Dear EarthTalk: So, what’s the story: Is it good that we have fluoride in our tap water or not? I’ve heard so many conflicting opinions over the years. -- Benjamin P., Mission, KS
The debate over whether we should add fluoride to public drinking water has raged since the 1940s when American cities first initiated the practice as a way to fight the scourge of tooth decay. The benefits of more research and hindsight in recent years have led many policymakers to reconsider the merits of so-called artificial fluoridation. The U.S. Centers for Disease Control (CDC) reports that today over 60 percent of Americans get fluoridated drinking water from their taps whether they want it or not.
