Influence of Oral Habits on Pediatric Malocclusion: Etiology and Preventive Approaches

Teeth malocclusion refers to the misalignment of teeth and improper occlusion of the upper and lower jaws when the mouth is closed, which can lead to both aesthetic and functional issues such as difficulties with chewing, biting, and speech. These challenges may further contribute to broader health concerns. One of the major contributing factors to malocclusion in children is the presence of certain oral habits. Research has established a strong association between habits such as thumb sucking, tongue thrusting, and mouth breathing and various malocclusion patterns, including anterior open bite, proclination, crowding, and posterior crossbite. This review seeks to examine these three primary deleterious oral habits, their impact on malocclusion, and effective prevention strategies to address these habits in pediatric patients.
