In drinking water...: The World Health Organization considers 1.5 mg/l of fluoride or lower safe In drinking water. Above 1.5 mg/l dental fluorosis may occur to an objectionable degree. Concentrations between 3-6 mg/l may cause skeletal fluorosis. Above 10 mg/l can cause crippling skeletal fluorosis. Optimally fluoridated water in the USA is kept at about 0.7 mg/l and is not a problem.

4.0 mg/L: EPA has set this level of protection based on the best available science to prevent potential health problems. Fluoride is safe and effective.

Fluoride: 8mg/kg of body weight is considered to be toxic. For a 160lb male. That means about 575mg of fluoride. Review of the literature reveals no, and I repeat "no," fluoride poisoning from toothpaste, mouthwash, naturally occurring fluoride in water supplies, or water supplies fortified with fluoride.
