In the UK at least some areas have fluoridated water, despite almost all toothpaste being fluoridated. I suppose it most benefits the minority of people who do not brush their teeth. That benefit has to be balanced[1] against some evidence of risk.

IMO the right fix is better dental hygiene, and a better (less sugary) diet. These are in turn are in part symptomatic of other problems (poverty, long working hours with regards to lack of supervision of children).
