Dental infections may lead to severe local or systemic infections such as endocarditis, brain abscesses and mediastinitis. Fever may be the only symptom. Early dental evaluation and referral of patients with persistent and recurrent fever (even without any oral symptoms) to a dentist has a critical role to prevent unnecessary, time-consuming further diagnostic tests and invasive procedures. A simple panoramic radiography may be useful to establish the diagnosis. Herein, we aim to report a rare clinical condition caused by odontogenic infections; unexplained or recurrent fever related to dental abscess.
