Correct swallowing depends on a proper relationship
between muscles of the face, mouth and throat.


An orofacial myofunctional disorder (OMD) is characterized by an abnormal lip, jaw, or tongue position during rest, swallowing, or speech. It can also include the presence of abnormal oral habits.

Orofacial Myofunctional Disorders

OMD can be caused by upper airway obstruction, chronic finger or thumb sucking, extended pacifier or bottle use, orofacial muscular and structural differences, and genetics.


Any habit or condition that interferes with proper development and action of the the orofacial muscles. This includes muscles of the tongue, lips, cheeks and jaw. Incorrect habits can lead to improper development.

Signs & Symptoms

  • Speech distortion; particularly a frontal lisp
  • Chronic open mouth positioning
  • Dental abnormalities; such as overjet and open bite
  • Tongue thrust: when the tongue pushes against or between the teeth during speech or swallowing.

What causes OMD?

Certain bottle feeding nipples, thumb sucking, nasal obstructions such as allergies, congestion swollen nasal passages; large tonsils & adenoids, short lingual frenum (tongue tied), muscular or other physiological abnormalities.

The following may cause OMD

  • allergies
  • enlarged tonsils and adenoids
  • excessive thumb or finger sucking, lip and fingernail biting, lip picking, and teeth clenching and grinding
  • family heredity


Most treatment programs are individualized and focus on tongue and facial resting postures, swallowing, and speech articulation. Children often need help and encouragement from their family to practice prescribed exercises.


The best outcomes are achieved when parents or guardians work with their child every day.
