Welcome to Oral Function Specialties

We perform an extensive evaluation for orofacial myofunctional disorders (OMD’s). Some of the main contributors to OMD’s can be tongue tie, oral habits, such as thumb sucking and airway issues including large tonsils. From the information we gather, we provide our patients an individualized program tailored to their needs.

Our Services

Whole-body care for oral function, growth, and nervous system health.
At Oral Function Specialties, we offer a unique blend of therapies that support the body’s natural ability to grow, feed, breathe, and heal—starting at birth and continuing through adulthood. Each service below has its own section so you can explore what fits your needs.

Myofunctional Therapy

Training the muscles that support healthy breathing, sleep, and development

From tongue posture to swallowing and sleep-disordered breathing, we guide habits that support lifelong health.

Lactation Support (IBCLC)

For babies who struggle to latch, transfer milk, or feed comfortably.

IBCLC-informed care that looks beyond weight gain and into the root of feeding challenges—using a gentle, whole-body lens.

Craniosacral Fascial Therapy

Gentle touch for deep tension release and nervous system support.

Used with newborns through adults to support feeding, sleep, digestion, trauma recovery, and postural balance.

Retained Reflex Integration

Developmental support for children and adults with unresolved reflexes.

Helpful for focus, coordination, sensory regulation, and lingering motor challenges.

Do you suffer from any of these?

People with myofunctional habits can identify many symptoms, but are often unable to tie it all together. An orofacial myologist will help identify the concerns and educate the patient on why treatment is necessary. The symptoms, or concerns, of the patient include but are not limited to the following:

  • Mouth Breathing

  • Orthodontic Relapse

  • Chronic Tension

  • Mood Disorders

  • Jaw Pain

  • Noxious Oral Habits
  • Tongue Thrust

  • Snoring

  • Chronic Headaches

  • Grinding

  • Swallowing Difficulty

  • Poor Posture

  • Sleep Apnea

  • Tongue-Tie

  • Speech Problems

  • Digestive Issues

What is OMD?

These can be unconscious behaviors that cause muscles to function in the incorrect way. They can also include damaging habits that cause the mouth to develop improperly. The muscles affected can include the tongue, lips, jaw and face. Often times, many muscles are involved due to a ripple effect. If one muscle is working incorrectly, this can cause other muscles to compensate and work inaccurately as well.

Symptoms

Symptoms of orofacial disorders can be very obvious or can happen over a period of time and be unclear. Signs and symptoms of OMD can include open mouth breathing, lisping during speech and abnormalities with teeth alignment. These symptoms can be a sign of a disorder that can be helped with our orofacial myofunctional program.

Program

Our Program is appropriate for children, teens and adults. Program goals are individualized and are meant to create new healthy oral habits. The benefit of healthy habits can include nasal breathing, a proper swallow pattern, favorable resting tongue position and preserving orthodontic results from this program.

Icon

“Oral resting position means where the muscles of the mouth are at rest. When the tongue cannot rest inside the roof of the mouth and the lips do not stay closed, teeth become crowded, faces grow to be longer and the airway can be compromised.”
