Sustained and Repeated Mouth Opening Leads to Development of Painful Temporomandibular Disorders Involving Macrophage/Microglia Activation in Mice

Temporomandibular disorder (TMD) is a set of heterogeneous musculoskeletal conditions involving the temporomandibular joint (TMJ) and/or the masticatory muscles. Up to 33% of the population has had at least one symptom of TMD with 5-10% of them requiring treatment. Common symptoms include limited jaw movement, joint sound, and pain in the orofacial area. Once TMD becomes chronic, it can be debilitating with comorbidities that greatly reduce one's overall quality of life. However, the underlying mechanism of TMD is unclear due to the multicausative nature of the disease.

Prevalence of TMD in Sjӧgren Syndrome Patients

Sjӧgren's Syndrome seems to play a role in temporomandibular joint disorders.

Early Molecular Response and Microanatomical Changes in the Masseter Muscle and Mandibular Head After Botulinum Toxin Intervention in Adult Mice

The Botox-injected masseters had greatly increased expression of genes involved in muscle atrophy at the 1 week time point compared to the control side muscles. At the end of the study, 2 weeks after injection, the Botox-injected masseters were about 20% smaller than the control side masseters, and the Botox-side condyles had lost about 40% of relative bone area compared to the control side condyles.

Centralized Pain in TMD: Is It All in the Head?

We are pleased to introduce Sophia Stone, a new contributor to The TMJ Association, whose passion is to separate TMD fact from TMD fiction. Sophia has a background in medicine and research and can draw on her personal experience as a TMD patient.

Courtney's Story

  • May 13, 2015

I'm a 21-year-old mom. I have been suffering from TMJ since I was 13 when I was fitted with braces. Suddenly, I had terrible facial pain which bothered me for years. It improved over time, until last week, when I needed to have some dental work done. Because I had not had severe pain for awhile, I neglected to tell my new dentist about my previous history with TMJ. That day, I had to sit with my mouth wide open for about 45 minutes as the dentist filled six teeth.

The next day I awoke to excruciating pain on the left side of my face. It became so bad that I couldn’t open my mouth at all, so that night I went to the ER at my local hospital. At the hospital, the doctor prescribed an antibiotic, assuming that I had an infection. He also prescribed Percocet for the pain. These medications made me nauseous and they only relieved the pain for about two hours, after a while it returned worse than before. I couldn't move my mouth and I couldn't talk. The only thing that gave me any relief was to put scalding hot wash cloths on my face. Not knowing what else to do, I returned to the ER. This time the doctor assumed that I was a drug seeker, so he gave me a shot of Toradol and told me to see my dentist.

Again, the treatment (the shot) helped me temporarily and I slept through the night, but the morning brought another day of unbearable pain. I tried taking high doses of Motrin and Tylenol even knowing that wasn’t a smart thing to do, but I needed to find some relief.

I did return to my dentist as fast as I could, but at the appointment, he said that he was sorry, he couldn’t help me anymore. He referred me to an oral maxillofacial surgeon. This time I was given a prescription for Valium and even that is not helping – the pain is intense and my ear hurts so much.

One of the worst parts of my story is that I was feeling that nobody I went to believed me when I described my pain and how terrible it was – and it is! Then I found this website [] and learned that I am not alone. It was such a relief to know that there are many others who understand what I’m going through, because they are experiencing it, too. The website has taught me so much about TMD. I am so glad I found it and I wish good luck to everyone suffering from this horrible disease.
