Tongue thrust is an unconscious behavior pattern. The tongue pushes at the front teeth during speech, swallowing and when resting. This thrusting pattern can contribute to speech or orthodontic issues.
Other additional factors may be allergies and nasal congestion, enlarged tongue, open mouth posture, thumb sucking and tongue tie. Incorrect tongue position can cause airway problems during sleep, dental problems, headaches, orthodontic relapse, posture issues, speech delays and stomach distress from swallowing air.
Through orofacial myofunctional therapy and the proper outside referrals, the tongue can be retrained to rest in a proper position.
