She underwent surgery by anterior rhinoscopy and endoscopic guidance. The patient's symptoms were resolved completely post-operatively and remained symptom-free for 18 months postoperatively.

Ectopic intranasal tooth arising from inferior turbinate is very rare. No clear etiological factor has been suggested in most of the reported cases. Idiopathic etiology has been described as an etiologic factor for ectopic teeth. The treatment of intranasal teeth is early surgical extraction to alleviate the symptoms and prevent the possible morbidities.
