Most people do not think about tongue posture while eating, lip position while resting, or how breathing patterns affect everyday activities. These functions usually happen automatically. But when the muscles and movement patterns of the mouth and face do not work together efficiently, the effects can appear in surprisingly ordinary moments—speaking in a conversation, chewing a meal, swallowing, breathing comfortably, or maintaining a natural oral posture.

These patterns may be associated with orofacial myofunctional disorders (OMDs). OMDs can occur across the lifespan and may involve the tongue, lips, jaw, and other orofacial muscles during resting posture, breathing, swallowing, and speech.

For appropriate candidates, Orofacial Myofunctional Therapy can be part of a broader treatment plan designed around functional needs rather than isolated exercises.

When Does an Oral Pattern Become a Functional Problem?

An unusual tongue position or mouth-open posture does not automatically mean someone has an OMD. The key question is whether an atypical pattern is affecting function.

Consider someone who regularly breathes through their mouth, has difficulty maintaining a comfortable tongue-resting position, or uses a forward tongue movement when swallowing. Another person may have chewing difficulties, persistent drooling, speech sound concerns, or jaw-related symptoms.

These signs can have different causes. Airway obstruction, allergies, structural differences, learned habits, and other factors may contribute to OMDs, which is why professional assessment matters.

What Does the Tongue Have to Do With Everyday Function?

The tongue does much more than speech.

It helps position food during chewing, supports swallowing, participates in speech production, and maintains a resting relationship with the teeth and palate.

When tongue posture or movement is atypical, it may affect several functions at once. For example, a tongue-thrust swallowing pattern may affect swallowing and can coexist with certain speech sound difficulties.

This does not mean that every speech problem is caused by tongue posture. Instead, an evaluation helps determine whether an orofacial movement pattern is actually contributing to a person’s specific difficulty.

What Happens During an OMD Evaluation?

A meaningful OMD treatment plan should begin with assessment—not a predetermined list of exercises.

A trained speech-language pathologist may consider:

• Resting position of the tongue, lips, and jaw
• Oral movement and coordination
• Breathing patterns
• Chewing and swallowing
• Speech production and articulatory placement
• Oral habits
• Functional impact on daily activities

The clinician may also review medical, dental, orthodontic, or other relevant history.

According to the American Speech-Language-Hearing Association (ASHA), assessment of OMDs considers how oral and facial movement patterns affect functions such as breathing, talking, eating, and swallowing.

That functional perspective is important: the objective isn’t simply to make a movement look different. It is to address a pattern when it is interfering with meaningful activities.

What Can OMD Therapy Actually Change?

OMD therapy is individualized, and the goals depend on the person’s assessment.

Intervention may address awareness and control of tongue, lip, and facial movements, resting posture, swallowing patterns, and functional oral coordination. When an OMD is associated with speech production difficulties, myofunctional intervention may be incorporated with appropriate speech treatment rather than automatically replacing it.

For example, meaningful progress might involve:

Eating: Developing more coordinated chewing or swallowing patterns.

Speaking: Supporting appropriate articulatory placement when an orofacial pattern contributes to a speech concern.

Resting posture: Establishing more functional tongue and lip positioning.

Daily awareness: Recognizing habits such as persistent open-mouth posture and working toward healthier functional patterns when appropriate.

The measure of success is what happens outside the therapy session.

Is OMT the Same as Speech Therapy?

Not exactly. Speech therapy addresses communication concerns such as speech sound production, language, fluency, voice, and other communication needs. Orofacial myofunctional therapy focuses on functional movement patterns involving the oral and facial structures.

There can be overlap, particularly when an OMD and speech difficulty occur together. ASHA notes that clinicians should distinguish OMD-related speech concerns from other speech sound disorders and may combine OMT with articulation intervention when clinically appropriate.

This distinction helps prevent a one-size-fits-all approach.

Why Can Collaboration Matter?

Orofacial concerns sometimes involve more than speech-language pathology.

For example, persistent mouth breathing may have an underlying airway or nasal issue that requires medical evaluation. Dental alignment and temporomandibular concerns may require assessment by dental or orthodontic professionals.

ASHA describes OMD care as an interprofessional area of practice, with speech-language pathologists collaborating with medical, dental, and orthodontic professionals when appropriate. It also notes that sleep-disordered breathing requires medical evaluation and diagnosis.

That collaborative approach can be especially valuable when several factors contribute to the same functional problem.

Who May Benefit From Orofacial Myofunctional Therapy?

OMD concerns can occur in children, teenagers, and adults. The appropriate intervention depends on the individual’s symptoms, functional abilities, developmental level, and ability to participate in therapy.

Potential reasons for an evaluation may include persistent tongue-thrust swallowing, unusual oral resting posture, mouth breathing, chewing or swallowing concerns, certain speech sound difficulties, or other suspected orofacial movement patterns.

Importantly, OMT is not a universal treatment for every speech, breathing, or swallowing problem. A qualified evaluation should determine whether it is appropriate.

What Does Meaningful Progress Look Like?

The most useful question isn’t, “How many exercises did I complete?”

It is: “Is this changing something I actually do every day?”

Progress might mean eating more comfortably, developing a more functional swallowing pattern, improving oral awareness, or supporting more accurate speech production when an OMD is contributing to the difficulty.

At Total Speech Therapy, the focus is on connecting therapy goals to real-world function rather than treating isolated movements without context.

Total Speech Therapy provides individualized Orofacial Myofunctional Therapy in Baltimore and Houston. Our approach considers the relationship between oral function, speech, swallowing, and communication while recognizing when collaboration with other healthcare professionals may be appropriate.

If you or a family member has concerns about tongue posture, mouth breathing, swallowing, chewing, speech production, or other orofacial patterns, a professional evaluation can help clarify whether an OMD may be contributing to the problem.

Better oral function can have practical implications for everyday communication, eating, and participation. The first step is understanding what is happening and why.
