Natural dental enamel is about 96% hydroxyapatite, a calcium phosphate mineral. Dentin is about 70%. Hydroxyapatite toothpaste repairs enamel and is non-toxic, so it is superior to fluoride.

You can already get hydroxyapatite toothpaste. Most famous is Apagard from Japan. There is also Pearlie White from Singapore. Both are available on Amazon, and Pearlie White seems to me to be a better bargain, but I have no data to support that.
