How does this compare with nano-hydroxyapatite, which is the current rage in toothpaste innovation and remineralization?

nHA is prohibitively expensive to produce and the most effective process that produces the smallest particles is patent-protected by Sangi, and therefore many nHA toothpaste brands only contain a fraction of the concentration used to produce the effective results reported in academic studies (1-2% instead of 10%).

If keratin toothpastes can be produced more economically they could be a better option for mass adoption. For anyone who wants to try nHA toothpaste for remineralization, I can only recommend Sangi Apagard Royal toothpaste ($$$) but it does work quite well when used as directed.

    bah it's like $15-20 a tube that will last a couple months. That's nothing to most people on hackernews

    First time I've heard about apagard royal. In India it costs ₹5145 or $60 appprox.

    Thats... substantially more expensive than regular toothpaste. Which costs ₹100-₹200 or $2-3.

      Regular toothpaste is just detergent (SLS) with sand (silica) and smelting waste (fluoride) added. Not surprised
