Read my post to you again, google the things I mention so you understand better. ;-)
Rife therapy, oregano essential oil, cinnamon essential oil, oil pulling, zappers.
In the long term just get the tooth pulled and oil pull with olive oil with as many drops of oregano essential oil mixed into the olive oil as possible, especially during the healing phase so you don't develop cavitations.
(As many drops as possible- aka, that doesn't make you herx/feel very sick. 1 drop per tablespoon is a good place to start, or all the way down to 1 drop per 3 tablespoons, and store the other oil that won't fit in your mouth for later pulling sessions. )
Root canalled teeth are very expensive to keep from spreading health problems.
