Anterior open bite resulted from tongue thrusting in a 24 y.o. patient. Anterior upper teeth are not touching their counterpart.

[26] Lack of masticatory stress during development can cause tooth overcrowding. [37] [38] Children who chewed a hard resinous gum for two hours a day showed increased facial growth. [37]
These can be affected by tongue malfunction such as tongue thrust. Accordingly, treatment of tongue thrust is essential for treatment of speech disorders, and oral myology therapy aiming at tongue muscles training is an important part of speech therapy. [3] [non-primary source needed]
