A three year old pacific walrus wore its tusks down within 30mm from the gingival margin. No pulp exposure was created but an infra-orbital sinus tract developed on the left side draining purulent material. Under general anaesthetic the tusk was extracted surgically, the socket curetted to a healthy base and the sinus tract opened for further drainage. Recovery was uneventful and the sinus tract was almost healed two weeks postoperatively.
