Arteriovenous malformation (AVM) of the mandible is a rare vascular condition that can manifest as a wide range of symptoms and, on rare occasions, cause fatal hemorrhage. The symptoms of mandibular AVM can range from soft tissue swelling and tooth mobility to severe hemorrhage. The recognition of early symptoms is crucial for the prevention of a fatal hemorrhage and for the proper diagnosis and treatment of mandibular AVM. For emergency hemostasis of a ruptured mandibular AVM, manual compression with gauze, topical thrombin, absorbable hemostat, suturing the lesion, and replanting the extracted tooth is recommended. Multiple treatment options for mandibular AVM are available, such as arterial embolization, venous embolization, direct surgical closure, and bone resection. A combination of treatment options should be considered in complicated cases. We report a case of a 10-year-old girl with a previous history of telangiectasia on the right cheek presented with cardiac arrest resulting from massive bleeding immediately after a tooth extraction.
