So it is a big problem in the community. Tooth decay is the leading cause of preventable hospital admission in children in this country. In the medical practice that I worked in, we had a lot of Māori and Pasifika - population patients, and they are some of the highest affected as well, with tooth decay. Their oral health is a lot worse than other people in New Zealand. Now, in 2019, more than 40 percent of all five-year-olds and more than 60 percent of Māori and Pasifika five-year-olds already had some sort of tooth decay. The figures are similar for other adults. And, as I said, I've had to deal with quite a few of these in my practice. But many of the countries we routinely compare ourselves to in the OECD—Australia, UK, USA, and Canada—support water fluoridation. We won't actually be leading this; we would actually, if anything, be just following other people that we align with, amongst other things.
