“Myofunctional therapy” gets talked about everywhere—from orthodontics to sleep—often with big promises and vague definitions. Clinically, it’s much more specific:
Orofacial myofunctional therapy (OMT) is a structured therapy approach that targets how the muscles of the mouth and face function at rest and during key behaviors like breathing, swallowing, chewing, and speech.
ASHA describes orofacial myofunctional disorders (OMDs) as deficits involving oral and orofacial muscles that can interfere with structural growth, function, or development, and includes atypical tongue posture at rest and during swallowing/breathing/speech as part of the clinical picture.
This post covers:
- what myofunctional therapy is (and what it isn’t)
- who it’s for (kids and adults)
- the most common conditions it treats
- what a high-quality evaluation includes
- what therapy sessions look like and how long it takes
- how OMT fits into a coordinated ENT/dental/sleep plan
Quick Take
- Myofunctional therapy is most appropriate when symptoms reflect an OMD pattern: low tongue resting posture, open-mouth posture, weak lip seal, tongue thrust swallow, and related functional impacts.
- It’s not a substitute for medical care: if nasal obstruction, enlarged adenoids/tonsils, or sleep apnea is suspected, ENT/sleep evaluation is essential.
- Evidence suggests OMT can be a helpful adjunct for obstructive sleep apnea in some adults and children, but it’s not a stand-alone cure for everyone.
- The best OMT plans are measurable, skill-based, and paired with carryover routines (not just “exercises”).
What is myofunctional therapy?
Myofunctional therapy is a set of progressive exercises and habit-retraining strategies designed to improve:
- tongue resting posture
- lip seal and facial muscle balance
- nasal breathing habits (when airway patency is adequate)
- swallowing mechanics (e.g., reducing tongue thrust patterns)
- chewing efficiency and oral coordination
- related speech placement patterns when they co-occur (case-dependent)
ASHA’s public-facing overview states that OMDs are sometimes called “tongue thrust,” can affect eating/drinking/speaking, and that speech-language pathologists can help.
What myofunctional therapy is NOT
A lot of confusion comes from unrealistic or mismatched expectations. OMT is not:
- A way to “force” nasal breathing when the nose is obstructed
- A replacement for ENT care when adenoids/tonsils or nasal obstruction are drivers
- A replacement for sleep medicine when obstructive sleep apnea is suspected
- A quick fix without daily carryover (it’s motor learning)
It is a therapy tool that works best when the underlying airway and structural drivers are addressed and the client is able to practice consistently.
Who myofunctional therapy is for
Children (common profiles)
Myofunctional therapy may be considered when a child shows:
- chronic mouth-open posture and mouth breathing (outside acute illness)
- low tongue posture at rest
- tongue thrust swallow pattern
- messy eating, prolonged chewing, or inefficient oral control (case-dependent)
- orthodontic concerns where function is part of the stability plan
OMDs are described by ASHA as involving patterns that can interfere with normal growth, development, or function of orofacial structures.
Adults (common profiles)
Adults may benefit when they have:
- chronic mouth breathing and poor lip seal
- tongue posture issues that contribute to oral dryness or oral function complaints
- snoring or airway-related concerns where OMT is used as part of an airway plan
- TMJ-related orofacial tension patterns where orofacial therapy and habit retraining are part of a broader plan (with appropriate scope and diagnosis handled by qualified providers)
What myofunctional therapy treats (most common “buckets”)
1) Orofacial myofunctional disorders (OMD patterns)
This includes:
- low tongue resting posture
- open-mouth posture
- tongue protrusion during swallow (“tongue thrust”)
- imbalanced facial muscle patterns that affect function
This is the core clinical domain in the ASHA practice portal.
2) Mouth breathing patterns (when airway is addressed)
OMT can help retrain habits and posture that persist after obstruction is treated. It does not “fix” nasal blockage—so the evaluation must screen for obstruction first.
3) Sleep-disordered breathing adjunct (selected cases)
Systematic reviews and meta-analyses have investigated myofunctional therapy as an adjunct treatment for obstructive sleep apnea in adults and children.
Translation: OMT may improve certain sleep-related outcomes for some patients, but it’s generally positioned as part of a broader care plan (not a universal replacement for CPAP, ENT intervention, or other sleep treatments).
4) Orthodontic stability support (context-dependent)
In some cases, orthodontic providers refer for OMT when tongue posture and swallow patterns appear to be contributing to relapse risk. This is highly individualized and should be coordinated with the orthodontic plan.
5) Speech placement issues when co-occurring with OMD patterns
ASHA recognizes that OMDs can co-occur with speech sound disorders and that assessment/treatment is within SLP scope when appropriately trained.
Important nuance: OMT is not an automatic “fix” for articulation; it’s relevant when functional posture/swallow patterns are part of the same profile.
Decision Rules: Is myofunctional therapy a fit?
