We've heard in 2014 there was a review, a comprehensive review, by the Royal Society Te Apārangi looking at the health effects of water fluoridation. I know many will say, "Why are you going on about the science behind this?" Because I know that many take their research from "Dr Google", you know, so it is our job, for those who are watching or will watch this in replay, to provide that scientific evidence, and they can reference it and they can go see for themselves. I always say to my patients: make sure that we're getting the information from reputable sources and not just going off and doing a "Dr Google" search. That review in 2014 found that there were no adverse effects of fluoride of any significance arising from those levels that we use in Aotearoa. There is new research on fluoridation, comprehensive reviews, that have been published subsequently. The 2014 review still remains appropriate, and that is up-to-date research.
