to be extremely small (nanoscale) and therefore at a much cheaper cost.

Key Features:

• 🌿 Derived from natural mineral sources

• 💚 Hypoallergenic

• 🌱 Non-GMO

• 🐰 Vegan-friendly

• 🔬 Uses non-nano (micro) hydroxyapatite, not synthetic nano particles

🔍 Non-Nano (Micro) Hydroxyapatite: How It Works & Benefits

Non-nano hydroxyapatite works primarily on the surface of tooth enamel. While its particles are larger than nano hydroxyapatite and do not penetrate as deeply, it remains highly effective—and ideal for daily oral care.

How It Protects Teeth:

• Repairs tiny surface scratches in enamel

• Forms a protective mineral layer on teeth

• Strengthens weakened enamel

• Helps protect against everyday enamel wear

Non-nano hydroxyapatite is naturally derived from calcium carbonate (limestone) and phosphate minerals, making it gentle and well-tolerated.

⚖️ Difference between Non-Nano Hydroxyapatite vs Nano Hydroxyapatite

Conclusion:
Non-nano hydroxyapatite is a more natural, safer, and more effective option for daily use - especially for those looking for a fluoride alternative.

• children (under adult supervision)

• those of you who want natural toothpaste but still effective for remineralisation

• those of you who avoid fluoride but still need remineralization

🦷 Conclusion: Why is Choosing Hydroxyapatite Important?

Hydroxyapatite — especially the non-nano version — is a natural ingredient that has been shown to help:

• strengthen enamel

• repair micro damage

• keep teeth bright

• provides safe daily protection

Clear labeling, responsible formulation, and transparent ingredient sourcing empower families to make confident decisions about their oral health.
