fluoride: a dentist observed that he had a group of patients that while having occasionally brown spots on their teeth, simply never got cavities. Further exploration recognized they had unusual levels of fluoride in their well water. Further experiments were performed to determine if the level of fluoride could be modulated to eliminate the side effect (browning, a fluorosis of sorts) while maintaining the benefits (prevention of tooth decay). The results were conclusive, fluoridation is the result. It is a simply case of an observant health care provider and solid follow up.
