Steven Slott 197, You LIE.  I have access to 154 peer reviewed scientific studies that confirm the toxicity and harm from "optimally fluoridated water" at 0.7 - 1.2mg/L (1 ppm in average). 

Sources: Journal of Molecular Medicine, Environmental Toxicology and Pharmacology, Biochemical Journal, Biochimica et Biophysica Acta, Journal of Clinical Endocrinology and Metabolism, Matrix Biology, International Journal of Hygiene and Environmental Health, Toxicology and Applied Pharmacology, Journal of Applied Toxicology, Toxicological Sciences, Cell Death and Differentiation, Journal of Comparative Physiology B, Toxicology in Vitro, Archives of Toxicology, The Journal of Biological Chemistry, Cancer Chemotherapy and Pharmacology, International Journal of Molecular Sciences. 
There's quite a bit more and I can continue, but, I think you should get my point by now that there is indeed  a SUBSTANTIAL number of "peer reviewed" studies on the subject of Fluoride Toxicity since 1942.
