Signs and Symptoms

A speech-language pathologist assesses the structures and the way the lip, cheeks, teeth, jaws and tongue move. This is done by watching the child speak and also watching how he or she swallows foods and liquids. Pictures are taken to record the child's dental structures. The speech-language pathologist may recommend the child see an an allergy doctor, ENT doctor, or orthodontist.
Each child’s treatment program is different and focuses on:
- Tongue and facial resting postures
- Speech sound production
Children often need help and encouragement to practice their treatment exercises. You will see the best results when the family works with their child every day.
As a national leader in pediatric speech-language pathology, Cincinnati Children's has a program for OMD. This program is staffed by speech-language pathologists who have special training in the evaluation and treatment of OMD. Patients who have this disorder are often referred by orthodontists, dentists, and other speech-language pathologists. We welcome referrals from primary care providers and specialty doctors.
