The accidental displacement of a root into the maxillary sinus is a recognized complication of exodontia. Such roots should normally be removed early rather than late in order to minimize the likelihood of maxillary sinus complications. A root left within the maxillary sinus may, on occasion, pass spontaneously into the nose. Appropriate treatment and possible complications are discussed.
