The Impact of Breastfeeding and Non-Nutritive Sucking Behaviors on Skeletal and Dental Malocclusions of Pediatric Patients: A Narrative Review of the Literature

Studies suggest that breastfeeding can help resolve skeletal and dental malocclusions. But there is no clear evidence that breastfeeding duration affects skeletal or dental malocclusions in pediatric patients. Therefore, the objective of this narrative review was to review all the available updated articles on the impact of breastfeeding and non-nutritive sucking behaviors in deciduous and mixed teeth on different forms of malocclusions. The following electronic databases were used PubMed, Scopus, Web of Science, and Google Scholar to obtain relevant data that met the eligibility criteria. The studies in this narrative review were covered the last 10 years. Primary research identified 368 papers. In addition, three articles were selected from the gray literature for consideration. On the basis of duplication, title, abstract, methodology and/or irrelevant information, 177 articles were removed. This narrative review was focused on seventeen articles that met the eligibility criteria. When it comes to deciduous and mixed teeth, breastfeeding appears to decrease the occurrence of skeletal class II, posterior crossbite, and malocclusion. There appears to be a favorable correlation between prolong duration of breastfeeding and risk reduction. To avoid bias in the results, more longitudinal study is warranted, with data collected prospectively on the duration of exclusive breastfeeding and non-nutritive sucking behaviors, using specific survey questions, and subsequent clinical investigation of the occlusal status at the deciduous, mixed, and permanent teeth stages.
