If your child’s dentist or pediatrician has mentioned myofunctional therapy, you’re probably wondering what it actually involves – and whether it’s really necessary. Myofunctional therapy is a specialized form of treatment that targets the muscles of the face, mouth, and throat to correct patterns that can affect breathing, sleep, speech, and even the way a child’s face and jaw develop over time.
For parents navigating a new diagnosis or recommendation, it helps to understand exactly what this therapy is, why it matters, and what the process looks like from start to finish.
What Is Myofunctional Therapy?
Myofunctional therapy is a series of targeted exercises designed to retrain the muscles of the tongue, lips, cheeks, and jaw. The goal is to correct what’s known as orofacial myofunctional disorders (OMDs) – patterns like improper tongue posture, mouth breathing, or incorrect swallowing habits that can interfere with normal growth and function. If you want to try some of the foundational movements yourself, we’ve put together a full walkthrough of myofunctional therapy exercises you can start at home.
Unlike orthodontics, which primarily addresses the position of the teeth, myofunctional therapy addresses the underlying muscle function that often contributes to the problem in the first place. Many dental professionals view the two as complementary – orthodontics can straighten teeth, but without correcting the muscle patterns that misaligned them, relapse is common.
Signs Your Child May Benefit from Myofunctional Therapy
Orofacial myofunctional disorders can be subtle, and many parents don’t realize their child is affected until a dental or medical provider points it out. Common signs include:
- Chronic mouth breathing, especially during sleep
- Tongue resting low in the mouth instead of against the roof
- Reverse or tongue-thrust swallowing patterns
- Snoring or restless sleep
- Speech difficulties, particularly with certain sounds
- Prolonged thumb-sucking or pacifier use past toddler years
- Narrow dental arches or crowded teeth
If several of these sound familiar, it doesn’t necessarily mean therapy is required – but it’s worth bringing up at your child’s next dental visit. We’ve written a more detailed breakdown of these signs in Signs Your Child May Need Myofunctional Therapy, including what to watch for at different ages.
Why Muscle Function Matters for Growth
The Tongue’s Role in Facial Development
The tongue plays a much bigger role in facial growth than most parents realize. When resting correctly, the tongue sits against the roof of the mouth, gently guiding the upper jaw to widen as a child grows. When the tongue rests low – often due to mouth breathing or tongue-tie – the upper jaw can develop narrower than it should, which is frequently linked to crowded teeth and airway restriction later on. This same low-resting tongue posture is closely related to a specific pattern called tongue thrust, which we cover in What Is Tongue Thrust? Signs, Causes, and Treatment.
The Connection to Breathing and Sleep
Muscle function and airway health are closely linked. Children who breathe through their mouths rather than their noses may be more prone to disrupted sleep, and in some cases, this pattern is associated with pediatric sleep-disordered breathing. Myofunctional therapy aims to help retrain nasal breathing and proper tongue posture, which can support healthier sleep patterns over time. For a deeper look at this connection, including what the research shows, see Myofunctional Therapy for Sleep Apnea: Does It Help?
The Connection to Speech
Because the tongue and surrounding muscles play a direct role in forming sounds, unresolved myofunctional disorders can also show up as speech difficulties, particularly with sounds like s, r, l, and th. Many speech therapists coordinate directly with myofunctional providers for this reason. We go into more detail in How Myofunctional Therapy Helps with Speech Delays.
What Happens During Myofunctional Therapy?
Treatment typically involves a series of guided exercises, often taught by a trained myofunctional therapist or dentist with specialized certification. A typical program may include:
- An initial evaluation to assess tongue posture, swallowing pattern, breathing habits, and any structural factors (such as tongue-tie) that may need to be addressed first
- Individualized exercises targeting the tongue, lips, and cheek muscles, usually practiced daily at home
- Regular follow-up visits to track progress and adjust the exercise plan
- Coordination with other providers, such as an orthodontist, ENT, or speech therapist, when needed
Most programs run several months, with consistency at home being one of the biggest factors in success. If you’re ready to schedule an evaluation, our guide to what happens at your first visit walks through the process from intake to your first set of exercises.
Myofunctional Therapy for Different Ages
While myofunctional therapy is often associated with young children, it isn’t limited to any one age group. Older children, teens, and even adults can benefit – particularly if underlying muscle patterns weren’t addressed earlier and are contributing to ongoing issues like orthodontic relapse, TMJ discomfort, or poor sleep quality. We cover this in more depth in Does Myofunctional Therapy Work for Adults?
Is Myofunctional Therapy Evidence-Based?
It’s a fair question, and one we hear often. Myofunctional therapy has a growing body of research behind it, particularly around its role in supporting nasal breathing, swallowing patterns, and sleep-disordered breathing, though outcomes depend heavily on consistency and the specific disorder being treated. We’ve dedicated a full article to this question, including what the current research actually says, in Is Myofunctional Therapy Legit? What the Research Says.
How Much Does Myofunctional Therapy Cost?
Cost is one of the most common questions we get, and it varies depending on the length of the program, whether structural issues like tongue-tie need to be addressed first, and your insurance coverage. Some plans offer partial coverage, particularly when therapy is tied to a documented medical need like sleep apnea or a diagnosed swallowing disorder. For a full breakdown of typical costs and how insurance coverage works, see How Much Does Myofunctional Therapy Cost? Insurance and Payment Options.
How to Get Started
If you suspect your child may have an orofacial myofunctional disorder, the first step is an evaluation with a dentist or therapist trained in this area. They can assess whether therapy is appropriate, identify any structural issues (like tongue-tie) that may need treatment first, and build a plan tailored to your child’s specific needs.

Frequently Asked Questions
Is myofunctional therapy painful?
No. The exercises involve gentle, repetitive muscle training and are not painful, though they do require consistency and practice.
How long does myofunctional therapy take to work?
Timelines vary by individual, but many programs last several months, with noticeable changes in habits often emerging within the first few weeks of consistent practice.
Can myofunctional therapy replace orthodontic treatment?
Not typically. The two are often used together – myofunctional therapy addresses muscle function, while orthodontics addresses tooth and jaw alignment.
