William Jarvis liked to put on water fluoridation debates for his students at Loma Linda University's School of Dentistry. He would ask them to vote twice -- before the debate and after.Debates expose these facts:
``We always had people favorable toward fluoridation before the debate and less favorable after,'' said Jarvis, who retired two years ago as professor of public health and preventive medicine.
- Scientists no longer believe that they have evidence that fluorization has a systemic benefit. (Ie, the only known benefit is topical, meaning from direct contact between fluoride and teeth, and not from consumption of fluoride.)
- Fluoridation does not benefit those who brush their teeth with fluoride toothpaste.
- At least 10% of the population shows adverse medical effects of consuming too much fluoride.
Update: A measure to stop fluoridation passed by 32 votes. The city says that it is going to fluoridate anyway.
