Nanospheres to strengthen teeth:

Well, if you want to enjoy a ripe old age, you'd better have good teeth.
I wonder if this stuff can be put in chewing gum. I've heard of Recaldent™ and Dentec™ used in chewing gum for remineralization and whitening. Do those things already make use of hydroxyapatite and are these nanospheres an improvement on that?
