I recently started using a nano-hydroxyapatite based toothpaste. It can't restore enamel but does better at remineralization than fluoride, hopefully it will be a good intermediate for me until something regenerative is available.
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.

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)

To everyone reading this you should still use flouride! Flouride and nanohydroxyapetite together both strengthen the outside layer of your teeth while strengthening the inside of them. Either alone is good, both together are great.
Oh! To clarify. I use fluoride in the morning and hydroxyapatite at night.
Hydroxyapatite based paste is incredible, and has astonished a few of my incredulous friends dealing with dental problems.
It always seemed very interesting in a cynical way that Sensodyne Repair and Protect has a European version with hydroxyapatite but doesn't offer it in the US. The only reputable US brand I'm aware of is Dr Collins Biomin, which is excellent but weak on the hydroxyapatite.
I'll be abused for it here, but I'm intractably convinced the ADA and generally despicable US health industry prefer to avoid it due to its efficacy and how much revenue would be lost if it were more common. Say what you will against this, and I'll remain convinced.
AFAIK the European version of Sensadyne Repair and Protrct uses Novamin, not Hydroxyapatite. From what I can tell, they are similar but separate chemicals.
While not sold directly in the US, Sensadyne with Novamin is available from Amazon (usually from India).
Thanks for clarifying that. I'm confused that my head still insists there was hydroxyapatite involved, but I believe you're correct. My information is over a decade old though.

I appreciate the info, but it honestly seems this person is blabbering, barely presenting even anecdotal evidence and literally just saying it's bad because she thinks maybe it is, because, hey look at my friend over here who nods. Definitely makes me wonder if the "Dr" in her handle is more than text.
That said, I'm not surprised people argue against it. But my teeth haven't "crumbled" after more than a decade of regular apatite use, and that's under various impacts and hard use. If there's any validity to her concerns about it, she should actually discuss them, instead of talking about charcoal and her friend.
I pick up a couple tubes of that Sensodyne every time I’m in Europe.
What product(s) do you recommend? I'm in the US.
Either Biomin, or my first choice, Apagard (from Japan).
Biomin is cleaner, but weaker.
I generally choose Apagard though. If you do too, the Premio is a good version with a substantial hydroxyapatite content.
Try to buy from a reputable seller if Apagard. I'd not worry about Biomin much.
Edit: also note that these are rinseless pastes, intended to remain on the teeth for as long as they linger. This is where Biomin has an advantage, being cleaner. Spitting is fine, but rinsing will reduce efficacy.
Edit II: Some will wail in disagreement. I think a waterjet can literally add years to the average lifespan while helping with oral health. Maybe consider one, with simple design and minimal features.
Smart mouth has a flouride + hydroxyapetite. I’ve been using it for a few months now and all my tooth pain is completely gone. I’ve been dealing with issues for years and have a wonderful dentist but really had to get myself in shape and brush 2x and really floss correctly. Anyway, that toothpaste also helped compared to only stannous fluoride paste.
Dave's is available in the U.S. and has NHAP, flouride, and the anti-sensitivity stuff from Sensodyne.
