---

Myofunctional therapy is a supervised exercise program that retrains the muscles of the tongue, lips, and face. It also retrains the habits built on them: breathing, chewing, swallowing, and how your mouth rests. It runs for months, and it is not a procedure or a device.

The honest verdict is mixed. Adult studies point to modest benefit for snoring and sleep apnea alongside other treatment, the evidence thins out elsewhere, and tongue posture does not reshape an adult face.

## What Myofunctional Therapy Is and What It Aims For

Myofunctional therapy is retraining for oral and facial muscle patterns and the functions built on them. The American Speech-Language-Hearing Association puts the assessment and treatment of these disorders inside speech-language pathology scope of practice.

“Physical therapy for the muscles that surround and support the tongue” is how Priya Mistry, a dentist board-certified in dental sleep medicine, describes it. Like physical therapy, it is graded practice over time rather than a single visit.

### The Four Goals

Programs work toward four connected targets:

-   **Nasal breathing:** making the nose the default route for air, once the nasal airway itself is clear.
-   **Lip seal:** closed lips at rest, with the jaw relaxed rather than clenched.
-   **Tongue rest posture:** a stable, non-forward resting position with the tongue in contact with the palate.
-   **Swallowing:** a swallow without the tongue pushing between or against the front teeth.

Those four depend on each other, which is why a program takes months rather than weeks. A lip seal is hard to hold if the nose is blocked, and a swallow is hard to change if the tongue never rests on the palate.

If [mouth breathing](/oral-health/mouth-breathing/) is the reason you were referred, a medical or dental check for obstruction comes before any breathing exercise.

## What Myofunctional Therapy Is Used For

Four uses come up most often, and the evidence behind them is not equal.

| Use | What therapy targets | How strong the evidence is |
| --- | --- | --- |
| Tongue thrust | Forward tongue rest posture and a protrusive swallow | A conventional target, not ranked against the others |
| Mouth breathing | Mouth-open rest posture, after obstruction is ruled out | Sequencing is well supported, symptom change less so |
| Snoring and sleep apnea | Tone and coordination in the tongue and airway muscles | The strongest published signal, and still modest |
| Tongue tie | Tongue function before or after a surgical release | Small, mixed studies, added benefit still uncertain |

### Conditions With Weaker Evidence

You will also see myofunctional therapy advertised for temporomandibular disorder (TMD), and that use breaks down like this:

-   **The condition:** TMD is jaw joint and muscle pain, and it is the weakest use on the list.
-   **The gap:** tongue posture has not been established as a cause of TMD.
-   **Where it fits:** an optional add-on for diagnosed cases under dental supervision.

## Does Myofunctional Therapy Work for Sleep Apnea and Snoring

The current synthesis is modest, and the two numbers people quote sit a decade apart. Read the newer one first.

Published results point in the same direction with different strength:

-   **A 2026 overview of adult systematic reviews:** a drop of about 9.5 breathing interruptions per hour of sleep, along with lower daytime sleepiness scores.
-   **Quality of that evidence:** five of its nine included reviews were rated critically low quality, so read those numbers as a signal rather than a promise.
-   **Camacho’s 2015 meta-analysis:** before-and-after results from 120 adults, with roughly a 50 percent fall in breathing interruptions, which is a historical estimate rather than a result to expect.

Vik Veer, an ear, nose, and throat surgeon, notes that the throat exercises tested in trials are only one part of what myofunctional therapists do.

### Where Guidelines Stand

Guidelines have not moved to match the marketing. The American Academy of Sleep Medicine does not list myofunctional therapy as a recommended treatment category.

The American Academy of Dental Sleep Medicine looked at it directly in 2024 and called it uncertain as a stand-alone treatment.

### Use It Alongside Other Treatment

Pair myofunctional therapy with an established sleep apnea treatment, never in place of one:

-   Continuous positive airway pressure (CPAP), which keeps the airway open with air pressure
-   A custom [oral appliance](/dentistry/general/sleep-apnea/mouthguards/) that holds the lower jaw forward during sleep
-   Surgery on the tonsils, adenoids, or airway when a physician recommends it

Suspected [sleep apnea](/dentistry/general/sleep-apnea/) needs an evaluation with objective testing first.

## What Myofunctional Therapy Will Not Do

### Adult Facial Structure

It will not reshape an adult face. The American Association of Orthodontists says the evidence that tongue posture restructures the face is very weak.

