signs & symptoms of omd

Symptoms of orofacial myofunctional disorders can be very obvious or happen over a period of time and be unclear.  Certain habits or conditions can interfere with proper actions of orofacial muscles causing OMD. These muscles include cheeks, jaw, lips and tongue. When these muscles function incorrectly due to habits or conditions, it can lead to improper development. This atypical development causes the muscles to have incorrect adaptations and not work in balance which can cause a variety of problems.
