Early childhood caries (ECC) remains a significant global health challenge, disproportionately affecting marginalized populations. While traditional research emphasizes behavioral and biological risk factors, emerging evidence highlights the critical role of environmental determinants. This narrative synthesis aims to highlight the role of environmental determinants as a risk factor for ECC pathogenesis. Environmental toxins (e.g., lead, perfluoroalkyl acids, tobacco smoke, air pollution) disrupt enamel development, impair salivary function, and compromise immune responses, directly increasing caries susceptibility. Environmental degradation, including air pollution, reduces ultraviolet B radiation exposure, limiting endogenous vitamin D synthesis that is vital for enamel mineralization and immune regulation. These risks are compounded in low- and middle-income countries, where structural inequities, inadequate sanitation, and climate disruptions exacerbate ECC burdens. We introduce ecovitality—the resilience of ecosystems supporting human health—as a novel framework linking ecological vitality to oral health. Degraded environments limit access to fluoridated water and nutrient-dense foods while promoting sugary diets and endocrine disruptors. A One Health approach is advocated to address interconnected environmental, social, and biological determinants of the risk for ECC. Despite global reductions in tobacco use and lead exposure, the Global Burden of Disease 2021 analysis reports stagnation in ECC prevalence. This underscores the critical need for longitudinal and mechanistic studies to establish causality, quantify the contributions of environmental controls, and explore how mitigating these risks can reduce the global ECC burden. Such evidence may promote interdisciplinary action to align oral health promotion for children with the Sustainable Development Goals. Full article
