Talon cusp is a rare odontogenic developmental anomaly with male predilection and multifactorial etiology. It projects as an accessory cusp-like structure from the cingulum area or the cement enamel junction (CEJ) affecting both primary and permanent dentition. It is imperative to clinically examine the developing dentition for occlusal harmony, especially in children with this anomaly. This report highlights facial cellulitis as a complication arising from a type I taloned maxillary lateral incisor and its endodontic management in a female pediatric patient. It emphasizes the clinical significance, early diagnosis, and prompt prophylactic management of the talon cusp so as to prevent the development of acute sequelae in children.
