Orofacial Myofunctional Disorders are caused by improper position or function of the muscles of the mouth and/or face.  These improper positions of dental, skeletal and muscular structures may interfere with proper swallowing, speech or oral rest postures.

Some myofunctional habits include:

• Tongue Thrust – the improper placement and function of the tongue during swallowing.
• Abnormal Lip/Tongue Resting Positions – includes open lip posture and/or forward tongue posture.
• Oral Habits – thumb, finger or pacifier sucking beyond an appropriate age.

Why should OMD concern me?

These habits may negatively impact dental and/or facial growth patterns, including the eruption or alignment of teeth and/or jaws.  Unbalanced muscle pressures can undermine the overall stability of orthodontic treatment.  Speech patterns may become distorted due to incorrect positioning of the tongue.  Some indicators of a myofunctional problem include:

• Mouth breathing and nasal congestion without allergies.
• Open – mouth posture with lips a part and/or the tongue resting against the upper/lower teeth.
• Lips that are often cracked, chapped and sore from excessive licking.

When should therapy begin?

The age of the individual is not as important as their maturity level and the motivation to succeed.  Early intervention, such as elimination of sucking habits or sucking habits or assessment of other causative factors, may help prevent OMDs.  Children as young as five years may benefit from a comprehensive evaluation.  Therapy can begin as soon as all four upper front teeth have erupted.
