What Is a Myofunctional Evaluation? (And Does My Child Need One?)

If you’ve heard about myofunctional therapy, maybe from a dentist, orthodontist, or online, it’s natural to wonder what it involves and whether your child might benefit. One of the first steps in this process is a myofunctional evaluation, a detailed look at how the muscles of the mouth, face, and airway are functioning together.

This isn’t your average checkup. It goes far beyond brushing habits or cavity checks. Instead, a myofunctional evaluation gives us a window into how your child breathes, swallows, speaks, and rests. Many families in Orange County are surprised by what they learn during this visit, and how much it explains about sleep, attention, and long-term oral health.

A Whole-Body Lens on Oral Function

Myofunctional therapy looks at the muscle patterns that influence how the mouth and face develop. These include tongue posture, lip seal, nasal breathing, and swallowing mechanics. When these patterns are functioning well, they support proper jaw growth, airway health, and even neurological regulation.

When they are not, symptoms may show up as:

• Mouth breathing or noisy breathing during sleep

• Snoring, teeth grinding, or restless sleep

• Speech delays or articulation issues

• Chronic congestion without a clear cause

• Orthodontic relapse or crowding

• Open mouth posture or tongue thrust

• Difficulty chewing or swallowing certain textures

• Forward head posture or slumped sitting

These signs are common, but common does not mean normal. In fact, many children who exhibit these symptoms have underlying muscle and breathing patterns that can be corrected through therapy. A myofunctional evaluation helps identify these patterns early.

What Happens During the Evaluation?

At OC Myo Harmony, our evaluations are designed to be comfortable, educational, and engaging. Whether your child is five or fifteen, we approach the appointment with patience and curiosity. Here’s what we typically assess:

1. Breathing Patterns We look at how your child breathes at rest: through the nose or mouth, with lips closed or open, chest or belly breathing. We may also ask about sleep quality, snoring, or daytime fatigue.

2. Tongue Posture and Mobility We check where the tongue rests when your child is sitting still and breathing quietly. We also evaluate how easily they can lift, move, and control the tongue, which can indicate possible restrictions like tongue ties.

3. Swallowing and Chewing Function We observe how your child chews food and swallows water. This helps us identify whether their tongue and lips are working in sync, or if compensations are happening that could affect development or digestion.

4. Facial and Oral Muscle Tone We examine the function of the lips, cheeks, and jaw to see how the muscles support speech, facial expression, and oral rest posture.

5. Habit History and Developmental Milestones We take time to discuss your child’s birth and feeding history, pacifier or thumb-sucking habits, allergies, and any challenges related to focus, sleep, or behavior.

By the end of the evaluation, you’ll have a much clearer picture of your child’s oral function and whether therapy could be helpful.

Why Early Intervention Matters

Many families wait until there is a major issue, like orthodontic relapse or ongoing behavioral concerns, before seeking support. But early detection is key. A myofunctional evaluation can help prevent future complications and set the stage for better outcomes in orthodontics, speech, sleep, and even academic performance.
