The untimely treatment of odontogenic infections is accompanied by a life-threatening complication, acute descending necrotizing mediastinitis (ADNDM), defined as an inflammation of the connective tissues and structures within the mediastinum. The mortality is approximately 11% to 41%, caused by sepsis and organ failure. Medical decisions are critical because diagnosis and treatment delay are the primary cofactors associated with mortality. Early surgical treatment is the most important aspect in the management, requiring, in most cases, treatment in the intensive care unit (ICU). We present the clinical case of a 39-year-old male patient, diabetic, who was admitted to the emergency room for a dental abscess with 4 days of evolution. After the complementary examinations, an inflammatory process was confirmed that extended from the floor of the mouth to the mediastinum, compatible with an MNDA; the patient required several surgical interventions and management in ICU for more than 30 days with favorable evolution and subsequent discharge.
