For abcessed tooth - Put a small amout of hydrogen peroxide in mouth in the area of the tooth - swish around for about 5 minutes, spit it out, and rinse with warm salt water. It may have to be done several times until the abcess begins to drain. If you have to repeat it, wait an hour or so before doing it. I also take Echinacea and Goldenseal and garlic capsules and take Ibuprofen if needed for pain. Ssome pain can be relieved temporarily with a hot cloth applied to the face in the area of the offending tooth.
