Tongue Thrust

A tongue thrust, which is one of many myofunctional disorders, is the habit of resting or moving the tongue between or against the teeth during rest, swallowing, and/or speech.

It may also be called reverse, immature, or infantile swallow, as it is the way that infants swallow until they grow out of it between 6 and 12 months of age.

Contributing factors may include:

  • Oral breathing
  • Low tongue posture
  • Upper airway obstruction
    (Nasal obstruction, enlarged tonsils & adenoids, etc.)
  • Tethered oral tissues
    (Tongue/lip ties)
  • Noxious oral habits
    (Thumb sucking, nail biting, etc.)
  • Bottle/sippy cup/pacifier use
  • Etc.


Tongue thrust may result in the following:

  • Malocclusion, misalignment of teeth, or open bite
  • Poor facial development
  • Headaches
  • TMJ pain
  • Orthodontic relapse
  • Speech misarticulation
  • Forward neck posture
  • Etc.
