Water fluoridation is the practice of adding industrial-grade fluoride chemicals to water for the purpose of preventing tooth decay. One of the little known facts about this practice is that the United States, which fluoridates over 70% of its water supplies, has more people drinking fluoridated water than the rest of the world combined. Most developed nations, including all of Japan and 97% of western Europe, do not fluoridate their water.
In the United States, the Oral Health Division of the Centers Disease Control (CDC) hails fluoridation as one of the “top ten public health achievements of the 20th century.” However, comprehensive data from the World Health Organization reveals that there is no discernible difference in tooth decay between the minority of western nations that fluoridate water, and the majority that do not. In fact, the tooth decay rates in many non-fluoridated countries are now lower than the tooth decay rates in fluoridated ones.
As is becoming increasingly clear, fluoridating water supplies is an outdated, unnecessary, and dangerous relic from a 1950s public health culture that viewed mass distribution of chemicals much differently than scientists do today. The few nations that still fluoridate their water should end the practice.
