Comment: We have a "land of fluoridation" locally  --  it's Forks, WA, which has fluoridated its water for decades.  We also have an Eden, a "land" where fluoride has never been added to the water  --  Sequim.  Children's dental health is much worse in fluoridated Forks than in  unfluoridated Sequim.  

Clearly, things work very similarly in Europe, where the same governments that provide everyone's health and dental care have decided to stop fluoridating their water.  Silly governments  --  they say they've made that decision because the supposed benefits to oral health are unproven, and the detriments to systemic health are real.
