Intranasal ectopic dentition is a rare clinical entity. The presence of teeth has been reported in ovaries, testes, anterior mediastinum, and pre-sacral regions. In the maxillofacial region, teeth have been found in maxillary sinus, mandibular condyle, coronoid process, chin, nose, and even orbit. The conditions commonly associated with an increased prevalence of ectopic teeth include cleft lip and palate, cleidocranial dysplasia and Gardner syndrome. Intranasal teeth can cause problems such as nasal obstruction, chronic rhinorrhoea and speech problems. The most common ectopic tooth which appears in the maxillary midline is called a mesiodens. This unusual situation should be suspected in patients with nasal obstruction and unilateral fetid purulent rhinorrhoea.
