Differential Diagnosis of Mandible Pain

Primary Differential Categories

The American College of Physicians recommends that the most common non-dental causes of mandible pain are temporomandibular disorders (TMD), particularly myalgia of the masticatory muscles, followed by neuropathic pain conditions and, less commonly, serious conditions like giant cell arteritis or malignancy that must not be missed 1, 2
The British Medical Association suggests that myalgia is the most prevalent TMD subtype, characterized by continuous bilateral or unilateral pain in muscles of mastication, worsened by jaw movement, chewing, or clenching 3, 1

The American Academy of Neurology recommends that post-traumatic trigeminal neuropathy is characterized by continuous burning/tingling pain following dental procedures or facial trauma, often with allodynia or sensory changes 1, 2
The American Dental Association suggests that atypical odontalgia is a localized continuous burning pain in tooth-bearing area without identifiable dental pathology 1, 2

The American College of Rheumatology recommends that giant cell arteritis is characterized by unilateral temporal/jaw pain in patients >50 years old, jaw claudication, and associated temporal artery tenderness, visual symptoms, elevated ESR/CRP 1, 5
The National Comprehensive Cancer Network suggests that malignancy is characterized by progressive unilateral neuropathic pain, non-healing ulcers, masses, unexplained tooth mobility, paresthesias, cranial nerve deficits, weight loss, and night pain 1, 2

The American Academy of Family Physicians recommends that the initial diagnostic approach should include a thorough history and physical examination, including timing patterns, pain quality, aggravating factors, and associated features 2, 3

The American College of Physicians recommends that the first-line conservative approach for TMD should include patient education and reassurance, jaw rest, heat and/or cold therapy, NSAIDs for pain and inflammation, and supervised jaw exercises and stretching 3, 5
The American Academy of Neurology suggests that neuropathic pain medications, such as tricyclic antidepressants, gabapentin, and pregabalin, should be used for post-traumatic trigeminal neuropathy and atypical odontalgia 1, 2
The American Dental Association recommends that carbamazepine should be used as first-line treatment for trigeminal neuralgia 5
