Hydroxyapatite toothpaste and hydroxyapatite tooth powder are conquering the German market as an alternative to fluoride dental care. But while tooth remineralization with hydroxyapatite sounds promising, there are critical questions about nano hydroxyapatite safety. We at Dentafari encourage you to take a close look at the nano hydroxyapatite risks before deciding on a product.

What is hydroxyapatite in dental care?

Hydroxyapatite tooth powder is based on the natural composition of your teeth. Hydroxyapatite (HAP) is a crystalline form of calcium phosphate - the building block that makes up 97% of your teeth. Only about 1.5% is protein (mainly collagen) and 1.5% is water.

The key difference is that not all hydroxyapatite tooth powders are the same. The remineralization of the teeth strongly depends on the type of hydroxyapatite used.

Natural vs. nano hydroxyapatite: Critical safety assessment

Many manufacturers of hydroxyapatite toothpaste use the generic term "hydroxyapatite" without explaining the key differences:

Natural hydroxyapatite

Origin: Animal bones, fish, shells, minerals such as limestone

Properties: Low solubility, safe to use when remineralizing teeth

Safety: Classified as safe by the authorities

Application: Ideal for your tooth remineralization with hydroxyapatite

Nano hydroxyapatite: The risks in detail

Origin: Laboratory production from synthetic components

Properties: Nanoparticles with unclear long-term effects

History: NASA development for demineralized astronaut teeth

Concerns: Unresolved nano hydroxyapatite safety issues

Nano hydroxyapatite risks: What does EU research say?

Current EU regulation on nano hydroxyapatite safety

After years of review, the European Union published its Revised Final Opinion on nano hydroxyapatite risks in March 2023:

"Based on the data provided, the SCCS considers hydroxyapatite (nano) to be safe for use in concentrations up to 10% in hydroxyapatite toothpaste and up to 0.465% in mouthwash."

Critical note: This nano hydroxyapatite safety assessment only applies to very specific particles:

  • Rod-shaped particles (at least 95.8% with aspect ratio less than 3)
  • Uncoated, non-surface modified nanoparticles

Unresolved nano hydroxyapatite risks

The scientific assessment reveals several problematic aspects of nano hydroxyapatite safety:

Lack of long-term data: No studies on long-term effects exist for your tooth remineralization with hydroxyapatite using nanoparticles. This is particularly worrying for your daily use of hydroxyapatite toothpaste.

Conflict of interest in research: The safety studies for nano hydroxyapatite safety were conducted by the manufacturer Fluidinova itself - a clear conflict of interest in the assessment of nano hydroxyapatite risks.

Limited test conditions: New tests on nano hydroxyapatite safety were only done in vitro (test tube) for 4 hours - a far cry from your real-world hydroxyapatite tooth powder application.

Regulatory gaps: As a consumer, you cannot check whether your hydroxyapatite tooth powder contains the safe rod-shaped or questionable needle-shaped particles.

Studies on nano hydroxyapatite risks in detail

SCCS safety assessment 2018-2021

The Scientific Committee on Consumer Safety identified several nano hydroxyapatite risks:

"The available evidence was insufficient to reach a conclusion on the safety of hydroxyapatite (nano) when used in oral cosmetic products."

Specific nano hydroxyapatite risks:

  • Potential cellular damage in kidney cells¹
  • Potential negative effects on human blood cells²
  • Unclear genotoxic potentials with your regular hydroxyapatite toothpaste use³

Further research on nano hydroxyapatite safety

A Nature study published in 2019 investigated nano hydroxyapatite safety under laboratory conditions. Although no toxicity was found in the short term, questions about the long-term safety of your daily tooth remineralization with hydroxyapatite remain unanswered.
