Toothpaste with micro natural hydroxyapatite and ozonated oil: the natural alternative to fluorine

Hydroxyapatite in Toothpaste: A Natural and Effective Alternative to Fluoride

Choosing the right toothpaste is no longer just about flavor or freshness. Today, consumers are looking for healthier, more natural, and above all effective solutions to protect their teeth. While fluoride has long been the reference ingredient, its use is increasingly debated.

In this context, hydroxyapatite, a mineral naturally present in enamel and dentin, has emerged as a credible alternative. However, not all hydroxyapatites are the same: should one choose micro-sized hydroxyapatite from natural sources or nano-sized hydroxyapatite of synthetic origin? And what added value does the innovative combination of micro-hydroxyapatite with ozonated oil bring?

This article offers an in-depth guide to the world of hydroxyapatite toothpastes.

What Is Hydroxyapatite?

A Natural Component of Our Teeth

Hydroxyapatite is a calcium phosphate that makes up more than 90% of tooth enamel and around 70% of dentin. It is responsible for the hardness and resistance of our teeth, enabling them to withstand daily mechanical and chemical challenges.

A Biomimetic Ingredient

When used in toothpaste, hydroxyapatite has the unique ability to mimic the structure of enamel and fill micro-cracks on the tooth surface. It also promotes remineralization and reduces tooth sensitivity. Unlike fluoride, which mainly acts by forming a chemical protective layer, hydroxyapatite physically and directly rebuilds the tooth surface.

Micro vs. Nano Hydroxyapatite: What’s the Difference?

Synthetic Nano-Hydroxyapatite

Produced in laboratories, with extremely fine particles (< 100 nm).

Excellent ability to penetrate micro-defects in enamel.

However: costly manufacturing, non-natural origin, and persistent concerns regarding the safety of repeated exposure to nanoparticles in the oral cavity.

European regulations require specific labeling for nano-form ingredients, reflecting heightened regulatory caution.

Naturally Sourced Micro-Hydroxyapatite

Extracted from natural sources (e.g., bio-mineral apatite).

Particle size closer to the natural structure of enamel (greater than 100 nm).

Lower risk of undesirable penetration into the body.

More respectful of the biological balance of the oral cavity.

Proven remineralizing effect comparable or even superior to fluoride in the long term.

👉 In summary: naturally sourced micro-hydroxyapatite offers a safer, more ecological, and better-tolerated profile while maintaining remarkable effectiveness.

Comparative studies already show that hydroxyapatite can provide remineralization equivalent to that of fluoride toothpastes. For example, Tschoppe et al. demonstrated that hydroxyapatite-based toothpastes remineralize enamel lesions as effectively as fluoride toothpastes (Tschoppe et al., 2011).

Benefits of Micro-Hydroxyapatite Toothpastes

Natural Remineralization

By binding directly to enamel, hydroxyapatite fills weakened areas and strengthens the tooth structure.

Reduction of Tooth Sensitivity

By occluding exposed dentinal tubules, it acts as a natural “mineral bandage” against pain associated with sensitive teeth.

Protection Against Cavities

Unlike fluoride, which works by making enamel more resistant to acid, hydroxyapatite actively repairs the tooth surface and limits bacterial adhesion.

Whiteness and Shine

Its gentle mechanical action helps remove superficial stains without damaging enamel, contributing to a naturally brighter smile.

A clinical study conducted by Najibfard et al. confirmed that regular use of a hydroxyapatite toothpaste reduces the progression of early carious lesions and promotes remineralization, with results comparable to fluoride toothpastes (Najibfard et al., 2011).

The Innovation: Micro-Hydroxyapatite + Ozonated Oil

What Is Ozonated Oil?

It is a vegetable oil, often olive oil, enriched with ozone. Ozone, known for its strong oxidative properties, is stabilized within the oil and releases antimicrobial and healing effects.

Benefits of the Synergy

Reparative action: micro-hydroxyapatite rebuilds and strengthens enamel.

Sanitizing action: ozonated oil reduces bacterial load, balances the oral microbiome, and promotes gum healing.

Anti-inflammatory action: it soothes sensitive gums or gums prone to bleeding.

Double protection: lower risk of cavities, reduced inflammation, and improved overall oral health.

A Smart Alternative to Fluoride Toothpastes

No risk of overdosing: unlike fluoride, which may cause fluorosis in cases of excessive intake.

Suitable for everyone: children, adults, pregnant women, and individuals sensitive to fluoride.

Holistic approach: acts simultaneously on teeth and the oral environment (enamel + gums + microbiome).

The effectiveness of ozonated oil in oral wound healing has been demonstrated, notably in a study showing significant improvement in palatal wound healing after gingival graft procedures (Ozdemir et al., 2013). When combined with micro-hydroxyapatite, it provides a dual action: remineralization + sanitization.

Why Choose a Toothpaste with Micro-Hydroxyapatite and Ozonated Oil?

For Safety

No nanoparticles, no potentially toxic fluoride.

For Comprehensive Effectiveness

A formulation that is simultaneously reconstructive, protective, and antibacterial.

For Naturalness

Naturally sourced ingredients that respect both the body and the environment.

For the Future of Preventive Dentistry

Research indicates that these formulations represent a promising path forward, combining proven efficacy with long-term safety.

Conclusion

Hydroxyapatite marks a turning point in oral hygiene. However, it is essential to distinguish naturally sourced micro-hydroxyapatite safe and biomimetic from synthetic nano-hydroxyapatite, whose safety profile remains debated.

When combined with ozonated oil, micro-hydroxyapatite offers a comprehensive solution: it remineralizes, protects, sanitizes, and soothes.

Toothpastes based on this synergy, such as Ozonic by Aquolab, represent a modern and natural alternative to fluoride toothpastes suitable for the whole family and respectful of long-term health.

By choosing this new generation of dental care, you opt for a healthy, protected, and radiant mouth while avoiding the risks associated with fluoride and nanoparticles.
