The search for safe and effective alternatives to fluoride in dental products has led many professionals and consumers to consider nano-hydroxyapatite as a promising option. However, questions about its safety have also emerged. Is this substance really safe? What do scientific studies say? Let's unravel the truth behind this revolutionary component for dental care.

What is Nano-Hydroxyapatite and Why is it Important?

Hydroxyapatite is a mineral composed primarily of calcium and phosphorus that naturally constitutes around 97% of dental enamel and 70% of dentin. The "nano" version refers to extremely small particles that can interact more effectively with dental structure.

This component is not new at all:

  • It has been used for over 50 years in various medical applications
  • It's found in toothpastes, mouthwashes, and other oral hygiene products
  • It's also used in implant coatings, bone grafts, and even as a vehicle for medications targeting tumors

Its importance lies in the fact that it mimics the natural composition of teeth (it's biomimetic), making it a particularly compatible option for our bodies.

Scientific Studies Support its Safety

The safety of nano-hydroxyapatite has been the subject of extensive study by the European Union's Scientific Committee on Consumer Safety (SCCS), an independent body composed of experts in toxicology and other relevant disciplines.

SCCS Conclusions After 8 Years of Research

In March 2023, after a rigorous 8-year analysis, the SCCS published its final opinion on nano-hydroxyapatite, concluding that:

  • It is safe for use in toothpastes at concentrations of up to 10%
  • It is safe in mouthwashes at concentrations of up to 0.465%
  • It should be composed of rod-shaped particles (not needle-shaped)
  • At least 95.8% of the particles should have an aspect ratio less than 3

This extensive study debunks rumors about supposed bans in Europe and establishes clear parameters for its safe use.

Myths and Facts About Nano-Hydroxyapatite

Myth: It has been banned in Europe

Fact: Not only is it not banned, but it has been officially approved by the SCCS after rigorous safety studies.

Myth: All nano-hydroxyapatites are the same

Fact: The quality, shape, and size of the particles vary significantly depending on the manufacturer. The shape and origin are crucial for safety.

Myth: It causes calcifications in glands and tissues

Fact: Calcifications are more related to general imbalances in calcium metabolism and vitamin K2 deficiencies, not with quality toothpastes.

Benefits For Dental Health

Nano-hydroxyapatite offers numerous benefits that make it stand out as a dental component:

  1. Effective remineralization: Helps repair and strengthen weakened dental enamel
  2. Sensitivity reduction: Significantly relieves pain in sensitive teeth
  3. Biological compatibility: Being identical to the natural components of teeth, the body accepts it perfectly
  4. Alternative to fluoride: Offers similar benefits without the potential neurotoxic effects of fluoride
  5. Improved oral microbiome: Provides essential minerals to maintain a healthy balance of oral flora

How to Choose Quality Nano-Hydroxyapatite Products

Not all products containing nano-hydroxyapatite offer the same quality and safety. These tips will help you choose correctly:

Verify the Manufacturing Source

Experts highlight that nano-hydroxyapatite produced by Fluidinova (Portugal) meets the most rigorous safety standards established by the SCCS. Look for brands that explicitly use this source.

Read Labels Carefully

When buying products with nano-hydroxyapatite, consider:

  • The concentration of the component (ideally between 2-3% for toothpastes)
  • The absence of problematic ingredients such as SLS, triclosan, or artificial colors
  • The manufacturer's transparency about the origin of their ingredients

Consult Professionals

Before changing your oral hygiene regimen, especially if you have specific dental conditions, consult with a dentist familiar with these innovations.

Conclusion

Nano-hydroxyapatite represents a revolution in dental care, offering a safe and effective alternative to fluoride with additional benefits for oral health. Rigorous scientific studies confirm its safety when properly produced, debunking unfounded rumors circulating on the internet.
