If that infection gets into your bloodstream it can kill you! Happened to my ex's best friend. The dentist probably won't pull it until the infection is gone either. Get some antibiotics.

Take a teabag, empty it, cut it down to create a pouch and fill with 1/4 tsp of powdered cloves, Moisten it with warm water and put it between the tooth and gum. It tastes nasty but really works! This helped me through a tooth that was so painful- it was worse than childbirth and a gall bladder attack that turned into pancreatitis requiring emergency surgery. Bite the bullet and have a dentist pull it.
