Regarding the addition of fluoride to our water supply, the advice from the Ministry of Health states:
“Over 60 years of international and New Zealand research tells us that water fluoridation is safe and effective ... at the levels used in Aotearoa/New Zealand.
“It is absolutely clear that at doses used in New Zealand ... there is no risk from fluoride in the water ... there are no reported cases of disfiguring dental fluorosis associated with the fluoridating of water supplies in New Zealand.
“We conclude that the scientific issues raised by those opposed to fluoridation are not supported by the evidence.”
