What is Orofacial Myofunctional Therapy?

When a person has problems with an arm or leg they seek physiotherapy to help regain the proper use and function, but what about our mouths?

 Our mouths can be an area that is misunderstood when it comes to muscle function. Many people have an improper use of the oral and facial muscles, which can lead to dental malformations as well as relate to other health issues. Orofacial Myofunctional Therapy is a highly personalized therapy to help target the abnormal muscle use and/or function. We work to improve muscle tone, regain proper resting positions of the tongue and lips and support proper muscle function for eating, chewing and swallowing. When we can get proper muscle use of the oral and facial muscles it can have lasting positive effects!

What can cause an Orofacial Myofunctional Disorder?

  • Long term pacifier use

  • Long term thumb/finger sucking habits

  • Nail biting

  • Lip licking

  • Bottle feeding

  • Restricted airway due to enlarged tonsils, adenoids, deviated septum or chronic allergies

  • Hereditary factors

  • Short lingual frenum (Tongue-Tie)

  • Large tongue (Macroglossia)

  • Routine habit of resting with lips apart

  • Neurologic of developmental abnormalities

Tongue-tie is a complex issue that can affect many people unknowingly. Some tongue-ties aren't as obvious as this particular patient however the impact can be very different from person to person.

Tongue-tie can affect how the tongue is able to do its functions. The tongue has to do many complex functions such as elevating, retracting protruding and lateralizing. What if a small piece of tissue was holding the tongue down like a rope? A patient may experience difficulty with eating, chewing, swallowing, speech and stomach upset (abnormal swallow pattern may contribute to increased ingestion of air).

Where does your tongue sit in your mouth? This may be a weird question but there are typically 3 answers: On the roof of the mouth, in the middle or on the floor of the mouth. The correct position for the tongue is to rest on the roof of the mouth.

Why is tongue position important?

Tongue position is important because the tongue is a huge facilitator for orofacial growth and development. when the tongue rests on the roof of the mouth it helps to stimulate the bone of the maxilla to grow in a more ideal way. When the tongue is not on the roof of the mouth we can start to see a collapse of the dental arch and can notice things such as crowding of the teeth and a non-ideal bite. This can start to affect appearance, create a high vault in the palate (this can affect nasal airway volume), contribute to orthodontic relapse, posture problems and relate to airway issues.

When you see a Certified Orofacial Myologist we do a functional assessment to see if there is dysfunction of the orofacial muscles. If there is a tongue-tie present we look to see if it is contributing to abnormal us of the muscles. If a patient needs a tongue-tie release we work with our patients before and after to optimize the surgical outcomes.


Why be concerned about an Orofacial Myofunctional Disorder?

Orofacial Myofunctional Disorders (OMD) can play a large roll in craniofacial development and can have long-term effects.

OMD’s can also relate to:

*Physical appearance

*The shape of the mouth

*Orthodontic relapse

*Feeding difficulties

*Jaw joint pain

*Dental bite and alignment

*Head and neck posture problems

*Poor sleep patterns

*Poor airway development

*Speech patterns


Myofunctional Therapy Program

Abnormal muscle patterns can be very different from person to person. We do a full assessment of muscle patterns and functions and construct a series of custom treatment plans. We work on proper resting patterns, building muscle strength and work towards normal muscle patterns and function. When we can get proper muscle use of the oral and facial muscles it can have lasting positive effects!

Habit Elimination Program

Did you know?

Thumb/finger sucking can have a negative affect on craniofacial development. Thumb and finger sucking can also negatively impact a child’s airways, speaking and swallowing.

When trying to eliminate a habit such as thumb or finger sucking it can cause a lot of anxiety and stress for the child. It can also be exhausting for parents because they feel like they have tried all options, but now Harmony Myofunctional Therapy is here to help!

We use a proven scientific program that is encouraging and fun to eliminate the problem with no harsh appliances!

Let us help make this a positive change! Call today to book your appointment.

Anterior Open Bite

 Look at the amazing changes in occlusion with this patient! This patient had an Anterior Open Bite. We were able to assess that the tongue was not able to do its function because of a tongue-tie. Since the tongues movement was restricted the patient adapted to a "backwards swallow pattern" where the tongue wants to push forward on the front teeth to accomplish the swallow. This patient was referred for assessment for tongue-tie release (frenectomy). After the tongue had good mobility we were able to work on building strength and develop patterns to regain the normal function of the tongue and surrounding muscles. All patients are different and can have very different dysfunction with the muscle use and patterns. Every patient requires personalized treatment planning and may need the help of multiple practitioners to get the best outcome!
