A drop of oil of oregano in olive oil was the only thing that worked for me and I mean even with drug pain killers, cloves, etc. Gave me a month to mull over letting go of dead tooth with abscess at the end (which I finally did). Now I have read that if one takes big therapeutic doses of super duper enzymes (the context was about hi-zymes), one can knock out the infection in 3 days.
good luck
