Jaw Dysfunction May Be the Unexpected Cause of Migraines for Millions
New research suggests a surprising link between temporomandibular joint (TMJ) disorders and headaches, possibly explaining a important number of migraine diagnoses. A recent meta-analysis of 74 studies, published by the Medical University of Lublin in Poland and reported by The World, indicates that up to 30% of adults experience cranio-mandibular dysfunction (CMD).
CMD, a dysfunction of the small joint connecting the skull to the lower jaw, can manifest in a variety of ways beyond jaw pain. Symptoms can include dizziness, notably with lateral movements, and a throbbing sensation in the temples – often mimicking migraine headaches. Other potential indicators of CMD include ringing in the ears, a sensation of a lump in the throat, and pain radiating from the face to the back.
The temporomandibular jointS central role in essential functions like chewing, swallowing, speaking, breathing, and even emotional expression contributes to its susceptibility to strain. According to Ralf Bürgers from the Center for Dentistry, oral and Maxillofacial Medicine at the Medical University of Göttingen (Germany), the joint’s “particular anatomical and functional complexity” and constant use explain the high prevalence of CMD. The condition is also frequently linked to bruxism - involuntary jaw clenching often triggered by stress and anxiety.
Diagnosing CMD can be challenging due to the diverse range of symptoms, frequently enough leading patients on a diagnostic journey before receiving specialized dental or interdisciplinary care, as noted by Slate. Women are disproportionately affected, experiencing CMD at roughly twice the rate of men, particularly before menopause.
Treatment options range from behavioral adjustments to medical interventions. Dentists Ingrid Peroz suggests that simply becoming aware of bruxism can often resolve the issue, while Hamdi Kent recommends sleeping on one’s back and avoiding crossing legs.Chewing gum is also best avoided.night splints and physical or speech therapy can further alleviate symptoms and reduce stress on the joint. Surgery remains a final option when other treatments prove ineffective.
