Hydroxyapatite in dental care: 5 things you should know
Hydroxyapatite is becoming increasingly important in modern oral care. But with all the attention surrounding nano-hydroxyapatite (nHAp), many people are asking themselves: how safe is this ingredient really? And what should you look out for?
At Dentafari, we don't rely on nano, but on highly pure, functionalized hydroxyapatite in a unique composition - for maximum effect without risk. In this article, we show you the five most important facts about HAp - and why we deliberately avoid nano.
Nano is not always better - why we don't use nano HAp
Although nano-hydroxyapatite is celebrated as an innovation in dental cosmetics, European authorities take a different view. The EU is planning to ban nano-hydroxyapatite in dental care products from February 2025 if certain safety requirements are not met. The reason: there is a potential for toxicity, particularly in the case of needle-shaped or irregularly shaped particles, which are often found in cheap raw materials. The long-term effects of such nanomaterials on the body have not yet been sufficiently researched.
➡️ That is why we at Dentafari use non-nano HAp with a specially developed surface and high porosity - completely safe, biocompatible and EU-compliant.
Our HAp is superior to natural tooth enamel
Hydroxyapatite is not a foreign substance - it makes up around 97% of natural tooth enamel. The HAp we use is obtained by recrystallization from high-purity calcium carbonate. What makes it so special?
- Ideal calcium-phosphate ratio for effective remineralization
- Porous structure that releases active ingredients more quickly
- Smoothing and whitening of the tooth surface
- No nanoparticles, no risks
💡 Why is Dentafari HAp more effective than conventional micro- or nano-HAp?
The effect of hydroxyapatite in dental care depends not only on the raw material, but above all on how well the important minerals calcium and phosphate are released. These two minerals are crucial for the remineralization of tooth enamel.
🔍 And this is precisely where the strength of our HAp comes into play:
Better calcium-phosphate ratio
Saliva normally contains more phosphate than calcium. For remineralization to work effectively, the balance must be shifted towards more calcium.
- Dentafari HAp has an ideal Ca/phosphate ratio of 16.6
- For comparison: Micro-TCP has only 0.6 (too little calcium), Nano-HAp over 150 (too much calcium, too little phosphate)
👉 This means that our HAp releases exactly the right amount of calcium and phosphate to support natural remineralization.
Porous structure - more effect
Our HAp has an open-pored, finely structured surface. This network of tiny pores creates so-called capillary forces - a physical effect that promotes the faster release of ions (minerals).
💬 In plain language: when brushing teeth, more calcium and phosphate ions are released from our HAp - faster and more specifically than with conventional nano- or micro-HAp.
It's not the percentage that counts - it's the structure
Many brands advertise with high percentages of hydroxyapatite - but this is often purely a marketing tool. Studies show: The particle structure, porosity and composition are decisive for effectiveness, not the mere content.
Thanks to its functionalization, our HAp offers significantly better remineralization performance than conventional micro- or nano-HAp - without any potential risks.
Enamel repair
Our dental care products with HAp visibly repair fine lesions in tooth enamel. Electron microscope images show:
🦷 B efore treatment: rough, damaged surface
🦷 After treatment: smooth, mineralized structure
➡️ Thanks to Hap's ability to form new, thicker enamel, teeth appear whiter, harder and smoother. The enamel is covered by the deposition of calcium and phosphate ions supported by Hap, resulting in a whiter tooth. The yellowing of the tooth is reduced by 3.5.
Remineralization of the tooth enamel
Fluoride vs. hydroxyapatite
Fluoride has long been considered the gold standard of remineralization - but it has weaknesses:
- Effectiveness depends on saliva (calcium/phosphate ratio)
- Overdosing can lead to fluorosis
- No real integration into the enamel - more of a surface effect
Hydroxyapatite, on the other hand, binds directly to the tooth structure, works from the inside out and offers a safe alternative with no known side effects - even for children and pregnant women.
Safe, natural and scientifically proven
The Dentafari formula with non-nano, functionalized hydroxyapatite stands for:
✅ Visible tooth whitening through remineralization
✅ Protection against caries and sensitivity
✅ 100% risk-free due to nanoparticles
✅ Scientifically sound and EU-compliant
🧪 Our HAp comes from Switzerland and is manufactured to the highest quality standards - for your safe, sustainable and effective dental care.
While other companies merely make claims about the quality of their hydroxyapatite products, we back up our statements with real results from independent laboratory tests.
When you brush your teeth with Dentafari hydroxyapatite tooth powder, you'll experience the new gold standard in natural dental care.
