The science has confirmed this repeatedly for decades, but the fluoride-lobby just won't stop defending it's position. Until it comes a time where awareness of the negative impact of fluoride is so high there is no more hiding the truth. Corporate funded science sways public health policy until the time comes that people clearly see the light. Remember Tobacco Science 'safe and effective' - my Grandad was recommended to smoke by his Doctor who said it was good for his nerves. It was was good at developing a grapefruit sized tumour. Oh look even the Dentists recommended you to smoke (his sponsored brand).
