The inflammation of the nerve of the tooth will cause pain, and is often the most uncomfortable pain. If you elevate your head when resting, some of the pressure in the area of the toothache may diminish.
Using eugenol at home may help reduce pain from a toothache. Soak a small piece of cotton in the oil, then blot the cotton on a piece of tissue to remove the excess. Using a clean pair of tweezers, hold the cotton on the painful tooth for 10 seconds, making sure you do not swallow any of the oil.
