Enamelon Toothpaste from the 1990s:

"proven to strengthen tooth enamel" I remember researching the stock and deciding not to buy.
Patents from the 1990s https://patents.justia.com/assignee/enamelon-inc
It seems the company is still around https://www.enamelon.com
What about "Sensodyne Pronamel"? There is usually someone in the comments raving about its effects.
I think usually they rave about Novamin, which, at least in Canada, isn’t in the Pronamel line IIRC but in other Sensodyne branded toothpastes.
_EDIT: “repair and protect”_
This was a good comment thread on which brands or markets had what with regard to hydroxyapatite:

I can be that someone this time. The ”repair and protect” version has helped my low-level toothache.
I've actually been occasionally using Enamelon because it was recommended by my dentist for sensitivity and I think it actually works.
I'm going to try Boka as recommended above though, it seems like a more updated and modern solution.
Did you tried :D ?
