INFLUENCE OF DELETERIOUS SUCKING HABITS ON THE DEVELOPMENT OF MALOCCLUSIONS IN CHILDHOOD

Abstract

Introduction: Deleterious sucking habits, such as thumb sucking and prolonged use of pacifiers and baby bottles, are associated with the development of craniofacial alterations and malocclusions during childhood. These habits may impair important functions of the stomatognathic system, including chewing, breathing, and speech. Objective: To analyze the influence of deleterious sucking habits on the development of malocclusions in children, highlighting their main impacts on orofacial growth. Methodology: This study consists of an integrative literature review conducted in the PubMed, SciELO, and Virtual Health Library (VHL) databases, using articles published between 2022 and 2026. Descriptors related to deleterious oral habits, non-nutritive sucking, and malocclusions were used. After applying the inclusion and exclusion criteria, the selected studies were qualitatively analyzed. Results: The studies demonstrated a strong association between non-nutritive sucking habits and occlusal alterations, especially anterior open bite, posterior crossbite, and dental protrusion. It was observed that the frequency, intensity, and duration of the habits directly influence the severity of the alterations. Discussion: The literature highlights the importance of early identification of these habits and multidisciplinary intervention to prevent functional, aesthetic, and emotional impairments related to child development. Final considerations: It is concluded that deleterious sucking habits negatively influence children’s orofacial development, making prevention and early intervention essential for the promotion of oral health.
