During the last several decades, many studies have examined a possible link between fluoridated water and cancer. In the 1990s, the National Cancer Institute, the Public Health Service, the National Research Council, and the Centers for Disease Control and Prevention reviewed dozens of these studies. They found no evidence that fluoride causes cancer in humans.
All water contains fluoride.
In the 1940s, scientists discovered that the higher the level of natural fluoride in the community water supply, the fewer the dental cavities among the residents. Today, more than half of all Americans live in areas where fluoride is added to the water supply to bring it up to the level considered best for dental health. All Rights Reserved.
