When your child rests, are his or her lips routinely apart? Does your child's tongue rest between or against the teeth? Does she or he have a tongue thrust? If your child has one of these or another harmful oral habit, then it may be time to call a speech-language pathologist or dental professional who is trained in the diagnosis and treatment of Orofacial Myofunctional Disorders (OMD).
Left untreated, an OMD could result in abnormalities in speech sound production, as well as improper alignment of teeth, periodontal disorders, orthodontic relapse, and abnormal jaw growth and position. More information is available from the International Association of Orofacial Myology.
