question: I had root canal surgery done about 2-3 weeks ago. It was fine for a little while but then my tooth started to hurt, so i used whiskey to numb the pain. I left it on too long and it burned my gums. Now my cheek and gums are swollen, but i can also feel pain in the roots of the tooth. Do you think the swelling is caused by an infection, or the burn. Thanks,Dom
