Abstract: When an upper tooth is extracted a possible complication is the creation of an oro-antral communication with the added risk of displacement of tooth roots into the antrum. We present a case of a displaced palatal root of an upper first molar tooth which was found in a superior position in the maxillary antrum having been left in situ for 6 weeks. The root was in a high risk position for complications such as sinusitis, mucocoele formation and the more serious septic thrombosis of the cavernous sinus. This case report describes its safe endoscopic removal and highlights the importance of prompt referral and treatment for similar cases.

Clinical relevance: Displaced roots in the maxillary antrum during routine extraction can result in complications ranging from sinusitis to more severe complications if not managed appropriately.
