New research indicates fluoride may pose a risk

The U.S. National Institutes of Health recently announced funding to York University (Toronto) researcher Christine Till to further investigate the effects of fluoride exposure to the brain and nervous system. In 2014, Till along with Ashley Malin, published a study linking higher rates of ADHD to fluoridated areas of the U.S.

The promoters of fluoridation assure us that fluoridation is "safe and effective" at present exposure levels, but the Canadian Dental Association noted in 2012 that dental fluorosis, a condition resulting from high cumulative fluoride ingestion from all sources during childhood, is still increasing in Canada. That acknowledgement, along with the presence of dental fluorosis in many people raised in non-fluoridated communities, should be sufficient evidence to suspend the fluoridation of tap water in Canada until we have more information about the effects to other parts of the body than the teeth.

To those who continue to promote fluoridation, I ask: "What primary research can you cite which would allow us to ignore the current 300 animal and human studies, including 50 related to IQ, that link fluoride to negative neurological effects? I am not looking for endorsements or reviews- those are subject to bias.

I would like to see valid research that looked for harm but didn't find any. In 1999, the U.S. CDC acknowledged that "fluoride prevents dental caries predominately after eruption of the tooth into the mouth, and its actions primarily are topical for both adults and children." Why are we taking any chance in exposing the whole body to fluoridated water, without knowing how much water each person drinks, or how much fluoride they are already getting from other sources, especially when topical applications like toothpastes and rinses are simple and cheap for those who want them?
