# Upper airway constrictions (e.g., deviated nasal septum) or obstructions (e.g., enlarged tonsils) or infections (e.g., rhinitis) # General hypotonia or low body tone # Low-lying resting posture of the tongue # Imbalance in dental growth # Inadequate development of facial and cranial bones # Inappropriate development of muscles in the head and neck areas While identifying the causes of tongue thrust, it is important to remember that the resting posture of the tongue, jaw, and lips are crucial to the normal development of the mouth and its structures. If the tongue rests against the upper front teeth, the teeth may protrude forward, and adverse tongue pressure can restrict the development of the oral cavity. The tongue lies low in the mouth or oral cavity and is typically forwarded between upper and lower teeth. If tongue thrust behavior is not corrected, it may affect the normal dental development. The teeth may be pushed around in different directions during the growth of permanent teeth.
