Most likely diagnosis for unilateral mouth pain with ear and jaw symptoms, plus bruxism?

• A. Migraine
• B. TMJ
• C. Otitis externa
• D. Tension-type headache

Answer: (B)

Unilateral mouth pain with ear and jaw symptoms plus bruxism points to temporomandibular joint dysfunction. The TMJ connects the jaw to the skull, and bruxism—teeth grinding or clenching—places repetitive stress on the joint and surrounding muscles. This often causes jaw pain, tenderness around the temple or preauricular area, and may radiate toward the ear; people may also report jaw clicking or limited opening. The other conditions don’t fit as well: migraines can be unilateral but typically present as a throbbing headache with nausea, photophobia, or aura rather than focused jaw/ear symptoms tied to teeth grinding; otitis externa causes ear canal pain and canal/membrane findings rather than jaw joint pain and bruxism; tension-type headaches are usually bilateral, diffuse, and not linked to jaw clenching or ear-associated jaw pain. So the observed pattern best matches a TMJ disorder.
