I can't express how important it is to take care of oral health issues. Whatever infection that is in your teeth and gums can settle down into the rest of your body and cause you very serious health issues in the future. I realize a good dentist is very expensive but getting this kind of infection taken care of is priceless. So of course my first suggestion is to get to a dentist as soon as possible. Until then, I'd suggest you try rinsing your mouth several times a day with warm salt water. This should help relieve the infection in your gums. You could also try rubbing some whisky on your gums to relieve the pain. Many old timers used do this to help relieve the pain of their babies teething.
