Welcome to the State of California 


Is dental fluorosis or mottling of the teeth the first visible sign of fluoride poisoning in children?  No.

Dental fluorosis is NOT a sign of poisoning. It is a condition where the dental hard tissues (enamel) are more porous than is found in normal enamel. Drinking fluoridated water at the optimal range of 0.7-1.2 ppm of fluoride will not cause noticeable dental fluorosis or any functional or cosmetic risk to teeth (Thylstrup and Fejerskov, 1978). Mild cases of fluorosis may occur in 10-15 percent of children who drink fluoridated water from birth: however, this degree of fluorosis is detected only by a specially trained and experienced dentist and is not a generalized health effect (National Research Council, 1993).
