Nature (9 April 2022), briefly on the use of finely-powdered calcium phosphate on teeth. (Apatite is a hydrated version). Since the outsides of teeth are separated from the bloodstream, they can be experimented with, for example by eroding the surface, then experimenting to see if it can be regrown back. There seem to be at least two toothpastes available; one is Italian (Biorepair), which I got the impression was original and best; another Wolff brand (Bioniq) which I got the impression is a Jewish copy.
Some of these are on Amazon, which I've learned to dislike for various reasons. So the market is the usual Jewish-dominated chaos. But products of this type look set to take over, with fluoride toothpastes sold off cheaply to underclasses, 'COVID vaccine' style.
Sodium fluorophosphate is presented sometimes as an alternative to sodium fluoride. It may refer to a compound with a modified phosphate ion, not PO
4--- but the same thing with one oxygen atom replaced by a fluorine atom, slightly smaller. This sounds safer and insoluble, but the sheets on it say it's toxic.

Influence of Dietary Chloride on Fluoride Bioavailability in the Rat by Florian L Cerklewski, James W. Ridlington and Nathan D. Bills in the
Journal of Nutrition (
J. Nutr. 116: 618-624, 1986):–
A factorial experiment was conducted with weanling rats fed a purified diet to determine the influence of dietary chloride (0.02, 0.10, and 0.5%) as sodium chloride on fluoride non-availability (2 or 10ppm as sodium fluoride). After 8 wk, rats fed the lowest chloride-containing diets had significant reductions of plasma chloride, urinary chloride excretion and growth rate compared to other chloride groups. Depressed growth occurred in rats fed chloride-deficient diets despite the fact that food intake was similar for all treatments.
Fluoride retention was greatest in chloride-deficient rats, which was reflected in enhanced skeletal uptake of fluoride. Fluoride absorption was not inhibited by high chloride intake. We therefore conclude that emphasis on the effect of chloride on fluoride bioavailability should be directed towards an enhancement of fluoride retention by low salt (sodium chloride) diets rather than in terms of a possible negative effect of a high salt diet on fluoride absorption.
