What Is Myofunctional Therapy? A Parent's Complete Guide

If you've been told your child has a "tongue thrust," breathes through their mouth, snores at night, or has trouble with certain speech sounds, you may have come across the term myofunctional therapy. But what exactly is it, and how can it help your child?

As a speech-language pathologist specializing in orofacial myofunctional disorders, I've seen firsthand how this targeted therapy can transform breathing, sleep, speech, and even facial development. Let me walk you through everything you need to know.

What Is Myofunctional Therapy?

Myofunctional therapy is a specialized form of therapy that focuses on the muscles and functions of the face and mouth — specifically the tongue, lips, cheeks, and jaw. Think of it as physical therapy for your mouth.

The goal is to retrain incorrect muscle patterns and establish proper:

• Tongue resting posture — where the tongue sits when you're not eating or speaking
• Swallowing patterns — how you swallow food and saliva
• Breathing patterns — nasal vs. mouth breathing
• Lip seal — keeping the lips comfortably closed at rest

These might sound like small things, but they have a huge impact on speech, dental health, sleep quality, facial growth, and overall well-being.

What Are Orofacial Myofunctional Disorders (OMDs)?

Orofacial Myofunctional Disorders (OMDs) are patterns of muscle activity in the face and mouth that interfere with normal growth, development, or function. Common OMDs include:

• Tongue thrust — pushing the tongue forward during swallowing or at rest
• Mouth breathing — habitually breathing through the mouth instead of the nose
• Open mouth posture — lips apart at rest, tongue low in mouth
• Incorrect swallowing — using facial muscles or tongue push instead of proper swallow mechanics
• Thumb/finger sucking habits — prolonged non-nutritive sucking past age 3-4

How Does It Connect to Speech?

You might wonder why a speech therapist does myofunctional therapy. The connection is direct: the same muscles used for speaking are the muscles we're retraining.

When the tongue doesn't rest in the correct position or the lips don't seal properly, it can cause:

• Lisps and other articulation errors (especially "s" and "z" sounds)
• Unclear speech due to weak oral muscle coordination
• Difficulty producing certain sound combinations
• Compensatory speech patterns

By addressing the underlying muscle patterns, speech often improves naturally — and speech therapy becomes more effective.

How Does It Affect Sleep and Breathing?

This is where many parents are surprised. Chronic mouth breathing and poor tongue posture have been linked to:

• Snoring — even in children, snoring is not normal and can indicate airway issues
• Sleep-disordered breathing — ranging from mild snoring to pediatric sleep apnea
• Daytime fatigue and behavior issues — poor sleep quality can mimic ADHD symptoms
• Dental problems — open bites, crowding, and orthodontic relapse
• Facial development changes — long-term mouth breathing can affect jaw and facial growth

Many parents don't realize that their child's snoring, restless sleep, or "ADHD-like" behavior could be connected to how their mouth and tongue function during the day and night. A myofunctional evaluation can uncover these hidden connections.

What Does Myofunctional Therapy Look Like?

Myofunctional therapy is non-invasive and typically involves:

1. Comprehensive evaluation — assessing tongue posture, swallowing patterns, breathing, lip seal, and oral habits
2. Customized exercise program — targeted exercises to strengthen and retrain specific muscles
3. Habit elimination — addressing thumb sucking, nail biting, or other habits
4. Breathing retraining — transitioning from mouth to nasal breathing
5. Home practice — daily exercises (usually 5-10 minutes) for consistent progress

Sessions typically occur weekly, and most treatment programs run 6-12 months depending on severity. The exercises are simple, painless, and often fun for kids!

Who Can Benefit?

Myofunctional therapy can benefit children and adults of all ages who experience:

• Tongue thrust or incorrect swallowing
• Chronic mouth breathing
• Snoring or sleep issues
• Speech sound errors (especially lisps)
• Prolonged thumb or finger sucking
• Pre- or post-tongue tie release patients
• Orthodontic patients (helps prevent relapse)
• TMJ or jaw pain

Myofunctional Therapy and Tongue Ties

At Speech EZ, we take a therapy-first approach to tongue ties. A restricted frenulum (tongue tie) can certainly cause myofunctional issues, but we believe in trying targeted therapy before jumping to surgical intervention. In many cases, myofunctional exercises can significantly improve function even with a mild restriction.

When a tongue tie release (frenectomy) is truly necessary, we provide essential pre-release therapy to prepare the muscles and post-release exercises to ensure proper healing and function. This combined approach leads to the best outcomes.

Getting Started

If you suspect your child (or you!) might benefit from myofunctional therapy, the first step is a comprehensive evaluation. At Speech EZ, we offer myofunctional evaluations both online across all of Arizona & Wisconsin.

During the evaluation, we'll assess tongue position, swallowing, breathing patterns, and oral habits — then create a personalized treatment plan tailored to your specific needs and goals.
