You may have been referred for myofunctional therapy because your child has a tongue thrust, a persistent lisp, or difficulty keeping their mouth closed at rest.
Perhaps your dentist noticed an unusual swallowing pattern. Or you’re an adult concerned about mouth breathing, oral posture, chewing, or another persistent functional problem.
You may be wondering what happens at the first appointment.
Will someone examine your tongue? Will you be given exercises? How does the clinician know which problems need treatment—and which symptoms may have another cause?
A comprehensive orofacial myofunctional evaluation is much more than a tongue examination. It investigates how the lips, tongue, jaw, and related structures function at rest and during everyday activities, while considering medical history, breathing, speech, chewing, swallowing, and other relevant concerns.
At BreatheWorks, our clinical philosophy is to ask the right questions, listen first, and use the findings to guide the next steps.
That means an evaluation should answer more than whether someone has an unusual tongue posture. It should help determine why a pattern may be occurring, whether it affects daily function, what additional assessment may be needed, and whether therapy is appropriate.
What Is an Orofacial Myofunctional Evaluation?
An orofacial myofunctional evaluation is a clinical assessment of the resting postures and movement patterns of the muscles and structures of the face and mouth.
It may be recommended when someone experiences:
- Persistent mouth-open resting posture
- Low, forward, or interdental tongue posture
- Tongue thrust during swallowing
- Certain speech sound distortions, including some lisps
- Difficulty maintaining comfortable lip closure
- Chewing or oral food-management difficulties
- Persistent oral habits that may affect function
- Functional concerns identified by a dentist or orthodontist
An evaluation may also identify symptoms requiring medical attention, including persistent nasal obstruction or possible sleep-disordered breathing.
However, an orofacial myofunctional evaluation does not replace a medical airway examination, diagnostic sleep testing, or dental and orthodontic assessment.
The goal is to understand the patient’s specific presentation and identify an appropriate course of care.
Step 1: We Begin by Listening to Your Story
A comprehensive evaluation starts before any exercise or movement test.
The clinician needs to understand what brought you to the appointment.
A parent may say, “My child has been in speech therapy, but the lisp hasn’t improved.”
An adult may explain, “My dentist says I push my tongue against my teeth.”
Another patient may report, “I breathe through my mouth all day, but I don’t know why.”
These concerns may sound similar to others the clinic has encountered, but each patient has a different history.
The clinician begins by asking questions and listening carefully to the answers.
Understanding the primary concern
Questions may include:
- What concerns you most?
- When did you first notice the problem?
- Is it constant, or does it occur during specific activities?
- Has it changed over time?
- Does it interfere with speaking, eating, swallowing, or daily comfort?
- What have other healthcare professionals told you?
- What have you tried so far?
- What would meaningful improvement look like to you?
For children, parents and caregivers provide important observations about development, habits, eating, speech, and sleep.
For adults, the clinician may explore work demands, daily routines, previous treatments, and how symptoms affect quality of life.
Reviewing relevant medical and developmental history
Depending on the patient, the clinician may also ask about:
Breathing and airway history: Chronic congestion, allergies, nasal obstruction, snoring, sleep-related breathing concerns, or prior ENT evaluation.
Dental and orthodontic history: Bite concerns, braces, palatal expansion, retainers, or dental recommendations.
Speech and language history: Persistent sound errors, prior speech therapy, or changes in communication.
Feeding and swallowing history: Chewing difficulties, food avoidance, tongue thrust, swallowing concerns, or prior feeding therapy.
Oral habits: Thumb or finger sucking, pacifier use, nail biting, or other persistent behaviors.
Medical and surgical history: Relevant diagnoses, medications, injuries, prior procedures, or treatments.
Developmental history: Age-appropriate milestones, growth, and functional development when relevant.
These questions are not an administrative formality.
They help the clinician decide what to examine, what information may be missing, and whether another healthcare professional should be involved.
The evaluation is guided by the patient’s history—not by a predetermined exercise program.
