The debate over water fluoridation goes back to the 1940s when communities began fluoridating water to prevent tooth decay. According to the Centers for Disease Control and Prevention (CDC), the fluoridation of water was one of the greatest public health achievements of the 20th century.
Fluoride is a natural mineral found in soil and water in varying amounts. It is believed to combat tooth decay and cavities by making enamel more resistant to bacteria. However, previous studies have shown that exposure to high levels of fluoride inhibits the production of iodine, which is crucial for a healthy thyroid.
It is for this reason that adding extra fluoride to water for the purpose of medical treatment has become a controversial topic of heated debate. For decades, fluoride has been forced upon us by governments who have spiked our drinking water to improve oral health. However, there is a growing body of evidence suggesting that fluoride-spiked water may do more harm than good.
