Water fluoridation is safe

Thanks to ax123man for defining water fluoridation. Rebuttals "We are also exposed to fluoride at various levels in toothpaste and with topical treatments at the dentist. Since 1992 the ADA has required toothpaste manufacturers to include 'Use only a pea-sized amount (of toothpaste) for children under six' on labels." Well, this does not prove that it is unsafe as although water fluoridation has been praised as one of the top medical achievements of the 20th century, fluoride-containing toothpaste can be acutely toxic if swallowed in large amounts. [1] Without giving the dose ingested and how many fluoride are in there, you cannot just say that it is toxic. "The EPA does not know for sure what levels of fluoride we consume." That is because it isn't its job. The EPA regulates tap water and as the name says, protects the environment. "Recent medical studies refute the EPA claims." You cannot say that recent studies refute it if you do not say: -Which medical study says it. e.g., I can say that I heard that __ happened to __ on the internet, but it has no validity as the website is not given. -How much fluoride (dosage) is used. e.g., A study may show that large amounts causes __, but the dose is nowhere near the dose used in water. "Given the emphasis placed on aesthetics in relation to tooth care these days, I believe many people would consider visible signs of dental fluorosis as "unsafe"." Dental fluorosis is the developmental disturbance of dental enamel caused by excessive exposure to HIGH concentrations of fluoride during tooth development.[2] This is possibly higher than the recommended dose. Arguments Cancer Science findings show no or uncertain (equivocal) evidence on the correlation between fluoride and cancer. Taken together, the two animal studies fail to establish an association between fluoride and cancer. "Under the conditions of these 2-year dosed water studies, there was equivocal evidence of carcinogenic activity of sodium fluoride in male F344/N rats, based on the occurrence of a small number of osteosarcomas in dosed animals. There was no evidence of carcinogenic activity in female F344/N rats receiving sodium fluoride at concentrations of 25, 100, or 175 ppm (0, 11, 45, 79 ppm fluoride) in drinking water for 2 years. There was no evidence of carcinogenic activity of sodium fluoride in male or female mice receiving sodium fluoride at concentrations of 25, 100, or 175 ppm in drinking water for 2 years." ---The Ad Hoc Subcommittee on Fluoride [5] "The other carcinogenicity study was sponsored by the Procter and Gamble Company using Cr:CD (Sprague-Dawley) rats and Crl:CD-1 (ICR) mice both treated with 0, 4, 10, or 25 milligrams/kilogram/day sodium fluoride added to a low fluoride-basal diet. A second control group received powdered rodent chow. There was no evidence of malignant tumors associated with sodium fluoride in mice and rats of either sex in the Procter and Gamble study. While there were two osteosarcomas in the low dose female rats, one osteosarcoma in a high dose male rat, and one fibroblastic sarcoma in a mid-dose male rat, these findings in treated animals were not statistically different from controls."