Likely a fit when:
- you can observe a consistent pattern: lips open at rest + low tongue posture + mouth breathing and/or tongue thrust swallow
- symptoms affect function: sleep quality, oral dryness, chewing/swallow efficiency, orthodontic stability, or related speech patterns
- airway obstruction has been evaluated or is being evaluated in parallel
Not the right first step when:
- nasal obstruction is significant and untreated (therapy can’t breathe through a blocked nose)
- sleep apnea is suspected but not evaluated (therapy should not delay medical assessment)
- the main issue is purely dental alignment without functional pattern concerns
What to expect in an evaluation
A high-quality myofunctional evaluation typically includes:
1) History and symptom pattern mapping
- mouth breathing (day/night), snoring, sleep quality
- allergies/congestion history
- feeding history (kids), chewing endurance
- orthodontic timeline and concerns
- speech/voice history as relevant
2) Rest posture assessment
- lip seal at rest (strain vs easy closure)
- tongue rest position (low/forward vs palate contact patterns)
- nasal vs oral airflow at rest
3) Functional assessment
- swallow pattern (tongue thrust signs)
- chewing and bolus management
- speech placement screening (when indicated)
4) Referral triggers
Clinicians should explicitly identify when ENT/sleep/dental evaluations are needed. Cleveland Clinic notes that providers with special training (including SLPs among other disciplines) perform myofunctional therapy—underscoring the importance of correct provider training and interprofessional coordination.
What therapy sessions look like
Core components
Most effective programs include:
1) Skill training (not just “strength”)
- tongue-to-palate placement drills (as appropriate)
- lip seal endurance and control (without compensatory jaw tension)
- nasal breathing habit training after airway patency is confirmed
- swallow retraining with functional cueing
2) Daily carryover plan
OMT is motor learning. Typical programs depend on:
- brief daily practice
- specific “at rest” cues (screens, car rides, homework time)
- mealtime routines and reminders (without nagging)
3) Progression and measurement
You should see measurable changes such as:
- increased closed-lip rest time
- more consistent tongue resting posture
- improved swallow pattern consistency
- reduced mouth-breathing time (when airway allows)
- improved symptom outcomes tied to your goals (dry mouth, snoring reports, etc.)
How long does myofunctional therapy take?
Timelines vary based on:
- age
- severity of pattern and habit strength
- whether obstruction is addressed
- consistency of home carryover
A practical expectation is weeks to months, not days—because this is retraining a default posture used thousands of times per day.
Symptom → Action Map
| If you notice… | Most likely driver | Best next step |
| Mouth open at rest + chronic congestion | nasal obstruction | ENT/allergy evaluation + OMD screening |
| Tongue thrust swallow + orthodontic relapse concerns | OMD pattern | SLP myofunctional evaluation + ortho coordination |
| Snoring + daytime fatigue | possible sleep-disordered breathing | sleep medicine/ENT evaluation; consider OMT as adjunct |
| Low tongue posture + dry mouth on waking | nighttime mouth opening | airway evaluation + OMT habit plan |
| Speech sound distortions + OMD signs | co-occurring patterns | integrated speech + OMD therapy plan |
What to ask your provider
- What is the primary driver: obstruction/airway, learned posture, swallow pattern, or combination?
- Do we need ENT or sleep evaluation before starting (or in parallel)?
- What are the top 2–3 measurable goals for the next 6–8 weeks?
- What does the daily home plan look like (minutes/day, when, and how we’ll track)?
- If the goal includes sleep symptoms, how will outcomes be monitored with the medical team (without overpromising)?

FAQ: Myofunctional Therapy
What is myofunctional therapy?
Myofunctional therapy (often called orofacial myofunctional therapy, OMT) is therapy that targets tongue posture, lip seal, swallowing patterns, and related breathing habits when they reflect an orofacial myofunctional disorder.
Who performs myofunctional therapy?
Providers with specialized training in OMDs may provide myofunctional therapy; speech-language pathologists are commonly involved when OMD patterns affect swallowing, speech, or functional oral posture.
What does myofunctional therapy treat?
Common targets include tongue thrust/OMDs, mouth-breathing posture patterns (when airway is addressed), swallow retraining, and related functional issues.
Does myofunctional therapy help sleep apnea?
Research has evaluated OMT as an adjunct treatment for obstructive sleep apnea in adults and children. It may help some patients, but it is not a universal stand-alone replacement for medical sleep apnea treatments.
How long does myofunctional therapy take?
It varies, but most programs require weeks to months because the goal is retraining default posture and swallow patterns with consistent daily carryover.
Do I need ENT evaluation before myofunctional therapy?
If nasal obstruction, enlarged adenoids/tonsils, or sleep-disordered breathing is suspected, ENT/sleep evaluation is important because therapy can’t correct a blocked airway.
