We're picking up this debate after some time, so it is worth returning to some of the facts on fluoridation. In doing so, let's start with the situation for oral health in New Zealand. Our last dental health survey was in 2009, and I'm sad to say that it showed a measurable difference in the quality of our oral health in New Zealand than in Australia. We know that New Zealanders don't access dental care enough, and dental care is preventive. In 2018, the New Zealand Health Survey showed that only half of adults visited a dental healthcare worker in the past year.
