Of course it depends on whether the target demographic has adequate access to fluoride by other means, such as toothpaste. A similar case might be iodine in table salt. A lot of salt available in America is iodized on purpose. We don't do that where I live, where the usual diet is already rich in iodine. There is no single right answer, only a cost-benefit analysis for each location.
