Does water fluoridation have negative side effects

(Note by Dr. Andrew Saul: Fluoridation of water owes its continued existence more to politics than to science. If safety and effectiveness are truly considered, fluoride would be questionable even as a prescription drug. But to freely add it to public water supplies, often without any public vote whatsoever, is far beyond questionable. Mr. Meiers' discussion of the dangers of fluoride is important reading.)
