"Every $1 invested in fluoridation saves approximately $38 in dental treatment costs, according to the C.D.C. The cost of a single filling averages $140, and that’s only the beginning. Through the years, a filled tooth is likely to require further repairs and maybe even extraction and replacement with a bridge or implant costing thousands of dollars.
None of this, however, has quelled the controversy over the safety of fluoridation, which dates back to the first studies in the 1940s. In addition to being labeled a Communist plot and an unconstitutional form of mass medication, fluoridation has been accused of causing a host of medical horrors: heart disease, cancer, Down syndrome, AIDS, allergies, Alzheimer’s disease, mental retardation, osteoporosis and fractures, among others.
None of these supposed risks has ever been established in scientifically valid studies. The only proven risk, a condition called fluorosis, which results in white and sometimes brownish markings on the teeth from too much fluoride, rarely results from a normal intake of fluoridated water."
