Hospital admissions for New Zealand children needing multiple teeth removed have risen sharply, prompting renewed calls for a levy on sugary products alongside preventive oral-health programmes.
New Zealand’s dental association has renewed its call for a sugar tax, saying worsening oral health among children is showing up in rising hospital extractions and placing avoidable pressure on the health system.
Figures cited by the association show children aged 0 to 14 were admitted on 7,973 occasions in the 2024-25 year to have more than one tooth removed, up from 7,351 the year before, 6,865 in 2022-23 and 5,540 in 2021-22. Robin Whyman, the association’s director of dental policy, said dental decay was driving the increase and argued that New Zealand should follow countries that already use taxes on sugary products to curb consumption.
Whyman said excessive sugar intake was closely linked to severe decay in young children, and that the problem was often concentrated in the three-to-eight age group. He said such levies could do more than raise prices by encouraging manufacturers to reformulate products with less sugar. Research published in 2022 in PubMed found no direct empirical studies proving oral-health benefits from sugar-sweetened beverage taxes, but said the overall evidence pointed to a likely positive effect.
The call also lands in a policy debate that has already been examined in New Zealand. A Treasury working paper in 2016 found a sugar tax could reduce obesity if set high enough and paired with wider measures, but warned it could have a regressive effect, hitting low-income households with children harder. Separately, analysis in the New Zealand Medical Journal has described dental caries as the most common non-communicable childhood disease in the country, with Māori and Pasifika children, lower-income families and those without access to community water fluoridation among the most affected.
In the UK, dental groups have argued that sugar-tax revenues should be used to improve oral health, including supervised toothbrushing in nurseries. That experience is one reason supporters in New Zealand say a tax should be tied not just to discouraging sugar consumption, but also to programmes that reduce tooth decay before children ever reach a hospital theatre.
