Several people raised the notion that fluoride is a poison. Sodium fluoride is, indeed, poisonous, in the same way that table salt is poisonous. In fact, sodium fluoride and sodium chloride (salt) are very similar substances, chemically speaking. In large quantities, they represent a danger to the body. Salt does not kill us because we are smart enough not to ingest large quantities, and sodium fluoride in drinking water will not kill us for exactly the same resaon. It is added in very small quantities.
One writer referred to getting his information from a naturopath. As individuals, we are all entitled to get our medical care from whatever provider makes us feel comfortable. However, we should not be relying on naturopathy to set public health policy any more than we should be relying on astrology to set our space exploration policy, or Rush Limbaugh to set our national political agenda.
Too many people get their complete science information from newsletters and web sites written by people with about as much scientific background and credibility as President Bush. These newsletters include lots of ranting and raving designed to stir up anger and outrage, but ranting and raving does not make science. The scientific process is a gradual one, in which hypotheses and experimentation leads us from a general idea to a specific understanding.
People are entitled to righteous indignation and outrage. The right to express outrage is guaranteed in the constitution. But unless that outrage is actually based on facts or evidence with a well-established basis, it should have no effect on public health policy.
Flouridated water has proven benefits for dental health. It reduces tooth decay measurably and provably. Objecting to its use because of hysteria, pseudo-science, and unsubstantiated rumors is neither productive nor good public policy.
