Cosmetic Dentistry Center NYC, led by Dr. Pia Lieb, a cosmetic dentist and clinical assistant professor emerita at NYU College of Dentistry, is evaluating nano-hydroxyapatite toothpaste claims amid growing public discussion around fluoride-free oral care options. Dr. Lieb provides an expert perspective on the benefits, risks, and suitability of nano-hydroxyapatite as a potential alternative to traditional fluoride toothpaste.

Why it matters

The rising popularity of nano-hydroxyapatite reflects growing interest in personalized dental care, as patients seek alternatives to universal fluoride-based solutions. Cosmetic Dentistry Center NYC is at the forefront of this shift, ensuring patients receive recommendations grounded in research, safety, and individualized dental needs.

The details

Nano-hydroxyapatite is a synthetic form of the mineral naturally present in tooth enamel, designed to mirror the tooth's own structure. Emerging research suggests it may help promote enamel remineralization, ease tooth sensitivity, and form a protective barrier along the tooth surface. While nano-hydroxyapatite is an interesting and promising technology, dentists caution against abandoning fluoride without professional guidance, as fluoride remains a cornerstone of preventive dentistry, strengthening enamel and reducing the risk of tooth decay.

  • The growing public discussion around fluoride toothpaste has been amplified by recent national reporting.

What they’re saying

“Patients are asking more informed questions than ever before. Nano-hydroxyapatite is an interesting and promising technology, but it is not a one-size-fits-all replacement for fluoride. Each patient's dental health, risk factors, and goals must be taken into account before making that decision.”
