Presenting issue:

Unilateral sneezing—left hand side, gingival inflammation, and gingival recession with apparent extrusion of tooth 204 and intrinsic discolouration of crown of tooth 204.

Possible causes:

Trauma due to a fight, motor car accident, blunt trauma or abrasion injury from bones or another hard object.


Pulp necrosis of tooth 204 with inflammatory apical root resorption and oronasal fistula, confirmed with intra-oral X-rays.

Due to the extent of the root resorption, root canal therapy was a poor option with low chance of success. Extraction with removal of all tooth structure, curettage of the alveolus and repair of the oronasal fistula with a buccal mucoperiosteal advancement flap was necessary.
