Very nice. This is something I've been meaning to look into.
Very nice. This is something I've been meaning to look into.
TLDR of my internet research.
1) Fluoride is a neurotoxin. There are different types. 1a) Fluorosilicic acid (a.k.a hydrofluorosilicate, FSA, or HFS) is a toxic waste byproduct that they put in your water. It's not pharmaceutical grade, and often contains arsenic and heavy metals. Filter this shit out of your water. It will kill you and it does jack shit for your teeth anyway. 1b) Sodium Fluoride is generally pharmaceutical grade and what is added to toothpaste. It's not a toxic waste byproduct like they put in your water, but you should still avoid it. If you are going to put this shit in your mouth, do not swallow it and rinse extremely thoroughly. 1c) Stannous Fluoride is also used in toothpaste. It kills bacteria, but stains your teeth. I would avoid this shit too.
2) Hydroxyapatite is 70% of our bones and 90%+ of our tooth enamel. is just as effective at Fluoride in remineralizing teeth, with caveats. Again, there are different types. 2a) Micro Hydroxyapatite - these are much larger HA particles that are bigger than the microscopic holes in your teeth. Little spikes and rods stick out of the structures and can still fill the holes, though. Still, it's likely not as effective at tooth remineralization as smaller particle HA. 2b) Nano Hydroxyapatite - this generally refers to smaller HA particles, usually synthesized in a lab. There are two types: 2b1) Needle/irregularly shaped HA. You do NOT want needle shaped HA. It's been shown to damage DNA, cause inflammation, and could easily be the next asbestos. Do NOT inhale it or ingest large quantities. 2b2) Rod Shaped HA. This is what you want to use. It's small enough to fit in the microscopic holes in your teeth, but studies show it doesn't cause the same damage as needle shaped HA. You still don't want to inhale this shit in powder form. That would be very bad.
This paper lists some commercial products: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8432723/
Edit: it appears Sangi out of Japan is the most advanced. BASF and Henkel out of Germany discovered the technology, worked with Sangi on it, but BASF and Henkel abandoned the project. Sangi kept working on it for decades, made it for astronauts etc. They make the rod stuff and sell it under their Apagard brand toothpastes. The "m plus" has the least HA, "Premio" has more, and their "royal" has the most. Prices increase respectively.
