JOMS Study: Jaw Pain Condition May Signal Higher Risk for Sleep Apnea, Research Finds

People diagnosed with a temporomandibular disorder – commonly known as TMD – were significantly more likely to screen at high risk for obstructive sleep apnea, according to new research.

ROSEMONT, Ill., Sept. 1, 2026 /PRNewswire/ -- Patients diagnosed with a temporomandibular disorder (TMD) are at increased risk for obstructive sleep apnea (OSA) compared to people without the disorder, according to a study published in the Journal of Oral and Maxillofacial Surgery (JOMS), the peer-reviewed official journal of the American Association of Oral and Maxillofacial Surgeons (AAOMS).

TMD is a group of conditions affecting the jaw joint and the muscles surrounding the joint – including joint pain (arthralgia) and muscle pain (myalgia) – that can cause difficulty opening the mouth, clicking or popping sounds in the jaw and persistent facial pain. Obstructive sleep apnea is a sleep disorder in which the airway repeatedly collapses during sleep, causing a person to briefly stop breathing. Both conditions are common, but clinicians do not always screen for sleep apnea when treating jaw pain – or vice versa.

Researchers recruited 100 patients – half diagnosed with a TMD, half without – matched by age and sex, and used a standard sleep apnea screening tool to compare their risk levels. To isolate the relationship between the two conditions, patients with a history of jaw trauma, teeth grinding/clenching and certain craniofacial conditions were not included in the study. The findings suggest that jaw pain and sleep apnea may be more closely connected than previously recognized, and that patients being treated for one condition should be evaluated for the other.

In this study, patients with TMD scored nearly double on a standard sleep apnea risk questionnaire compared to matched controls. More than 60 percent of TMD patients scored in the intermediate or high-risk range for sleep apnea, compared to 24 percent of those without TMD. That association held even after researchers accounted for factors known to influence sleep apnea risk, such as age, sex and body mass index, suggesting the connection between the two conditions is meaningful on its own.

The study also identified specific symptoms that were strongly associated with elevated sleep apnea risk among TMD patients: snoring, persistent fatigue and episodes of observed stopped breathing during sleep. These are all signs that patients and their bed partners may already be noticing. Patients reporting any combination of these symptoms alongside jaw pain should bring them to the attention of their care team.

Researchers believe the two conditions may reinforce each other through a cycle of pain and disrupted sleep. One leading theory is that sleep apnea triggers brief, forceful jaw clenching episodes during the night as the body struggles to reopen the airway. Over time, that repeated muscle strain can damage the jaw joint and surrounding tissue, contributing to or worsening TMD. Sleep fragmentation also may lower the body's pain threshold, making existing jaw pain feel more intense.

"These findings underscore the importance of integrating routine OSA screening into the standard evaluation of TMD patients and advocate for greater interdisciplinary collaboration between dental and sleep medicine specialists to optimize patient care," the authors said.

Patient Takeaway
Anyone being treated for chronic jaw pain, jaw joint clicking or TMD-related facial pain should ask their oral and maxillofacial surgeon whether they also should be screened for sleep apnea. Conversely, patients already diagnosed with sleep apnea may benefit from a jaw evaluation. An oral and maxillofacial surgeon is uniquely trained to assess and treat conditions involving the jaw, mouth and face. To find a qualified surgeon, visit MyOMS.org/Find-a-Surgeon.
