Wiki isn't always all that accurate, but perhaps you have cherry-picked the info.

I well remember discussing fluoridation, with my parents, and what I had heard about Birchers, as a child. I know that it was long before Dec. 9, 1958, because not only was I at boarding school at that date, but we no longer was living at the place I well remember talking about the fluoridation hysteria.
