Hi.. Can understand your concern.. As per your complain if you have got your wisdom tooth removed and you still have three days left for you to fly you need not to worry as the healing will be progressive by that time provided if there is not complication like dislodgement of clot and you can very much fly as the air journey does not effect the healing of the extraction socket.. The only thing that can happen is that with change in pressure at the higher altitude there can be congestion in sinus and as the upper wisdom tooth lie in close contact with the sinus there are chances that you have a comparatively more soreness or tenderness in the extraction region,other than that there is not effect on healing and it will continue the way it should be normally.. Just follow the instructions and medications (especially antibiotics to prevent any infections) advised to you by your dentist and maintain the clot in position by not spitting or gargling very vigorously.. Hope this information helps.. If you find the answer helpful please write a positive review and click on find this answer helpful as a token of appreciation.. Thanks and regards..
