If you read the evidence that went before the Health Committee in the last Parliament, as I have done, and the evidence in the departmental disclosure statement that the Government has put on the table now for four or five years, it is very clear that the benefits of fluoridation are manifest and it makes a difference. That is why when you compare the water supplies in New Zealand that are fluoridated in comparison to the water supplies that are unfluoridated, you can see the difference that fluoridation makes.
