I am not sure is it gumache or toothache but it is there for last 3days. Gum has swelling even it is feel able and visible from outside. Swelling is up to left ear from jaw and on left cheek up to nose. Some time it pains severely and pain moves. Sometimes i feel severe pain in left side back tooth. if I try to open full mouth then throbbing pain happens. I took tab IMOL it gives relief but for shorter time. What is this toothache or Gum ache or Gum swelling? Suggest me some medicines & advice.