Step 2: We Observe Natural Oral Resting Posture
Next, the clinician considers how the tongue, lips, and jaw are positioned when the patient is not deliberately performing a task.
This is important because resting posture may differ from what someone can demonstrate when asked to place their tongue in a particular position.
For example, a child may be able to close their lips on command but normally sit with their mouth open.
An adult may be able to lift their tongue toward the palate during a test but habitually rest it against the lower teeth.
Neither observation, by itself, establishes a disorder.
The clinician considers the findings in the context of the patient’s anatomy, development, breathing, and functional concerns.
Tongue resting posture
The clinician may observe whether the tongue habitually rests low, forward, between the teeth, or in another position.
Atypical resting posture can be a feature of an orofacial myofunctional disorder.
However, normal tongue positions vary, and the clinician should not assume that everyone must maintain one exact tongue-tip location.
Lip resting posture
The clinician may observe whether the lips naturally rest together or apart.
If the patient has difficulty maintaining comfortable lip closure, the evaluation considers possible contributing factors.
These may include breathing difficulty, anatomical relationships, or functional movement patterns.
The goal is not to force the mouth closed without understanding why it remains open.
Jaw and dental relationships
The clinician may observe the jaw at rest and note relevant dental or orthodontic findings.
An SLP may document observations that influence oral function, but diagnosing malocclusion and prescribing orthodontic treatment are responsibilities of appropriately qualified dental professionals.
Step 3: We Examine the Orofacial Structures and How They Move
A comprehensive orofacial examination considers more than whether the tongue appears strong or flexible.
The clinician looks at relevant structures and how they work together.
Depending on the patient’s age, symptoms, and clinical needs, this may include examination of:
Tongue movement and coordination
The clinician may ask the patient to perform selected tongue movements.
The purpose is to observe movement, coordination, range, and whether other structures compensate.
For example, does the jaw move excessively when the patient attempts a tongue movement? Can the tongue perform a requested movement without unnecessary lip or jaw activity?
These observations can help identify patterns that warrant further functional investigation.
They should not be interpreted as proof that a particular muscle is weak without appropriate supporting evidence.
Lip and cheek function
The clinician may observe lip movement, closure, and coordination during relevant tasks.
Cheek function may also be considered when there are concerns about food management, swallowing, or oral control.
Jaw movement and stability
The clinician may observe jaw movement during selected oral activities.
If the patient reports pain, locking, or other symptoms suggesting a temporomandibular disorder, dental or medical assessment may be necessary.
Oral anatomy
Relevant structural observations may include the tongue, palate, dentition, and lingual frenulum.
For example, the clinician may identify a feature that raises questions about restricted tongue movement.
However, the appearance of a tongue-tie alone does not establish functional impairment or the need for surgery.
Any decision about a surgical procedure requires appropriate evaluation by a qualified medical or dental professional.
A comprehensive assessment considers both structure and function. Neither should be interpreted in isolation.
Step 4: We Investigate Breathing Patterns and Airway-Related Concerns
Breathing is an important part of the history for many patients seeking myofunctional evaluation.
Some people habitually rest with their mouths open because breathing through the nose is uncomfortable or difficult.
Others have persistent oral-posture patterns even after a contributing medical issue has been addressed.
The clinician may observe breathing behavior while the patient is awake and ask about symptoms such as:
- Persistent nasal congestion
- Difficulty breathing comfortably through the nose
- Frequent mouth breathing
- Snoring
- Restless sleep
- Gasping or witnessed breathing pauses
- Prior diagnoses or treatment for sleep-disordered breathing
These observations help identify concerns that may need medical assessment.
Why medical airway evaluation matters
An SLP cannot determine from tongue posture alone whether a patient has enlarged adenoids, a deviated septum, nasal polyps, or obstructive sleep apnea.
A patient who cannot breathe comfortably through the nose may not be an appropriate candidate for closed-mouth resting-posture training until the underlying issue has been evaluated.
