Hi..
Can understand your concern.
The condition which you explained about your wisdom tooth appears to be "PERICORONITIS".
It is at times very painful along with swelling of gums around and over the
impacted wisdom tooth.
With antibiotics , painkillers and warm saline gargles the swelling and pain subsides but may (not necessarily) reappear after a few days as medicines can give only short term relief.
The swelling happens due to either deposition of food particles in between the gum flap and the wisdom tooth or due to continuous trauma to the gum flap by of the opposite arch tooth.
The best thing you should do is to keep the area clean till you are out of town and can do warm saline gargles twice daily and take medicines as prescribed by your
dentist.
After you come back get your wisdom tooth evaluated by getting an IOPAR (x-ray) done to find out whether the tooth is impacted(
impacted tooth does not erupt completely) or will erupt in proper occlusion.
If it is impacted the best thing to do is to get it removed and if it can erupt to occlusion you can just get the overlying gum flap removed to get complete relief from the problem.
Hope your problem get solved.
Thanks and regards..
