Fluoride is known for its many uses especially in dentistry and water treatment. However, excessive fluoride exposure may prove detrimental to the body’s overall health, and may even lead to various adverse medical conditions. In fact, The Lancet has officially classified fluoride as a neurotoxin. This puts the element in the same category as other neurotoxins including arsenic, lead, and mercury.
Fluoride exposure may come from various sources including public water fluoridation, fluoridated toothpaste and mouth rinse, untested bottled waters, and certain foods. Vitamins, dietary supplements, and insecticides are also known sources of fluoride exposure. Natural water also appeared to be a common source of excessive fluoride exposure. According to the World Health Organization (WHO), millions of people worldwide are exposed to this neurotoxin through drinking water that is taken from natural geological sources.
