I have found that one of the best things to alleviate the pain of a toothache is to chew cinnamon gum, like "Big Red" and wrap the partially chewed gum abound the aching tooth. The cinnamon oil in the gum deadens the exposed nerve and eliminates the pain. If the pain is from under the gum line, though, this won't work. This remedy has proved to be a huge blessing while you are waiting to get to the dentist. So, you might want to add a supply of cinnamon gum to your survival supplies.
