For evidence that Fluoride is bad for you, see side-effects of Fluoride drugs like: Phen-Fen, Lipitor, Cipro, Celebrex, Fluconazole, etc... the side-effects from prolonged usage are all basically the same and match with the symptoms of Fluoride Poisoning. Dental Fluorosis is also becoming a common problem. Side-effects seem more likely in iodine deficient people.
