Fluoride is an element that occurs naturally in the environment, however it is also produced synthetically for use in toothpaste and mouthwashes. Due to a long history of corporate incentives and cherry-picked studies that dates back to the 50s, fluoride was approved to become an additive in American drinking  water “to promote strong teeth.” Approximately 300 studies, as evidenced below, demonstrate fluoride is a neurotoxin, linking fluoride exposures to reduced intelligence. Studies have also found associations with arthritis, cancer, cardiovascular disease, diabetes, endocrine disruption, gastrointestinal effects, and infertility. More recent studies have found a toxic synergy between fluoride and aluminum. From 2000 to 2004, 125 communities in 36 states adopted fluoridation of their municipal water supplies, however other cities, such as College Station, Texas and Watsonville, California, have overturned fluoridation mandates. Only about 2% of people receive artificially fluoridated water in Europe, with countries like the Netherlands and Italy rejecting the additive. Fluoridation is banned in China, due to cases of increased dental fluorosis from naturally occurring fluoride in their water supply.
