Introduction to Tongue Thrust - Tongue thrusting is described as a pathological event by dental and speech pathologist professionals. - It is believed to cause anterior open bite, incompetent lip seal, and speech and swallowing issues. - Interventional therapy can help resolve these effects. - Most school-age children exhibit tongue thrusting. - Tongue thrusting can be seen as abnormal if it persists beyond infancy.

Types and Causes of Tongue Thrust - Anterior thrust: most common type, associated with low, forward tongue rest posture, protrusion of tongue beyond lips, and anterior open bite. - Unilateral thrust: tongue pushes unilaterally to the side between back teeth, causing characteristic open bite on that side. - Bilateral thrust: tongue pushes between back teeth on both sides, with partially open jaw and sometimes only molars touching. - Large tongue can also be noted in bilateral thrust. - Bilateral thrust is the most difficult to correct. - Factors include macroglossia (enlarged tongue), thumb sucking, large tonsils, hereditary factors, ankyloglossia (tongue tie), and certain types of artificial nipples. - Allergies or nasal congestion can also contribute to tongue thrusting by obstructing breathing.

Effects of Tongue Thrust - Tongue thrusting can affect teeth alignment and contribute to malocclusion and open bites. - Continuous pressure from tongue thrusting can force teeth out of alignment and reverse orthodontic work. - Tongue thrusting can distort certain speech sounds produced by placing the tongue on the upper alveolar ridge. - Chewing and swallowing with tongue thrusting is less effective than normal motion. - Speech and orthodontic treatment may relapse if tongue thrusting is not addressed.

Treatment Options for Tongue Thrust - Orthodontic spikes, prongs, or other tongue reminders can redirect tongue rest posture and swallow. - Orofacial myofunctional therapists teach oral rest posture and proper chewing/swallowing mechanics without appliances.
