Giant Cell Arteritis Masquerading as Tooth Pain: A Case Report.

Giant cell arteritis (GCA) is a form of vasculitis characterized by symptoms that often lead a patient to consult a general dentist. Its rarity in the dental setting and serious life-altering effects make it a formidable diagnosis. We discuss a case of a 60-year-old female with GCA presenting with primary symptoms of excruciating tooth and jaw pain on the left side. We also report secondary symptoms of headache and partial vision loss and engage in a review of the relevant literature. Jaw pain, unexplained toothache, or tissue necrosis in patients aged over 50 years can be misdiagnosed as joint arthritis or temporomandibular disease (TMD), which could lead to severe consequences. Accurately diagnosing this ophthalmic emergency is critical for implementing therapy promptly and preventing ischemic complications. Dentists should maintain a high index of suspicion about its signs and symptoms, which will aid in making an early diagnosis and prompt referral.
