Harmful water fluoridation: Old news but still a 'current battle'.

An abundance of research has been conducted on this subject; I was reading more and I learned that a Doctor by the name of Phyllis Mullenix had conducted some  research in 1995. His research showed brain damage in animals exposed to moderate levels of fluoride, and ADD-like symptoms in the offspring of animals exposed to low levels. When tests bring conclusive results of the harmful effects of water flouridation, why is it continued? My daughter Zay has read more research on the topic than I have, so I will ask her to post on the topic,  so come back.
