A cat infected with feline immunodeficiency virus presented with a history of chronic sneezing and right-sided mucopurulent nasal discharge and underwent a dental cleaning. At that time, a fractured right maxillary canine tooth (104) was extracted. Clinical signs resolved after the procedure. One month later, the unilateral mucopurulent nasal discharge and sneezing recurred. A small fistula was found in the area of 104. Radiography and rhinoscopic examination revealed a large tooth root—likely retropulsed during the extraction of 104—in the right nasal cavity, occluding the meatus. The sneezing and nasal discharge resolved after removal of the root fragment with endoscopic grasping forceps.
