What was done
This narrative review synthesized biological mechanisms (the functional matrix principle and perioral neuromuscular patterns) and existing epidemiological evidence evaluating the impact of breastfeeding on infant craniofacial growth and malocclusion risk.
What was found
The abstract reports no numerical data. It qualitatively reports that breastfeeding is associated with a reduced risk of malocclusion (specifically anterior open bite and posterior crossbite) compared to formula feeding, with a dose-response relationship showing greater protection with longer breastfeeding duration.
Why it matters
The paper frames breastfeeding not only as nutritional support but as an early functional orthodontic intervention influencing jaw and palate development during a critical period of infant plasticity.
Limits
The paper is a narrative review with no original data or systematic search methodology. It also highlights methodological weaknesses in the existing literature, including diagnostic heterogeneity, variable definitions of breastfeeding duration, and confounding from pacifier use, non-nutritive sucking, and genetics.
