I don't even consider this to be a conspiracy theory, there have been numerous studies that have proven fluoride to diminish IQ in children. Fluoride is also associated with several health problems and is being added to 60% of drinking water in America, mostly against the will of the citizens. There have been absolutely no studies that prove fluoride to be beneficial to the healthiness of teeth, in fact; it has been revealed to have quite the opposite effect. So my question is; why do you think its presence has become so prevalent in the United States water supply?
