Clove Oil - The best one!!!!!! Cloves contain a natural anesthetic called eugenol, which numbs whatever it comes in contact with. Drip a drop or two of the oil onto a cotton ball and apply it to the throbbing tooth. Clove oil may numb the affected area temporarily, but it is short-term relief lasting only a few minutes.
Place a small ice cube in a plastic bag, wrap a thin cloth around the bag, and apply it to the aching tooth for about 15 minutes to numb the nerves. Alternatively, that ice pack can go on your cheek, over the painful tooth. Also, according to folklore, if you massage your hand with an ice cube, you can help relieve a toothache. When nerves in your fingers send "cold" signals to your brain, they may override the pain signals coming from your tooth. Just wrap up an ice cube in a thin cloth and massage it in the fleshy area between your thumb and forefinger.
