(The organic calcium-fluoro-phosphate)
Sodium fluoride is entirely different from organic calcium-fluorine-phosphate needed by our bodies and teeth. The organic calcium fluoride is an edible organic salt, is insoluble in water and assailable by the human body, whereas the non-organic Sodium Fluoride used in fluoridating water is toxic and fully water soluble.
