Orofacial Myofunctional Disorders (OMDs)

Orofacial Myofunctional Disorders (OMDs) are compensations we have adopted due to some kind of disruption within the development of the face, airway, and eruption of the teeth. These may include:

  • The tongue resting forward and low between or against the teeth
