Exposure to fluoride often results in dental fluorosis. Large numbers of U.S. young people — estimated up to 80 percent in some cities — now have dental fluorosis, the first visible sign of excessive fluoride exposure. Dental fluorosis consists of damage to tooth-forming cells, leading to a defect in tooth enamel. It is also an indicator of fluoride damage to bones.
Studies reveal fluoride also attacks the immune and respiratory systems. It negatively affects blood circulation and accumulates in the bones. It attacks thyroid function. Fluoride also accelerates aging. Austrian researchers proved in the 1970s that as little as 1 ppm fluoride concentration can disrupt DNA repair enzymes by 50%. When DNA can’t repair damaged cells, advanced aging occurs. Researchers from Harvard University and the National Institutes of Health knew in the 1960s that fluoride disrupted collagen synthesis and increased aging.
