greetings to u! I m glad that I will be able to clear ur doubt. There is very less possibility that wisdom tooth removal pain lasts for this long unless it is a traumatic extraction. I would also like to point out that the healing time varies with every person. The gum opening up can be because of vigorous gargling resulting in loss of the healing tissue and bone exposure. But this is very uncommon. Next the bone kind of thing and tonsil kind of thing that popped out could be the healing tissue as I ve stated before. All these might have resulted in an opening rather communication between his mouth and nose, the reason for his difficulty in blowing his nose. This can be corrected by a small surgical procedure(if required, which has to be decided by ur treating dentist/oral surgeon) Till then avoid vigorous gargling, blowing nose, sucking and sneezing. In case of sneezing please close ur mouth and nose with ur hands. This is not an emergency situation, so be cool. Hope this helped u. Thank u Regards, Dr. Ramprasad
