The sodium hypochlorite is widely used in endodontic treatment. While it is effective solution for disinfection of root canal system, complications during canal irrigation are rarely reported, especially in primary teeth. This report demonstrates that sodium hypochlorite extruding through the root apex might cause severe complications. A 4-year-old female patient was referred from local dental clinic to the emergency room for the management of sudden facial swelling and pain during re-endodontic treatment of the maxillary primary central incisor using sodium hypochlorite. The patient was given systemic steroids, antihistamines, antibiotics and analgesics and the maxillary primary central incisor was extracted to prevent secondary infection. Swelling began to subside after 2 days. A negative result was obtained from skin patch test with sodium hypochlorite. Thorough care must be taken in primary teeth to prevent the inadvertent injection of sodium hypochlorite to periapical tissues during root canal irrigation. When adverse reaction occurs, proper management such as analgesia, cold compression and adequate medication should be done.
