Dr Stewart Jessamine, Director – Protection, Regulation and Assurance, at the Ministry of Health discusses fluoridation.

Mild fluorosis that only dentists can see? Who is he kidding. 

No mention of money spent on teeth whitening and other expensive treatments to counter the staining of the teeth.
40% if it was true wouldn't the York review have found that convincing in 2000.
No mention of the contaminants in the acid they pour in the water with the fluoride.
If it affects the teeth it must have an affect on the bones apart from the thyroid.
It's sugar not lack of fluoride and that causes all the other problems like obesity.

Discusses fluoridation? No discussion just edited propaganda.
