Oregano oil. Oregano oil is derived from the potent oregano plant. This oil is prized for its antioxidants and antibacterial properties. The two powers of this oil combined can combat the pain and damage done to an abscessed tooth. To use the oil, it should be diluted with a carrier oil so it does not burn the wound. To use it safely, a few drops of the oil are mixed with an ounce of carrier oil. A cotton swab or ball can be dipped in the mixture and held over the painful area for a few minutes. After removing the swab or ball, the mixture can be left for 10 more minutes before it is rinsed off the teeth with water. This can be repeated three times daily.
