Youtube scientist C0nc0rdance addresses the pseudo-science against flouridation of drinking water.

3. What is wrong with plain old water?

Why must it be fluoridated? If people want sparkling teeth, they can go get fluoride treatments at the dentist.

Fluorine is a fairly toxic ion, it has a high affinity for calcium, as expressed in the phenomenal stability of the CaF2 molecule. Interestingly, the ion channels responsible for nerve signalling rely on the Ca(2+) ion for the work it does.

The range of concentrations in which F(-) ion is safe for consumption is quite small, and a reflection of this can be found on the warning found on the containers of fluoridated toothpaste. An issue that no one should ignore is a problem stemming from careless fluoridation, as the possibility of getting an aliquot of *highly* fluoridated water from the municipal water supply is very high. Cases of fluorosis are not unknown (common, actually), and most stem from the poor quality control happening at city level.

Having worked in the pharmaceutical industry, I am an actual chemist, I can say that I am intimately aware of the issues surrounding mixing efficiencies. It is very, very difficult to prove to the FDA that your drug is evenly dispersed in your mixing container, and engineers spend entire careers on this problem alone.

Now, without delving into conspiracy-land, is your dismissiveness towards legitimate concerns actually that informed?
