Nano-hydroxyapatite (nHA) vs. fluoride toothpaste: Without nHA regulation, it's hard to recommend it over fluoride. Fluoride toothpaste is regulated and more effective than nHA in acidic conditions. Plus, not all nHA toothpaste is created equal—many lack the necessary 10% nano-sized particles, which are crucial for effectiveness. Until nHA gets proper oversight, I’m sticking with fluoride, but I remain open-minded for those who choose to use it (and I’ll continue educating about the importance of 10% nano-size, rod-shaped particles). A lot of trust goes into companies making honest claims, and I hope to see regulatory approval one day. nHA toothpaste has great potential, but only when it meets the right concentration, particle size, and shape. Hopefully the bar will soon be raised to hold fluoride alternatives to the same high standards as fluoride. Until then, let’s keep the conversation kind and evidence-based! Additionally, nHA toothpaste is expensive—often $20-$30 per tube for those that actually contain 10%. I can’t confidently recommend something so costly without knowing for sure that it contains what it claims. If a patient refuses fluoride, I’ll suggest nHA options, but I also make sure to educate them. Without regulatory oversight, we can’t guarantee these nHA products work as advertised or that they contain the necessary 10% nano-sized particles. Hope this helps!
