Fluor is an electron stealer. Enough for me not to touch it with a ten foot pole. Besides, tooth regrowing/regeneration will be available in the next few years.
> Fluoride, as an ion (F-), is not reactive in the same way that elemental fluorine (F2) is. Fluoride ions are stable and typically do not readily gain or lose electrons, while elemental fluorine is highly reactive due to its strong electronegativity and tendency to attract electrons from other elements.
