It is strange that you make such  false claims. Everyone can go read the research studies themselves that show an increase in CANCER caused by fluoride. 

Only stupid cave dwellers claim that the fluoride chemical added to drinking water,  hydrofluorosilicic acid, is not an industrial toxic waste product. That is where the big profits come from at the expense of community citizens. It is not only ineffective for teeth  but accumulates in bones and brains, lowering IQ in children and causing ADHD. That is why the world (only 5%) and specifically Europe (only 3%) has rejected fluoridation.
