Buy some garlic. Rip off the layers. Pull out a clove. Break it open. Chew it in the infected area of your mouth. Before it comes too painful, well add water to your mouth and oil-pull with it. Swischhh with it. It is incredibely painful. The longer you hold out, the better. Do it repeatedly. No pain no gain. It kills most infections on contact. Ultimately you may be dealing with a dead tooth though. Just don't know. But it may get you by....
