Recently, I think, as my colleague Dr Anae Neru Leavasa was saying, the Office of the Prime Minister's Chief Science Advisor has reported on an updated review regarding fluoride in drinking water. Unsurprisingly, that review continued to highlight that New Zealand has relatively low levels of fluoride in our drinking water—we have naturally low levels of fluoride in our drinking water; our drinking water is not as perfect as some people might like to think of it as being—and that those insufficient levels that occur naturally in our drinking water don't, therefore, contribute to better dental health outcomes, and that adding fluoride to water continues to have a positive impact by reducing the incidence of dental cavities, which is particularly important in reducing socio-economic health inequalities.
