You are much better off using nanohydroxyapatite for that, though; you can easily import such toothpastes from Japan via Amazon.

See also the bioactive glass compounds BioMin (fluoro calcium phosphosilicate) and NovaMin (calcium sodium phosphosilicate), which come in toothpastes that also include fluoride to cover all the bases.

BioMin F is as effective as nanohydroxyapatite, and is less expensive than the Apagard nanohydroxyapatite toothpaste. (BioMin F is not yet available in the U.S. and needs to be imported.)

Interesting. Hadn’t heard it it before, but at least according to this and it’s linked paper it’s roughly equivalent. What makes you say that you’re better off?

I use this stuff and I stopped getting cavities. Just one example obviously, but it was night and day better I think. It's a little pricey is all.

It's great for tooth sensitivity as well.

there is boka an American company. there are others as well, no reason to import from japan.

Source?

Not really a source, but this Dental Hygienist talks a bit about hydroxyapatite. Sounds like it could be of at least equal effectiveness. Though further studies are needed. https://youtu.be/kQAPEZaqwfY?t=63

Not OP but I have a family member who’s a specialized dentist who’s well regarded in the field and constantly harps on this kind of toothpaste over fluoride. I think fluoride is basically cheap and that’s all
