7. Causes tongue thrust
www.orthofree.com
• 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 normal
development of mouth and its structures. If 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
