This seems to refute your claim about Europe:

However, another study seems to indicate Germany is particularly at risk in Europe of high fluoride concentrations:

It’s not a map of places with suitable concentrations of fluoride in groundwater; it shows excess amounts. To my understanding, both Switzerland and Germany have around 1.0mg/L fluoride in much of their groundwater. This puts them firmly above municipal levels in the US, but below what your map shows.
