What Is Myofunctional Therapy and How Can It Help Your Child?
Posted on (not posted yet) by NC Pediatric Dentistry |
 Myofunctional therapy is a specialized form of exercise therapy that retrains the muscles of the face, tongue, and mouth to function the way they should. If your child deals with mouth breathing, a tongue thrust, difficulty swallowing, or speech challenges, this type of therapy may be part of the solution. It’s a topic more North Carolina parents are asking about, and for good reason: the way a child’s oral muscles work during rest, eating, and sleeping can shape everything from jaw development to airway health.
This guide explains what myofunctional therapy involves, who it helps, and how it connects to your child’s overall pediatric dental care. You can learn more about how NC Pediatric Dentistry supports families across the state on our homepage.

Understanding Myofunctional Therapy
At its core, myofunctional therapy focuses on correcting improper oral muscle habits. The exercises target tongue posture, swallowing patterns, lip closure, and nasal breathing. Think of it like physical therapy, but for the muscles in and around the mouth.
When everything works correctly, the tongue rests against the roof of the mouth, the lips stay sealed at rest, and swallowing happens with a smooth wave-like motion that doesn’t push the tongue forward against the teeth. In many children, though, one or more of these patterns is off. The tongue may sit low in the mouth, the lips may hang open, or the child may thrust the tongue forward every time they swallow. Over hundreds of swallows per day, these small deviations create real consequences.
Myofunctional therapy was developed by speech and dental professionals who recognized that many structural and orthodontic issues trace back to how the muscles function during everyday activities.
Signs Your Child May Benefit From Myofunctional Therapy
Not every child needs this type of therapy, but certain patterns are strong indicators. A child who breathes through the mouth during the day and at night, especially if they snore or sleep restlessly, may have oral muscle dysfunction contributing to the problem.
Other signs include a noticeable tongue thrust when swallowing (you can sometimes see the tongue push forward against or between the front teeth), difficulty chewing or a preference for soft foods, and persistent thumb or finger sucking past age 4. Speech sound errors that don’t respond well to traditional speech therapy alone can also point toward underlying muscle issues.
Children who have had a tongue tie or lip tie released may benefit from myofunctional therapy as part of their recovery. The frenectomy removes the restriction, but the muscles still need retraining because they’ve spent months or years compensating for limited movement.
What to Expect During Treatment
Myofunctional therapy is typically provided by a certified myofunctional therapist, which may be a speech-language pathologist or a dental hygienist with specialized training. Sessions are usually weekly and last about 30 minutes. A full course of therapy often spans 6–12 months, depending on the severity of the issues and the child’s age.
Each session introduces specific exercises that the child practices daily at home. Early exercises might focus on basic awareness: where does the tongue rest? Can the child keep their lips sealed for a set amount of time? As skills build, the exercises become more targeted, working on proper swallowing technique and nasal breathing habits during different activities.
Consistency matters more than intensity. The exercises themselves are simple, but doing them regularly is what creates lasting change. Most therapists use games, stickers, or tracking charts to keep younger children engaged.
How Myofunctional Therapy Connects to Dental Health
The connection between oral muscle function and dental development is significant. A tongue that rests low or thrusts forward can push teeth out of alignment, contribute to an open bite, and prevent the upper jaw from widening naturally. These are issues that often lead to orthodontic treatment down the road.
When myofunctional therapy corrects these patterns early, it can reduce the severity of orthodontic problems or, in some cases, help prevent them. It also supports better outcomes for children who do need braces or expanders, because the muscles are working with the treatment instead of against it.
From a broader health perspective, retraining a child to breathe through the nose improves oxygen exchange, supports better sleep quality, and reduces the dry mouth conditions that raise cavity risk. Our team at NC Pediatric Dentistry considers the whole picture when evaluating a child’s oral health, and muscle function is an important part of that picture.
Taking the First Step
If you think your child might benefit from myofunctional therapy, start by bringing it up at their next dental appointment. Our team can assess tongue posture, breathing patterns, and swallowing habits during a routine visit and help determine whether a referral makes sense. NC Pediatric Dentistry serves families across North Carolina. Visit our locations page to find an office near you and schedule an appointment.
Frequently Asked Questions
What age is best to start myofunctional therapy?
Most therapists work with children ages 4 and up, since the exercises require some ability to follow instructions and practice independently. However, older children and even teenagers can still see significant benefits.
Is myofunctional therapy the same as speech therapy?
They overlap but aren’t identical. Speech therapy focuses on sound production and language skills, while myofunctional therapy targets the underlying muscle patterns that affect tongue posture, swallowing, and breathing. Some speech therapists are also trained in myofunctional therapy.
Does insurance cover myofunctional therapy?
Coverage varies by plan and provider. Some medical and dental insurance plans cover myofunctional therapy when it’s prescribed for a diagnosed condition. Check with your insurance provider for details specific to your plan.
Can myofunctional therapy help with thumb sucking?
Yes. Myofunctional therapy addresses the oral habits and muscle patterns that often drive prolonged thumb or finger sucking. By retraining resting tongue posture and improving lip seal, the need for the sucking habit often diminishes naturally.
Will my child need a frenectomy before starting therapy?
If a tongue tie or lip tie is restricting movement, releasing it first gives the exercises a better chance of success. Your child’s therapist and pediatric dentist can work together to determine the right sequence of treatment.
