nyuszisue,

There is no herb or other that can cure a tooth infection. Some things may <<temporarily>> reduce the inflammation, but the infection will still be present. The species of bacteria that reside inside of an infected tooth will become varied and profuse. The same is true for an infection in the jaw bone after a tooth has been extracted.

Oil of oregano, garlic, turmeric, clove oil, etc.... are all great properties for reducing bacteria and inflammation. In cases other than teeth or jaw bone these things can eliminate certain types of bacterial infections. Depending on the severity and location of the infection, most of the time they have to be used in quantity and longevity to be truly affective and usually topically and internally.
