Myofunctional Therapy: Know What to Expect and When It May Help

Can you breathe comfortably through your nose, keep your lips together at rest, and swallow without your tongue pushing forward? These habits involve a team of muscles in the mouth and face. Myofunctional therapy uses guided practice to improve how those muscles work during rest and daily activities.

It may help with certain oral habits, swallowing patterns, or speech concerns. It isn’t a guaranteed way to change your jaw or teeth, and it can’t treat a blocked airway or sleep apnea on its own. An assessment helps show whether therapy fits your needs and whether other care should come first.

What myofunctional therapy trains

How oral habits work together

The tongue, lips, and jaw work together when you breathe, chew, swallow, and speak. Their position at rest matters too. A clinician may look at whether your lips rest comfortably together, where your tongue sits, and whether you can breathe through your nose without strain.

Treatment goals depend on the person. Therapy may focus on noticing resting posture, improving muscle coordination, or practicing a more functional swallow. There’s no single exercise plan that suits everyone.

What an orofacial myofunctional disorder means

An orofacial myofunctional disorder, or OMD, involves an atypical pattern of movement or posture in the mouth and face. It may affect tongue position at rest or during swallowing, breathing, or speech. The ASHA Orofacial Myofunctional Disorders Practice Portal describes clinical signs, assessment, and team-based care.

An observed habit alone doesn’t confirm a disorder. A trained clinician considers the person’s age, function, health, and oral structures before deciding whether treatment is needed.

What therapy can’t promise

Myofunctional therapy isn’t a proven way to reshape the jaw, straighten teeth, or remove a physical blockage in the nose. Dental or structural concerns may need care from a dentist, orthodontist, or medical specialist. Therapy also can’t be counted on to cure sleep apnea.

Signs that may warrant an assessment

Resting posture and breathing

Persistent open-mouth posture or trouble keeping the lips together at rest may be worth discussing with a clinician. These signs can have different causes, including nasal congestion, allergies, or enlarged tissues. For some people, lip closure is difficult because nasal breathing is restricted.

Don’t force the lips closed if breathing through the nose feels hard. A medical clinician, such as an ear, nose, and throat specialist or allergist, can assess possible causes.

Swallowing, chewing, and speech

A clinician may assess a tongue that pushes between the teeth during swallowing, trouble managing food, or chewing that feels difficult. Some speech sound concerns may also involve tongue or lip placement. These signs can occur for different reasons, so they don’t confirm an OMD by themselves.

A speech-language pathologist (SLP) can assess speech and swallowing needs and decide whether myofunctional therapy may help. Other treatment may be needed too.

When referrals come up

A child with an open-mouth resting posture may be referred for an assessment. A person with a swallowing concern may see an SLP, while an adult with signs of sleep-disordered breathing may start with a sleep clinician. A referral is a request to look more closely, not a diagnosis or a promise that therapy will be recommended.

What assessment and therapy involve

What a full assessment may include

The clinician may ask about medical and dental history, breathing, oral habits, and the concern that led to the visit. They may observe tongue and lip movement, resting posture, swallowing, chewing, and speech when relevant. The scope depends on the person’s needs.

If the assessment raises concerns about nasal breathing, teeth, oral structures, or sleep, the clinician may suggest another evaluation. ASHA notes that OMD care often involves collaboration among SLPs, medical professionals, and dental or orthodontic providers.

How sessions build skills

If therapy is appropriate, sessions may include guided practice and exercises tied to daily functions. A clinician might work on tongue or lip movement, resting posture, or a specific swallowing pattern. The plan should match the person’s age, ability, and goals.

Ask how each activity connects to the goal you’re working on. A set of exercises from a friend or an online video may not fit your needs.

Why home practice matters

Many treatment plans include practice between appointments. Before leaving a session, make sure you know what each activity is for and how to do it correctly. Ask how often to practice and what to do if an exercise causes discomfort.

A brief note about practice, questions, or changes in the target function can help guide the next appointment. Tell the clinician if the plan feels hard to fit into daily life.

What the evidence says and why team care matters

What research can tell us

Researchers have studied myofunctional therapy for several concerns, including sleep apnea, but the findings don’t establish the same benefit for every person or condition. A 2024 review of seven randomized trials involving 310 people reported improvements in some sleep measures among adults. The review also noted limited evidence on long-term effects; the single included pediatric trial found no improvement in key sleep outcomes and reported low adherence. Read the systematic review and meta-analysis for its methods and findings.

Results from a small set of studies don’t prove that therapy works for everyone. Treatment plans and study methods vary, so expected benefits should be discussed with the clinician who knows your case.

Why sleep apnea needs medical care

Obstructive sleep apnea is a medical condition that needs assessment by a qualified medical professional. Myofunctional therapy may be considered as part of care in some cases, but it shouldn’t replace diagnosis or a recommended treatment such as positive airway pressure (PAP). Don’t stop or change prescribed treatment without speaking with your sleep clinician.

The American Academy of Sleep Medicine’s practice guidelines cover evaluation and treatment of sleep disorders. A sleep clinician can explain which tests and treatments fit your situation.

When several clinicians are involved

The right team depends on the concern. An SLP may assess speech or swallowing, while a dentist or orthodontist may address dental alignment or bite issues. An ENT specialist or allergist may assess problems that affect nasal breathing, and a sleep clinician can evaluate suspected sleep apnea.

Treating an airway, dental, or structural issue may be needed before or alongside therapy. Ask your providers to share relevant findings and agree on goals.

Choose a qualified therapist and make goals practical

Questions to ask before starting

Ask about the provider’s training, license, and experience with your concern. Find out what the assessment includes, how progress will be measured, and how often you’ll practice at home. It’s also fair to ask how the therapist coordinates care with your dentist, doctor, or other providers.

Bring useful records, such as dental notes or sleep evaluation results. Knowing what has already been checked can help the team set clear next steps.

Turn the plan into a routine

Choose a practice schedule with your clinician that you can maintain. Follow the instructions, note changes in the function you’re working on, and raise discomfort or barriers early. Progress should be reviewed against your own goals, not a promise of a cure.

Conclusion

Myofunctional therapy focuses on muscle coordination and habits related to resting posture, swallowing, breathing, or speech. An assessment is needed to decide whether it’s suitable, and medical or structural concerns may need separate care. If you’re noticing a persistent problem, start by discussing it with a qualified clinician and ask what evaluations should come before therapy.
