Topical application of fluoride as is the case when you 'paint' it onto your actual teeth is a far more effective dental decay protection method than taking it systemically via drinking water.
Have you ever noticed that fluoridated toothpastes carry a bold "Do Not Swallow" warning? The stuff is a recognised toxin, but not when they put it in our drinking water for some reason???.
Fluoride only works topically, and you need a much higher amount like the levels in toothpaste to work.
Also the natural form most found in nature is calcium fluoride, its mechanism of action is different but actually works better, there are some toothpastes that even use it, Colgate also have products that use tin fluoride too.

From what I can gather you would need to eat a few tubes of toothpaste before you get even mild symptoms...
Only time will tell.
