Facial Pain’s Most Commonly Missed Diagnosis!

Dear Colleague,

One of the most frequently misdiagnosed causes of facial and dental pain is temporalis tendonitis—a condition that mimics toothache so convincingly that patients often undergo unnecessary root canals or extractions, despite no visible dental pathology. The pain is typically felt in the upper posterior molars, but when the tendon is especially inflamed—often from nighttime clenching (classic TMD)—the lower molars can also ache. Because the pain can be intense and persistent, both patients and doctors may feel pressured to act, even when imaging and exams show nothing wrong with the teeth.

Beyond tooth pain, temporalis tendonitis is also frequently misdiagnosed as sinus problems or mistaken for joint specific TMJ-related pain, which often leads to unnecessary imaging, consultations, and procedures. What makes this diagnosis so important is how easily it can be identified—and ruled out—with a simple intraoral palpation of the temporalis tendon. For doctors treating head and facial pain, awareness and examination of this tendon attachment should be routine. Doing so can help patients avoid unnecessary treatments and prolonged discomfort.

Thanks for taking a moment to read this overview of temporalis tendonitis. I hope it offers a helpful perspective on this very common facial pain problem. As always, please feel free to give me a call if I can be of any help.

Warm Regards,
