Whilst I can see your point of view, I think that fluoride in water is an issue that provoked knee-jerk reactions.

Here in the UK, there's areas with and without fluoridisation - the reason being that naturally the water in different areas has different fluoride concentrations with some areas having no need for adding fluoride as it's already there. The benefits were very easy to determine as (presumably) cavities were more common in those areas with low fluoride content, so it's less about experimentation and more about ensuring that more people can gain the same benefit.

There’s a left-right split on the issue in America, which leads to a lot of specious and lazy reasoning, breaking away from typical impulses to have clean unpolluted tap water, etc.
