Myofunctional Therapy vs. Speech Therapy

Parents often come across both myofunctional therapy and speech therapy while looking into a concern with their child's mouth or speech, and understandably wonder how they differ. The two overlap and sometimes work hand in hand, but they focus on different things. Understanding the distinction helps you figure out which one your child actually needs, or whether both belong in the picture.

What Speech Therapy Focuses On

Speech therapy, delivered by a speech-language pathologist, addresses communication. That covers a wide range: how clearly a child produces sounds, language development, fluency, and sometimes swallowing and feeding. When a child has trouble saying certain sounds or their speech is hard to understand, speech therapy is typically where families turn, and it targets the production of speech and language directly.

Speech-language pathologists work across a broad scope, which is why some also have training in orofacial myofunctional disorders, as recognized by the American Speech-Language-Hearing Association.

What Myofunctional Therapy Focuses On

Myofunctional therapy works on the function and resting posture of the muscles of the face and mouth: how the tongue rests, how a person breathes, how they swallow, and how the lips and jaw behave at rest. Rather than targeting speech sounds directly, it retrains the underlying oral muscle patterns that everything else is built on. Myofunctional Therapy: What It Is and How It Works lays out that scope in detail.

So where speech therapy asks how clearly a child communicates, myofunctional therapy asks how well the tongue, lips, and airway are functioning at rest and in basic actions like breathing and swallowing.

Where They Overlap

The two connect because oral function and speech are related. A tongue that rests low and forward, or a tongue thrust swallowing pattern, can affect both how a child swallows and how they produce certain sounds, particularly a lisp. In cases like that, myofunctional therapy addresses the underlying muscle pattern while speech therapy targets the sound itself, and the two can reinforce each other.

This is why some children benefit from both, sometimes at the same time and sometimes in sequence, with myofunctional work building the foundation that makes speech gains hold.

Which One Does Your Child Need?

A rough way to think about it: if the primary concern is how your child communicates, whether that is unclear sounds, language delays, or fluency, speech therapy is usually the starting point. If the concern is how the mouth functions, an open-mouth posture, chronic mouth breathing, a forward tongue rest, or a swallowing pattern affecting the teeth, myofunctional therapy is likely the better fit. Proper Tongue Posture: What It Is and Why It Matters can help you spot the functional signs.

The honest answer is that they are not either-or, and the clearest way to know is an evaluation that looks at what is actually going on. If you are unsure which direction fits your child, a short discovery call is a good way to talk it through and point you toward the right kind of support.
