Ectopic and supernumerary teeth occur in a wide variety of sites. Those that have been reported include the mandibular condyle, coronoid process, orbit, palate, nasal cavity and the maxillary antrum. Eruption of teeth into these sites is rare, and easily overlooked. We present two cases in which eruption of teeth into the nose and paranasal sinuses was associated with significant morbidity and show how this was relieved by appropriate surgery.
