What Is It?
Tongue thrust is when a person’s tongue pushes (thrusts) up against the teeth or between the front teeth while at rest, speaking, or while swallowing.
The constant pressure or thrust from the tongue forces the teeth and arch out of alignment and creates a gap, or open bite between top and bottom teeth.
Untreated tongue thrust can lead to long-term damage to speech, like a lisp over certain sounds.
Can tongue thrust be corrected?
Yes! The most successful treatment for adults and children is myofunctional therapy. Myofunctional therapy helps with proper tongue and lip posture when at rest, and jaw stability which leads to correction of swallowing habits and open mouth posture. Tongue thrust has high success rate if treated.
