I once read that oregeno oil was great for toothaches and one day I got to prove it. I was experiencing a pretty bad tooache so I ran out to GNC and bought the oil. A little expence, but goes a long way. Applied it and I swear within an hour or less (been awhile can't remember) my toothache was gone and never came back. Some people can't stand the taste but I love oregeno so no prob for me.
