The debate regarding Fluoride continues to rage, is it good for your teeth or, the teeth of our children. There does not appear to be a survey available, without bias, that goes one way or the other.We could say that Fluoridisation of the water supply is an expensive exercise, because it is only intended for drinking, but is actually being used for washing clothes, cars, used in showers and baths, also for watering the gardens and lawns.
Obviously a more cost effective option, would be to supply.
