They also noted that, in 2019, there were 7,000 hospital admissions for children coming in to get dental treatment done. They also reported the same large inequalities that we were seeing back when I was doing it—much higher rates for Māori and Pacific children and those living in more deprived areas. They also cited the 2018/19 New Zealand Health Survey and what they found was that less than 60 percent of children brush their teeth at least twice daily with a standard fluoride toothpaste. So I think if we're relying on children's behaviour to top up fluoride, it just shows some of the challenges that that involves.
