Intrusion is defined as displacement of a tooth into the alveolar bone. In this report, we presented a patient with 15 years of delayed diagnosis of maxillary teeth intrusion into the nasal cavity. A 30-year-old male presented to our clinic with nasal discharge. He had been in a traffic accident 15 years ago. Radiographic examination revealed intrusion of two anterior teeth into the nasal cavity. In patients with maxillofacial trauma, the possibility of having an accompanying dentoalveolar trauma must always be kept in mind. While a computerized tomography (CT) scan is useful in diagnosis of such traumas, it must be performed in all patients with maxillofacial trauma to avoid misdiagnosis.
