Deep dives
The Historical Context of Water Fluoridation
The origins of water fluoridation trace back to the early 1900s when a dentist named Frederick McKay observed a peculiar dental phenomenon in Colorado Springs. Residents had brown stains on their teeth but reported significantly fewer cavities than in other regions. Investigations revealed that regions with brown-stained teeth had higher natural fluoride levels in their water. This discovery sparked a public health initiative to introduce controlled fluoride levels into municipal water supplies across the United States.
