Abstract
Background and Aim: Odontogenic infections of the head and neck region are clinically significant due to their proximity to vital structures. Periapical lesions from untreated dental caries or trauma, may progress beyond the periapical area into deep fascial spaces of the neck, leading to cellulitis, abscess formation, or potentially life-threatening complications such as Ludwig’s angina. Case Report: A 20 year-old female patient who presented with recurrent pain and swelling on the right side of her neck, ultimately identified as being caused by a periapical periodontitis infection originating from a mandibular right lateral tooth(#26). Despite undergoing multiple neck surgeries over a 5-month period, the underlying dental cause remained undiagnosed. Root canal therapy on the affected tooth successfully resolved both the dental infection and the recurrent neck swelling. The patient was followed up for 7 years with no recurrence of the symptoms.
