Large parts of odontogenic infections originate from pulpal necrosis with bacterial invasion in the periapical and periodontal tissue, which may lead to the formation of an abscess. When this purulent collection is not able to drain through the skin surface or into the buccal cavity, the abscess may extend diffusely through the fascial planes of soft tissues, leading to a pathology called cellulitis. Ludwig's angina is a diffuse cellulitis in the submandibular, sublingual, and submental spaces, characterized by its propensity to spread rapidly to the surrounding tissues. Early recognition and treatment for Ludwig's angina are of paramount importance due to the myriad of complications that can occur in association with Ludwig's angina. Serious complications resulting from these conditions, such as cavernous sinus thrombosis, cerebral abscess, or death of the patient may occur if proper treatment is not performed. Thus, the treatment of choice of this condition should be maintenance of the airways, incision and drainage of the purulent collection, broad-spectrum antibiotic therapy and especially the elimination of infectious focus. The objective of this study is to present a case of facial cellulitis and Ludwig’s angina of odontogenic origin, involving an adult patient, smoker and with poor oral hygiene, who exhibited an acute inflammatory process. The proposed treatment is necessary to the association of drug therapy, immediate drainage of the purulent collection and extraction of the dental element responsible for the infection in order to provide immediate patient well-being.
