What should you know about hydroxyapatite toothpaste?
One important consideration is the formulation. Some studies have examined nano-hydroxyapatite toothpaste at concentrations around 10%, but that doesn't mean every effective product must contain nanoparticles or have exactly that concentration.
How is hydroxyapatite toothpaste regulated?
Another consideration is knowing exactly what's in your toothpaste. Hydroxyapatite products can vary in their formulations, concentrations, and supporting research.
Unlike fluoride toothpaste, hydroxyapatite toothpaste doesn't have the same established history of regulatory review and professional recommendations for cavity prevention in the United States.
Is hydroxyapatite toothpaste approved by the ADA or FDA?
The American Dental Association has a Seal of Acceptance program that evaluates dental products for safety and effectiveness. Hydroxyapatite toothpaste shouldn't automatically be considered ADA-accepted simply because it contains hydroxyapatite.
The FDA also regulates toothpaste according to its ingredients and intended claims, but FDA oversight is different from an individual product receiving FDA approval.
Is fluoride toothpaste a better option?
Fluoride toothpaste remains a well-established option for preventing cavities and supporting enamel remineralization. It has decades of research supporting its effectiveness.
When used as directed, fluoride toothpaste is safe and effective for most people. Spit out the excess toothpaste after brushing and avoid swallowing it. For children, it's important to use an age-appropriate amount under adult supervision.
