Is adding fluoride to public drinking water a good thing? For many, the answer seems obvious: Yes. Television commercials, oral hygiene products, and even traditional dentists actively endorse fluoride as a safe and effective way to prevent tooth decay. Many are surprised to learn, however, that there is no clinical evidence to support such a claim. The tide is beginning to turn, and communities across America are putting an end to water fluoridation programs that are not only a danger to residents, but also an unnecessary cost to the municipality.
