It seems to me the two are effectively the same unless you have significantly misshaped teeth (remineralizing vs regenerating). I also use hydroxyapatite, just to reduce my fluoride exposure, although I believe fluoride is supposed to be a more potent remineralizer (and fluorapatite is allegedly stronger than natural hydroxyapatite). But the upside is that I don't mind swishing hydroxyapatite around in my mouth for 10 minutes, twice a day, so whenever I go to the dentist, I'm the healthiest mouth of the day (not the case pre-hydroxyapatite tooth paste/powder).

NHAP particles are smaller than fluoride particles, so they're able to penetrate farther into the porous surface of the teeth; flouride basically can only coat the surface. There is some research indicating that NHAP is more effective than flouride at remineralizing (e.g. https://pmc.ncbi.nlm.nih.gov/articles/PMC4252862/) but that flouride is more protective than NHAP because NHAP isn't protective at all. (The flouride creates a temporary sacrificial enamel-like shell layer that closes off pores in the surface of the teeth in addition to buffering acids; the NHAP will just create new enamel.)

My dentist says that NHAP is great if you have lots of cavities or drink lots of acidic drinks like soda, but once your enamel is repaired too much of NHAP can actually cause weird growths.

Dave's toothpaste has both NHAP and flouride (and the sensitivity agent used in Sensyodyne) if you're looking for the best of all worlds in the U.S.

>Dave's toothpaste has both NHAP and flouride

And has an RDA of 101. Why on earth would a toothpaste meant for sensitivity have this high of an RDA? (Non-whitening sensodyne is around the 40s)
