Cosmetic Dentistry Center NYC, led by Dr. Pia Lieb, is evaluating nano-hydroxyapatite toothpaste claims amid growing public interest in fluoride-free oral care options. Dr. Lieb, a cosmetic dentist and clinical professor, provides an expert perspective on the benefits, risks, and suitability of nano-hydroxyapatite compared to traditional fluoride toothpaste.

Why it matters

As public discussion around fluoride toothpaste intensifies, nano-hydroxyapatite has emerged as a potential fluoride-free alternative. Cosmetic Dentistry Center NYC is addressing this trend by examining the clinical evidence and helping patients understand when nano-hydroxyapatite may be a suitable option versus the continued use of fluoride-based products.

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 these characteristics have contributed to nano-hydroxyapatite's expanding role in modern toothpaste formulations, dental professionals emphasize that it is not a one-size-fits-all replacement for fluoride, which remains a cornerstone of preventive dentistry.
