I know it's not directly a general science to be fit in here, but I was researching stuff to keep your teeth healthy and shiny and came across two technologies that are by far the most effective.
Stannous fluoride is far more effective than sodium fluoride or sodium monofluorophosphate, but has been replaced by both because they are simply a lot cheaper and they still sort of do their job. But the initial toothpastes used the superior stannous fluoride.

Second technology used lately is hydroxylapatite. This substance is actually a building element of every tooth. It has been used before, but the problem is, if the hydroxylapatite particles are too big, they don't adhere well enough to the tooth surface and they also cover the hydroxylapatite rods on the surface of the tooth, making it harder to further adhere building material. New technologies brought nano-hydroxylapatite which finally brings hydroxylapatite in small enough particles to behave the same way natural hydroxylapatite is introduced to the tooth enamel.

Now, the thing here is, has anyone, anywhere seen a toothpaste that combines both, stannous fluoride (SnF2) and nano-hydroxylapatite (nHA) inside one package?
So far after searching, I've only found versions that include one or another or at least nAH with NaF or in case of Megasonex, only nAH without any kind of fluoride. I'm assuming that if you combine SnF2+nAH it would be a bit more expensive, but should be a superior combination. Or is there a reason why nAH doesn't need fluoride to bond even faster to the enamel?
