For Aotearoa New Zealand (NZ) children, good oral health has become a luxury that most Māori and Pasifika children, and those of low socio-economic status, do not enjoy. By age 5 years, three out of five Māori, seven out of ten Pasifika and one out of three non-Māori/non-Pasifika children have already experienced dental caries (‘tooth decay’), making it the most prevalent non-communicable disease (NCD) in NZ children (Ministry of Health 2021a), as well as worldwide (Marcenes et al. 2013). Dental caries is the process by which the hard tissues of teeth are demineralised by organic acids arising from the microbial metabolism of dietary free sugars (Banerjee et al. 2020), resulting in carious lesions, popularly known as ‘cavities’. The term ‘early childhood caries’ (ECC) refers to the disease in the primary dentition in young children.
