Can i fly 3 weeks after molar extraction? it did develope drysocket but was treated for 4 days now no pain just ache and healing yellow whitish stuff.

Yes: Yes you can fly. Be sure to take some extra gauze in case your socket starts to weep while on board the plane. Other then that there should be no limitations to your travel.

dry socket: Sounds good sounds like dry socket treamtent worked otherwise you would still have bad pain. Flying 3 weeks later should be ok but ck with the dentist.

Yes: If it is not hurting you, yes it is safe to fly. A dry socket is when the blood clot was washed out of the socket and left the bone uncovered. Uncovered bone does not heal and hurts. If you are not hurting, then the bone has been covered enough for flying.
