Supernumerary nasal tooth in close proximity to a dental implant.

Supernumerary nasal teeth (SNT) are a rare phenomenon. Supernumerary teeth occur in 0.1 to 1% of the population. They are most commonly found in the upper incisor area, when they are known as mesiodentes. They also are fairly common elsewhere on the intraoral palate and in the maxillary sinus. Nasal teeth are quite rare, with only case reports and small case series found in the literature. SNT can present with different symptoms, including unilateral nasal obstruction, nasal drainage, and infections, or they can be asymptomatic and found incidentally. This report describes a case of a nasal tooth in close proximity to a noninfected dental implant that became symptomatic with unilateral nasal obstruction. The diagnosis was based on endoscopic and radiologic findings, and the patient's symptoms resolved after endoscopic surgical removal of the tooth through the nasal cavity.