If the history suggests nasal obstruction or sleep-disordered breathing, the clinician may recommend assessment by an ENT, pediatrician, sleep specialist, or another qualified medical professional.
Myofunctional therapy cannot remove a structural airway obstruction.
Recognizing when medical evaluation is needed is part of comprehensive care.
Step 5: We Assess Swallowing Patterns When Indicated
The tongue plays an important role in managing saliva, liquids, and food.
Some patients are referred because a dentist or orthodontist has observed a possible tongue thrust.
Others report difficulty swallowing comfortably or managing certain foods.
When clinically indicated, an appropriately trained SLP may observe relevant swallowing behaviors.
What is the clinician looking for?
The assessment may consider:
- Tongue movement during swallowing
- Lip and jaw participation
- Compensatory facial movements
- Coordination of relevant oral structures
- Functional concerns reported by the patient
For example, a person may demonstrate forward tongue movement during a swallow.
The clinician considers whether the pattern is developmentally appropriate, whether it is consistent, and whether it has meaningful functional implications.
What if a swallowing problem is more complex?
A screening observation is not a substitute for a comprehensive dysphagia evaluation.
If the patient reports coughing, choking, food sticking, painful swallowing, or other symptoms suggesting a swallowing disorder, additional assessment or medical referral may be needed.
In selected cases, an appropriately qualified clinician may recommend instrumental swallowing assessment.
The purpose is to distinguish an orofacial movement pattern from a swallowing disorder that requires a different diagnostic or treatment approach.
Step 6: We Evaluate Chewing and Food Management When Relevant
Chewing requires coordinated activity of the tongue, jaw, lips, and cheeks.
For patients with feeding or oral food-management concerns, a clinician may investigate how food is handled and moved during eating.
Questions may include:
- Does the patient avoid certain textures?
- Is chewing unusually slow or difficult?
- Does food frequently collect in the cheeks?
- Is food moved effectively from one side of the mouth to the other?
- Are there compensatory jaw, tongue, or lip movements?
- Is there discomfort or fatigue while eating?
When indicated, functional observations may be conducted with appropriate foods and clinical precautions.
Not every patient requires food trials during an OMD evaluation.
If symptoms suggest a broader pediatric feeding disorder or dysphagia, a separate comprehensive evaluation may be appropriate.
Step 7: We Screen Speech Production and Communication When Indicated
This is one of the important advantages of an evaluation performed by an SLP with specialized orofacial myofunctional training.
The same structures involved in oral resting posture and swallowing are also involved in speech.
However, their movement patterns differ depending on the task.
A child with a lisp may also demonstrate tongue thrust during swallowing.
That does not automatically mean the swallowing pattern caused the speech error.
The clinician needs to examine speech production directly.
What may be assessed?
Depending on the patient’s history, an SLP may evaluate:
Speech sound placement: How the tongue, lips, and jaw move during particular speech sounds.
Speech clarity: Whether sound distortions affect intelligibility or communication.
Consistency: Whether the error occurs in isolated sounds, words, conversation, or other contexts.
Movement patterns: Whether compensatory jaw or tongue movements occur during speech.
Response to cues: Whether the patient can modify sound production when given appropriate instruction.
A screening may indicate that a full articulation or speech sound evaluation is needed.
The purpose is to determine which difficulties are present and whether they require direct speech treatment, myofunctional intervention, or separate approaches.
Step 8: We Use Measurements and Clinical Assessments to Clarify the Findings
A comprehensive evaluation is not simply a series of observations followed by a recommendation.
When appropriate, clinicians use structured assessments, documented measurements, patient-reported information, and dynamic testing to answer specific clinical questions.
For example, an assessment may help establish:
- The patient’s current functional abilities
- Whether a pattern occurs consistently
- How a particular movement is coordinated
- Whether the patient can modify a movement with instruction
- Which functional limitations matter most
- What baseline information can be used to monitor progress
The specific tools should be selected according to the patient’s presentation and the clinical question being investigated.
Not every test is appropriate for every patient.
