What to Do After Your Orthodontist Refers Your Child for Myofunctional Therapy
You left the orthodontist appointment with a referral slip for something called myofunctional therapy. Your child's ortho mentioned tongue posture, swallowing patterns, maybe mouth breathing. They said it could affect how the braces work. Now you are home, the slip is on the counter, and a week later you still are not sure what to do with it.
This is the most common situation I see as a myofunctional therapy specialist in Sandy Springs. The referral is real. The professional who gave it is credentialed. But the paper comes with no instructions, no urgency, and no clear path forward. So it waits while life continues.
This post exists to change that. Here is exactly what the referral means, why timing matters, and what happens when you actually make the call.
Why Orthodontists Refer for Myofunctional Therapy
Orthodontists straighten teeth using mechanical force. Braces, aligners, expanders, retainers. What they cannot do is retrain the muscles that work against that force every day.
The tongue rests in the mouth approximately 2,000 times per hour during swallowing. If it pushes forward against the front teeth or sits low in the mouth rather than resting on the roof, it creates constant pressure that works against alignment. No wire or bracket can compete with that. The teeth move into position and the tongue moves them back.
Mouth breathing creates a similar problem. Lips apart, tongue dropped, airway compensating. The resulting muscle patterns change how the face and palate develop, which affects how teeth come in and how well orthodontic results hold over time.
When an orthodontist refers your child for myofunctional therapy, they are saying: the mechanics alone will not hold unless we address the muscle patterns underneath. It is not a nice-to-have. It is a clinical observation about what will determine whether the treatment actually lasts.
What Myofunctional Therapy Actually Treats
Orofacial myofunctional therapy retrains the muscles of the mouth, tongue, and face to function correctly. The four core patterns it addresses are:
- Tongue thrust. The tongue pushes forward against or between the teeth during swallowing, rather than pressing up on the roof of the mouth.
- Low tongue posture. At rest, the tongue sits on the floor of the mouth instead of gently contacting the palate. This affects how the palate develops and how the airway is positioned.
- Mouth breathing. Habitual breathing through the mouth rather than the nose. Often connected to enlarged adenoids or tonsils, allergies, or learned patterns.
- Lip incompetence. The lips do not close naturally at rest, which alters facial muscle development and the position of the front teeth.
These are not behavioral problems. They are muscle patterns, often in place since infancy, that the child is simply not aware of. The therapy works through structured exercises and habit retraining over several months.
The Connection Between Tongue Habits and Orthodontic Results
Research on this has been consistent for decades. Children who complete myofunctional therapy before or during orthodontic treatment retain their results better than those who do not. The reason is mechanical: straight teeth held in place by muscles that support that position stay straight. Straight teeth held in place by a retainer while the tongue pushes against them relapse.
The orthodontist's referral is a clinical judgment about your child's specific situation. They saw a pattern in how your child's bite developed, how the palate is shaped, or how the teeth are moving, and they concluded that orthodontic mechanics alone will not produce a stable, lasting result. That judgment deserves to be acted on.
What Happens If You Wait
The most common thing that happens when the referral sits on the counter is that orthodontic treatment either gets delayed or proceeds without the muscle patterns being corrected. If treatment starts without addressing tongue thrust, the force applied by the tongue during swallowing continues to work against alignment. Some orthodontists will pause treatment, or will not start, until the myo evaluation is complete.
If braces are already on and the tongue habits are not addressed, the risk is relapse: teeth that drift back toward their original positions once the hardware is removed. Retainers help, but they are designed to maintain position, not to hold position against active muscle dysfunction.
The best time to act on the referral is before treatment starts. The second-best time is now, wherever you are in the process.
What to Expect at a Myofunctional Therapy Evaluation
The evaluation appointment is 60 to 90 minutes. It is not a commitment to begin treatment. It is a diagnostic session that tells both you and the therapist exactly what is present and what a treatment plan should look like.
At the end of the evaluation, I explain exactly what I found, what it means for your child's orthodontic situation, and what a realistic treatment plan looks like. You leave with a clear picture of what is involved before any commitment is made.
How Long Does Myofunctional Therapy Take?
A typical program runs 4 to 6 months, with sessions once or twice a week. Each session is 30 to 45 minutes. Between sessions, children complete daily exercises at home — usually 10 to 15 minutes, building habits through consistent repetition rather than intensive practice.
The length of the program depends on which patterns are present, how long they have been established, and how consistently the child completes the home exercises. Younger children (ages 6 to 10) often progress quickly because their patterns are less entrenched. Older children and adolescents can still achieve excellent results, but the habits have had more time to become automatic and take more deliberate work to replace.
What to Look for in a Myofunctional Therapist
Not every speech-language pathologist offers myofunctional therapy. When evaluating providers, ask whether myo therapy is a primary area of practice or an occasional add-on. For licensed SLPs, myofunctional therapy falls within scope of practice — what matters is that the clinician has dedicated training and treats it as a specialty, not a side service.
At Lasting Language Therapy, myofunctional therapy is one of the three core specialties the practice was built around, alongside Parkinson's voice rehabilitation and pediatric speech therapy. It is not something done occasionally alongside general caseload work.
The referral slip is not just a suggestion. Your orthodontist identified a clinical reason your child's results may not hold without addressing the muscle patterns underneath. The evaluation costs nothing but an hour of your time. What you learn from it determines whether the braces actually work long term.
