Many parents are told their child may need braces one day, but fewer are told to look at the habits and muscle patterns that may be shaping the mouth, face, and airway long before orthodontic treatment begins. That is where myofunctional therapy can play an important role.
At The Dentist Lounge, we believe healthy development starts with function. The way a child breathes, swallows, rests their tongue, and uses the muscles of the face can all influence jaw growth, sleep quality, oral health, and even behavior. Myofunctional therapy helps address those patterns early so children have better support for healthy growth and long term wellness.
What Is Myofunctional Therapy?
Myofunctional therapy is a specialized form of therapy that focuses on the muscles of the mouth and face. It helps children learn healthier patterns related to tongue posture, swallowing, breathing, lip seal, and oral habits.
These patterns may seem small, but over time they can affect how the jaws develop, how the teeth come in, and how well a child breathes during the day and at night. If the tongue rests low in the mouth, if the lips stay open at rest, or if a child is consistently mouth breathing, those habits can influence facial growth in ways many parents do not realize.

Why Myofunctional Therapy Matters for Children
Children are still growing, which means function matters a great deal. The tongue is meant to rest against the palate, the lips are meant to stay together comfortably at rest, and breathing should ideally happen through the nose. When those patterns are not in place, the muscles of the mouth and face may not support normal development.
This can contribute to issues such as narrow dental arches, crowded teeth, poor sleep, mouth breathing, speech difficulties, swallowing problems, and changes in facial development over time. Myofunctional therapy helps support healthier patterns before those issues become more established.
Signs a Child May Benefit From Myofunctional Therapy
There are many reasons a child may be referred for myofunctional therapy. Some of the most common signs include:
- Mouth breathing during the day or at night
- Lips apart at rest
- Low tongue posture
- Tongue thrust when swallowing
- Speech concerns
- Snoring or restless sleep
- Crowded teeth
- Thumb sucking or prolonged pacifier habits
- Difficulty chewing well
- Open mouth posture
If these signs sound familiar, they may also overlap with the concerns discussed in Signs Your Child’s Jaw May Not Be Developing Properly. Many children do not have just one isolated issue. Instead, there is often a pattern involving oral habits, muscle function, breathing, and jaw growth.
The Connection Between Myofunctional Therapy and Mouth Breathing
One of the most common reasons children need myofunctional support is chronic mouth breathing. When a child breathes through their mouth regularly, the tongue usually sits low instead of resting against the palate. That can reduce the natural support the upper jaw needs during growth.
Over time, mouth breathing may contribute to a narrow palate, crowded teeth, changes in facial appearance, and sleep related issues. Myofunctional therapy can help reinforce healthier breathing and oral posture patterns as part of a bigger treatment plan.

How Tongue Posture Affects Jaw Development
The tongue is one of the most important guiding forces in oral development. When it rests properly against the roof of the mouth, it helps support the natural width and shape of the upper jaw. When it rests low in the mouth, that support is lost.
This is one reason proper tongue posture matters so much in childhood. A low resting tongue posture can contribute to a narrower palate, reduced space for teeth, and a less stable foundation for healthy airway function. Myofunctional therapy is designed to help retrain these patterns in a consistent, supportive way.
Myofunctional Therapy and Sleep
Children who do not breathe well often do not sleep well either. Poor oral posture, chronic mouth breathing, and airway related concerns can all affect sleep quality. A child may toss and turn, snore, grind their teeth, wake frequently, or seem tired during the day even when they appear to be getting enough hours of sleep.
Because sleep is so essential for growth, learning, mood, and healing, these signs should not be ignored. Myofunctional therapy does not replace airway evaluation or medical care, but it can be an important part of supporting better function and better sleep.

What Myofunctional Therapy Looks Like for Kids
Myofunctional therapy usually involves age appropriate exercises and guidance that help children improve oral muscle awareness and function. Depending on the child, therapy may focus on nasal breathing, tongue posture, lip seal, chewing, swallowing, and correcting habits that interfere with healthy development.
The process is not about forcing change overnight. It is about creating better patterns over time through repetition, support, and consistency. In some cases, therapy may be recommended alongside other treatments or referrals, especially if there are anatomical concerns such as enlarged tonsils, airway issues, or a tongue tie.
Why Early Intervention Matters
One of the greatest benefits of addressing these issues in childhood is that growth is still happening. That gives families a valuable opportunity to support better development before patterns become harder to change later on.
When myofunctional therapy is introduced early, it may help support more ideal jaw development, better breathing habits, improved sleep, and healthier oral function. This is one reason our approach at The Dentist Lounge emphasizes prevention and early awareness whenever possible.
How Myofunctional Therapy Fits Into a Bigger Picture
We do not look at myofunctional therapy as a standalone fix. Instead, we see it as one important part of a broader approach to growth, airway health, and development. Depending on the child’s needs, care may also include monitoring jaw growth, evaluating airway symptoms, addressing oral habits, or considering airway orthodontics when appropriate.
Some children may also need collaboration with other professionals, such as ENTs, speech language pathologists, sleep specialists, lactation consultants, or bodyworkers. The goal is always to understand the full picture and support the child as a whole.
When Parents Should Consider an Evaluation
If your child snores, mouth breathes, struggles with oral habits, has crowded teeth, or shows signs of poor oral posture, it may be worth exploring whether myofunctional therapy could help. Parents are often told to wait until braces are needed, but functional concerns can start much earlier than that.

Final Thoughts
Myofunctional therapy helps connect the dots between breathing, tongue posture, swallowing, sleep, and facial development. For many children, it can be an important step in supporting healthier growth and addressing patterns that might otherwise be overlooked.
At The Dentist Lounge, we believe these early signs matter. If you want to better understand how oral function may be affecting your child’s development, explore our Kids Growth & Development page, learn more about Myofunctional Therapy, or contact our team to schedule an evaluation.
