tongue thrust is represented as a behavioural disturbance which can be taught to be resisted. Such interventional therapy is represented to strongly assist orthodontic or speech pathologist efforts at resolution of both the speech and orthodontic effects of anterior open bite and the associated lip incompetence of both. As with normal reflexes, most school-age children have tongue thrust if looked for. For example, according to recent literature, as many as 67–95 percent of children 5–8 years old exhibit tongue thrust, which may professionally be represented as associated with or contributing to an orthodontic or speech problem - depending on the clinical bias of proposal. Up to the age of four, as with the complex conversion of all simpler reflex events, there is a possibility that any observed child will normally outgrow tongue thrust as they transition to a fuller dentofacial development. However, if a tongue thrust pattern is retained beyond infancy, it can be seen through a lens of abnormality, and this vulnerable to clinical bias and attempts to clinically interact. Types of tongue thrusting include: Anterior thrust This is the most common type of tongue thrust. It is often associated with a low, forward tongue rest posture. Sometimes the tongue can be seen protruding beyond the lips at rest and/or during the swallow. Upper incisors can be extremely protruded and the lower incisors are pulled in by the lower lip. An anterior open bite is a common malocclusion associated with this type of tongue thrusting pattern, especially in the presence of lip incompetence. This type of thrust is most generally accompanied by a strong mentalis. Unilateral thrust This occurs when the tongue pushes unilaterally to the side between the back teeth during the swallow. The bite can be characteristically open on that side. Bilateral thrust This occurs when the tongue pushes between the back teeth on both sides during the swallow with the jaw partially or subtly open. Sometimes, the only teeth that touch are the molars, with the bite completely open on both sides including the anterior teeth. A large tongue can also be noted. This is the most difficult thrust to correct. Causes Factors that can contribute to tongue thrusting include macroglossia (enlarged tongue), thumb sucking, large tonsils, hereditary factors, ankyloglossia (tongue tie), and certain types of artificial nipples used in feeding infants, also allergies or nasal congestion can cause the tongue to lie low in the
