Yet we know that fluoride prevents 40 percent of tooth decay across one's lifetime—40 percent; just think of the big impact we could make on these conditions. I am sad to say—I am very sad to say—that this is not cutting-edge science. It not like an mRNA vaccine that we are rolling out that is a triumph of recent science developed across the last 18 months of the pandemic. There are 60 years of scientific evidence for fluoride—60 years that we have not consistently brought ourselves to act on the evidence. Many countries similar to New Zealand support water fluoridation: Australia, with whom I have said our oral health compares poorly; the United Kingdom; the United States; and Canada.
