hiii, I have gone through your query, and I can understand through the painful situation you are going from because post extraction pain as per in your case is call
DRY SOCKET which is a very painful condition,occurs because of secondary infection to the extraction site.
in this condition you must visit your
dentist for the cleaning of the extraction wound,because this can't be handle at only
home care.
your dentist would clean the area thoroughly and place the medicated pack to the wound.
you have to take antibiotics and pain killer medication prescribed by doctor to reduce the inflammation and pain.
some tips that you have to do at home are :
1) Add 1 tsp of salt to the luke warm ( not so hot )water and do the gargle with it, 2-3 times a day.
2) if you smokes,then you strictly have to stop
smoking for some days until the wound heals.
3)try to keep mouth as clean as possible.
Don't worry the pain goes away as soon as the dressing is given and proper medications are taken,the wound will heals by itself.
