there is no escape from fluoride. its in our air, our water, our food and everything we touch. all of those cardboard containers people get pizza in and microwavable packages? fluoride. my wife bought an eagle brand fudge mix that came with its own paper box to pour the fudge in(dont blame me, i cant control her) and that paper box was coated.
i hate fluoride in all its forms. we get more than we need just by breathing outdoors. avoid all the rest if possible. good luck with that.
