A recent study has revealed a significant association between high birth weight and the risk of early childhood tooth decay (ECC) (Wang, H., Zhang, H., Zeng, X. et al. Association between high birth weight and dental caries at 4–5 years of age: a birth-cohort study. BMC Oral Health 24, 896 2024). Researchers from the Shanghai Stomatological Hospital & School of Stomatology in China analyzed data from 491 children aged 4 to 5 years old and found that children born weighing 4,000 grams (8.8 pounds) or more were more likely to develop ECC compared to those with normal birth weight.
ECC is when there is a presence of one or more decayed, missing, and filled tooth surfaces in any primary tooth in a child less than 71 months old. The study was designed as a retrospective longitudinal register-based cohort study that included pregnant women in their first trimester between June 2012 and March 2013. The children underwent regular physical examinations, including oral checkups and their caries experience was measured.
The study found that high birth weight was also associated with a higher risk of severe caries, defined as having three or more decayed, missing, or filled teeth. These findings suggest that high birth weight can be considered a predictor for ECC and should be factored into risk assessments to prevent dental problems.

The researchers suggest that early intervention is crucial for preventing ECC in children born with high birth weight. Dentists and healthcare providers can use this information to identify children at risk and implement preventive measures, such as regular dental checkups, oral hygiene education, and dietary guidance.
While the exact mechanisms linking high birth weight to ECC are still unclear, this study provides valuable insights into the potential risk factors for this common childhood disease. By recognizing the association between high birth weight and ECC, healthcare providers can take proactive steps to protect the oral health of children and improve their overall well-being.