Why interpretation matters more than collecting numbers
An isolated measurement rarely tells the whole story.
A patient may perform well during a structured task but have difficulty applying the same skill in everyday activities.
Another patient may demonstrate an unusual movement that does not create a meaningful functional limitation.
The clinician must interpret findings alongside the history, anatomy, development, medical information, and patient goals.
The purpose of measurement is to improve clinical decisions—not to make an evaluation appear complicated.
Step 9: We Determine Whether Other Specialists Should Be Involved
A comprehensive myofunctional evaluation should identify both what the clinician can address and what requires additional expertise.
Depending on the findings, the care team may include:
- An ENT for nasal or upper-airway concerns
- A pediatrician or primary care clinician for medical evaluation
- A sleep specialist for suspected sleep-disordered breathing
- A dentist or orthodontist for dental alignment and related concerns
- An oral surgeon for selected structural concerns
- A feeding or swallowing specialist when additional assessment is required
- Other appropriately qualified healthcare professionals
The goal is not to refer every patient to every specialist.
It is to identify which additional perspectives are necessary to understand and address the patient’s concerns.
Sometimes treatment can begin while coordinated care continues.
In other situations, medical or dental evaluation should occur before functional therapy.
Step 10: We Explain the Findings and Develop an Individualized Plan
At the end of the evaluation process, the clinician brings the information together.
A meaningful clinical summary should answer:
- What concerns brought the patient to BreatheWorks?
- What did the history reveal?
- Which functions were assessed?
- What strengths and difficulties were identified?
- Which findings are clinically significant?
- How do they affect daily activities?
- Are there concerns requiring further medical, dental, or SLP evaluation?
- Is skilled myofunctional therapy appropriate?
- What specific goals should treatment address?
- How will progress be monitored?
The answer is not always “start myofunctional exercises.”
For some patients, the recommendation may be medical evaluation, orthodontic coordination, direct speech treatment, feeding or swallowing assessment, monitoring, or education.
For others, individualized orofacial myofunctional therapy may be appropriate.
What might a treatment plan include?
Depending on the evaluation, therapy may target:
- Awareness and modification of relevant oral resting-posture patterns
- Functional tongue and lip coordination
- Selected swallowing patterns
- Carryover of appropriate skills into daily routines
- Integration with direct speech treatment when indicated
- Reassessment of specific functional goals
The treatment plan should reflect the patient’s age, readiness, medical status, abilities, and priorities.
It should also explain how the clinician will determine whether treatment is helping.
Why Is an SLP-Led Myofunctional Evaluation Different?
Speech-language pathologists are educated to evaluate speech and communication, and, within their professional scope and competencies, feeding and swallowing function.
These areas involve many of the same anatomical structures considered in an orofacial myofunctional evaluation.
An SLP with specialized OMD training can investigate the relationships among oral resting posture, speech production, chewing, and swallowing without assuming that every symptom has the same cause.
Consider three examples.
Example 1: A child referred for a lisp
The child may have a speech sound disorder, an atypical tongue resting pattern, both, or another contributing issue.
An SLP can evaluate actual speech production, examine relevant oral function, and determine whether direct articulation therapy, myofunctional intervention, or another approach is indicated.
Example 2: An adult referred for tongue thrust
The patient may demonstrate a persistent swallowing pattern alongside dental or orthodontic concerns.
The evaluation considers the functional pattern, its impact, and whether coordination with the dental team is appropriate.
Example 3: A child referred for mouth breathing
The child may have nasal obstruction, a functional oral resting-posture concern, or both.
The clinician must consider medical airway issues before assuming the child needs exercises.
These examples illustrate why clinical reasoning matters.
A visible symptom may be the starting point, but it should not automatically determine the treatment.
Not all SLPs have specialized OMD training. Other appropriately qualified professionals also contribute to assessment and treatment.
The most important distinction is whether the clinician has the relevant expertise, evaluates the patient’s actual functional needs, and coordinates care when appropriate.
