Dentoalveolar injuries are common and are caused by many factors. Dental trauma requires special consideration when a missing tooth or tooth fracture accompanies soft tissue laceration. A tooth or its fragment occasionally penetrates into soft tissue and may cause severe complications. This report presents a case of delayed diagnosis and management of a displaced tooth in the vestibule of the mouth following dentoalveolar injury. This report suggests that radiography can lead to an early diagnosis and surgical removal of an embedded tooth in the soft tissue.