Three limits follow from that:

-   **Skeletal problems:** meaningful adult skeletal problems are treated with orthodontic expansion or jaw surgery after a specialist assessment.
-   **Palate width:** no exercise widens a palate, which is what [palate expanders](/orthodontics/treatment/palate-expanders/) are for.
-   **Tooth position:** no exercise straightens teeth on its own.

### Mewing Versus Supervised Therapy

You may know the unsupervised version of this idea as [mewing](/blog/mewing/), a self-directed tongue-posture habit marketed on jawline appearance. This page is about the supervised clinical version.

The useful split: functional targets like swallowing, lip seal, and snoring carry no age limit, while changing the jaws themselves needs orthodontics or surgery.

## What a Program Looks Like and Who Provides It

Get the right evaluation before you book anything. A myofunctional therapist does not diagnose sleep apnea, a jaw disorder, or a blocked nose, so the order runs workup, then referral, then therapy.

Buying a program instead of a sleep study is the common way this goes wrong, and no exercise clears enlarged adenoids or a blocked nose.

### What a Program Includes

Individual practices publish their own process. One airway-focused dental practice describes a four-step program that runs like this:

-   **Assessment:** tongue function, lip seal, breathing, and swallowing.
-   **Plan:** a program built around what that assessment finds.
-   **Daily practice:** short routines at home, attached to an existing habit like brushing at bedtime.
-   **Follow-ups:** adjustments to the plan as coordination improves.
-   **Duration:** published sleep-apnea protocols ran roughly two to six months, most commonly around three.

Those durations are research doses. No authoritative source sets a standard clinic program length or visit schedule for adults.

That practice frames success as depending on frequency rather than session length. Expect the first few weeks to be the hardest, because coordination has to be relearned before anything feels automatic.

### Who Provides It

There is no license in myofunctional therapy itself, so three questions sort providers out:

-   **Base license:** ask what license the provider already holds, because the therapy sits on top of one.
-   **Training:** ask which course they finished and how their cases were supervised.
-   **Certification:** the International Association of Orofacial Myology’s Certified Orofacial Myologist requires a 28-hour course, supervised cases, an exam, and an onsite evaluation.

Scope is the part patients miss. “It’s not within my scope to treat TMD or to treat obstructive sleep apnea,” says Danielle Klee, a speech-language pathologist.

## Myofunctional Therapy for Tongue Tie and for Children

A tongue tie is a functional diagnosis, not one based on appearance. The American Academy of Otolaryngology defines it as limited tongue mobility caused by a restrictive band under the tongue.

Therapy is commonly used before or after a release, but the studies are small and mixed, and the added benefit over surgery alone stays uncertain. A [posterior tongue tie](/oral-health/posterior-tongue-tie/) is assessed by function, not by how the frenulum looks.

### Before and After a Surgical Release

One airway-focused practice requires therapy before a release for patients past infancy, reasoning that a tight tongue is also a weak tongue.

The same practice describes post-operative care running several weeks. What that care cannot claim is a lower reattachment rate, because controlled evidence does not establish one.

### For Children

Pediatric evidence is the thinnest part of this picture, and the American Academy of Dental Sleep Medicine’s 2024 consensus found it very limited.

One airway-focused practice runs a pediatric program on its own terms:

-   **Length:** 6 to 12 months.
-   **Who practices:** parents are taught the exercises for daily practice at home.
-   **Retention rationale:** a tongue resting on the palate is treated as a natural retainer after braces, which is that practice’s rationale rather than a proven outcome.

If your child snores, the [pediatric sleep apnea](/dentistry/pediatric/sleep-apnea/) workup is where to start.

## How Much Does Myofunctional Therapy Cost

### What Providers Charge

NewMouth checked seven US providers that publish cash prices, in September 2026. Their posted rates fell into four bands:

-   **Evaluations:** $195 to $450.
-   **Follow-up sessions:** about $100 to $200.
-   **Full guided programs:** roughly $1,800 to $4,595.
-   **Self-paced online program:** one started around $597.

That is a sample of providers who post prices, not a national average. The spread tracks service models more than region: a speech-language pathologist versus a hygienist, in person versus telehealth, guided versus self-paced.

### Insurance HSA and FSA

Insurance is not standardized. Coverage depends on the diagnosis, the service billed, the provider’s license, and your plan.

Whether a health savings account or flexible spending account applies depends on the expense qualifying as medical care under IRS rules.

Ask for the billing codes and a written treatment plan before you pay, and agree up front on what success looks like and when you will reassess.
