Probably because of diet or availability of dental care. But if only 4/44 countries in Europe fluoridate, then fluoridating countries are over represented in that example’s 7 ( ie if fluoride didn’t help we would expect it to be 10/11).
Why did you pick top 7 by the way? Is it 6/8? 6/9? 6/10? It’s an extremely weird threshold and makes me think you’re cherry picking data to suit your narrative.
