The primary cause of an orofacial myofunctional disorder (OMD)

January 2022

The primary cause of an orofacial myofunctional disorder (OMD) is an open mouth posture or mouth breathing due to nasal structural obstructions and allergies.

It is often difficult to identify a single cause for an orofacial myofunctional disorder. Most disorders involve a combination of factors that may include:

  • Nasal airway interference from enlarge tonsils or adenoids, allergies or anatomical deviations involving the nasal cavity or pharynx.
  • Improper oral habits such as thumb or finger sucking, cheek or nail biting, teeth clenching or grinding.
  • Structural or physiological abnormalities such as short lingual frenum (tongue-tie)
  • Hereditary predisposition to any of the above factors.

Nasal airway interference – mainly Allergies – are the primary cause of OMDs.

Dr. Honor Franklin is an IAOM Certified Orofacial Myofunctional Therapist at Honor Franklin Myofunctional & Speech Clinic and has an Allergist and ENT on her team who are the best at diagnosing and treating the causes of mouth breathing. Call today for their name and numbers.

How Orofacial Myofunctional Therapy can continue to improve patient’s occlusion 22 years following OMT!

September 2017

It always make my day when patients come back to see me!

It’s exciting to see how Orofacial Myofunctional Therapy (OMT) can help a patient’s dental occlusion continue to improve years later after graduating from OMT…in this case, 22 years later!!!

This male patient was referred to me by his pediatric dentist, Dr. Mark Kogut of My Kids DDS  when he was 15 years old.

An Orofacial Myofunctional evaluation revealed an Orofacial Myofunctional Disorder (OMD) characterized by an incorrect oral rest posture of his tongue and lips resulting in a dental openbite and overjet.

Since the primary cause of an OMD is nasal airway problems, he was referred to the Allergist and ENT on my team who understand Orofacial Myofunctional Disorders (OMDs). The Allergist’s evaluation revealed Seasonal Allergic Rhinitis and the ENT evaluation revealed a nasal structural obstruction resulting in a tonsillectomy and partial inferior turbinate reduction. Once he healed from the surgeries and once the Allergist taught him how to control his allergies, Orofacial Myofunctional Therapy (OMT) was initiated at this clinic.

The first set of photos were taken when he was 15 years old.

The third set of photos were taken when he was seen 3 years after completing OMT.

Brad Schweig After TX


The fourth set of photos were taken 22 years after OMT.  Notice how his dental occlusion has continued to improve with no additional orthodontic treatment.

NOTE: OMT does not take the place of orthodontic treatment.

You Will Not Believe What This Patient’s Dentist Required Him to Wear Following Orthdontics and Jaw Surgery!

August 2017

I love it when my patients come back to see me!

This patient was referred to me in 1989, when he was 34 years old by his maxillofacial surgeon after having undergone orthodontic treatment FIVE times! ( In 1967-1968 and again 1976-1977 in Philadelphia, 1978-1980 in California, 1981-1984 in Dallas, Texas and 1988-1989 in Philadelphia).

When he presented to me for an Orofacial Myofunctional Evaluation in 1989 at age 34 years old, he was wearing upper and lower retainers during the day and you will not believe what he was instructed to wear at night to prevent his orthodontic – surgical treatment from relapsing – this horrific “tongue thrust” appliance!!

It is well known that nasal airway problems are a the primary cause of an orofacial myofunctional disorder (OMD), so recognizing the signs of sinusitis is important.

Sinusitis in Texas (and the rest of the United States) is a common problem. The Centers for Disease Control estimates that more than 29 million Americans suffer from chronic sinusitis.

Remarkably, that’s nearly 13 percent of the entire population.

We hear you asking, “What is sinusitis?”


Is Orofacial Myofunctional Therapy (OMT) or Tongue Thrust Therapy Just for Kids?

May 2017

Happy Patient of Dr. Honor Franklin

My patient, Gerald, age 52 years old, sent me this selfie photo when his orthodontic braces were removed. Look at that happy smile!

“Is Orofacial Myofunctional Therapy (OMT) or Tongue Thrust Therapy just for Kids?”

I get asked this question everyday and the answer is, “Absolutely Not!”

The oldest patient I have seen for orofacial myofunctional therapy (OMT) has been 76 years of age!

OMT was initiated on this patient in 2013, when he was 49 years old and he graduated from OMT when he was 52 years old.

Gerald was initially referred to me by his orthodontist, Dr. Cliff Alexander of Preston Hollow Orthodontics in 2007 when he was 43 years old. He was diagnosed as being an orthodontic surgical case and Gerald decided to postpone treatment because he did not want surgery.