How Long Does a Myofunctional Evaluation Take?
The appointment length depends on the patient’s age, clinical complexity, and the assessments required.
Some patients have one primary functional concern. Others have histories involving speech, feeding, dental treatment, breathing, and multiple healthcare providers.
In more complex cases, additional testing or a separate specialty evaluation may be recommended.
BreatheWorks can provide current scheduling details when you arrange an appointment.
A thorough evaluation should be guided by clinical need rather than a promise that every patient will complete the same tests within the same amount of time.
Do You Receive Exercises at Your First Appointment?
Not necessarily.
Some patients may receive education, initial strategies, or appropriate home recommendations during the first visit.
Others may need further assessment or medical evaluation before a therapy program is appropriate.
The purpose of the first appointment is to understand the problem and determine the next steps.
Exercises should follow the clinical findings, not precede them.
What Should You Bring to Your Evaluation?
Helpful information may include:
- A list of relevant medical diagnoses and medications
- Previous speech-language, feeding, or swallowing reports
- Dental or orthodontic recommendations
- Relevant ENT or sleep-study findings
- A summary of symptoms and when they occur
- Questions about the patient’s functional concerns and goals
If you have been asked to complete intake forms, providing accurate information helps the clinician prepare.
For a child, observations from parents and caregivers can be especially valuable.
If you are unsure whether a particular record is needed, ask the clinic before the appointment.
Frequently Asked Questions
What is included in a myofunctional evaluation?
A comprehensive evaluation typically includes a detailed history, assessment of relevant oral structures and resting posture, functional observations, and investigation of speech, swallowing, chewing, or breathing-related concerns when indicated. The clinician interprets the findings and recommends treatment or referral as appropriate.
Is a myofunctional evaluation painful?
Most components involve conversation, observation, and noninvasive oral movement tasks. Any additional examination should be explained and adapted to the patient’s comfort and clinical needs.
Can an SLP diagnose an orofacial myofunctional disorder?
An appropriately trained SLP can assess and diagnose OMDs within their professional scope and applicable requirements. Medical, dental, and sleep-related conditions require diagnosis by the appropriate professionals.
Does every patient need a sleep study?
No. Sleep testing is not a routine requirement for every OMD evaluation. It may be recommended by a qualified medical professional when symptoms suggest sleep-disordered breathing.
Does a tongue-tie automatically mean I need surgery?
No. The appearance of a restrictive frenulum does not automatically establish the need for a procedure. Decisions should consider functional findings and appropriate medical or dental assessment.
Can myofunctional therapy replace speech therapy?
No. Myofunctional therapy and speech-language treatment address different, sometimes overlapping clinical goals. An SLP can determine whether direct speech intervention, orofacial functional therapy, or both are appropriate.
Does everyone who mouth breathes need myofunctional therapy?
No. Mouth breathing can have medical, anatomical, or functional contributors. Appropriate evaluation is needed before selecting treatment.
What happens if the evaluation identifies another problem?
The clinician may recommend additional assessment, refer to another healthcare professional, or coordinate treatment with the existing care team.
Can adults benefit from an evaluation?
Yes. Orofacial myofunctional disorders can occur across the lifespan. Whether therapy is appropriate depends on the individual’s functional findings, medical status, and goals.
Better Questions Lead to Better Treatment Decisions
A comprehensive myofunctional evaluation should not begin with the assumption that every patient needs the same exercises.
It should begin with curiosity, careful listening, and a thorough understanding of the person’s symptoms and daily life.
At BreatheWorks, our approach is to investigate relevant functions, interpret findings in context, recognize when other specialists are needed, and develop individualized recommendations.
The goal is not simply to identify an unusual pattern. It is to understand what that pattern means for the patient—and what, if anything, should be done about it.
If you or your child has concerns involving tongue posture, mouth breathing, tongue thrust, speech, chewing, or swallowing, contact BreatheWorks to discuss whether a comprehensive orofacial myofunctional evaluation may be appropriate.
