“Everyone on TikTok is telling you to ditch fluoride for hydroxyapatite toothpaste… but should you?”
At Elevate Dental, we love when our patients ask questions about products they’re seeing online. Nano-hydroxyapatite toothpaste is getting a lot of attention right now, and unlike many social-media wellness trends, there is legitimate science behind it. But that doesn’t necessarily mean it’s time to throw away your fluoride toothpaste.
What exactly is hydroxyapatite?
Hydroxyapatite is a calcium-phosphate mineral very similar to the mineral that naturally makes up our tooth enamel. Nano-hydroxyapatite (nHAp) simply uses extremely small particles designed to interact with microscopic irregularities in the tooth surface.
Research suggests hydroxyapatite toothpastes can help remineralize early enamel damage and may also reduce tooth sensitivity by helping block exposed dentinal tubules.
So… is it better than fluoride?
This is where social media tends to get ahead of science.
Recent systematic reviews are encouraging. A 2025 review and meta-analysis found that hydroxyapatite toothpaste may perform comparably to fluoride in preventing the progression of early cavities and promoting remineralization. However, other reviews emphasize that clinical studies are still relatively limited, with shorter follow-up periods and differences between products.
Fluoride, meanwhile, has decades of high-quality evidence behind it. It strengthens enamel, promotes remineralization and makes teeth more resistant to acid attack. Health Canada and the Canadian Dental Association continue to recommend fluoride toothpaste as an important tool for cavity prevention.
Our take at Elevate Dental
We don’t think this needs to be a fluoride versus hydroxyapatite battle.
Hydroxyapatite is an exciting ingredient with growing evidence behind it, and it may be an appropriate option for some patients. But we would be cautious about automatically replacing fluoride, particularly for children or adults with frequent cavities, dry mouth, orthodontics, exposed roots or other factors that increase cavity risk.
And remember: not every hydroxyapatite toothpaste is formulated the same way. Concentration, particle size and the rest of the formulation matter.
