Generally Europe doesn't fluoridate its water, true, but the practical effect is a bit more nuanced. For example, Germany has mostly moved its fluoridation program from water to salt: http://www.ncbi.nlm.nih.gov/pubmed/16156167
In Denmark the water isn't fluoridated, but its natural levels of fluoride are only slightly lower than the levels that U.S. cities add (for example in the Copenhagen water supply, fluoride is around 0.6 mg/L). So it's a bit pedantic to claim that it isn't fluoridated. It's true that the utility company is not adding more fluoride to the water, but the end result is still that the pipes are delivering tap water with fluoride in it.
