Supernumerary teeth are more frequent in the permanent dentition of the maxilla, and prevalent in male gender. Their presence may cause delay at adjacent teeth eruption, malocclusion, cystic formation, and root resorption. Since fourth molar presence is rare, early diagnosis is the key to accurate conduct and reduction of injuries at the time of its extraction. That is based on a thorough clinical evaluation and appropriate complementary exams. A twenty-one-year-old male patient, with no relevant medical history, presented for extraction of the third and fourth molars, with absence of pain or sensorial complaints. After clinical exam, radiographic, and computed tomography an analysis, the treatment plan was extraction of all third and fourth molars. Surgical procedure employed was effective in removing the included teeth, with adequate surgical time and no postoperative complications. Early diagnosis along with correct treatment planning through imaging exams such as computed tomography is of great value for success in the management of retained and supernumerary teeth.
