Fluoride is an anticholinergic agent. According to Wiki "Acute anticholinergic syndrome is completely reversible and subsides once all of the toxin has been excreted... The current recommended treatment is symptomatic and supportive management." Isn't that what we get, a trip to the doctors is nothing more than symptomatic management.

A dentist's placement of fluoride in teeth as fillings etc., provides a constant flow, 24 hours a day. Fluoride also synergizes poisons from previous fillings i.e. mercury stored in tissue. So, I find myself in a position where my fillings are 12 years old and perhaps a little light on fluoride. I'm not letting them replace them.
