Home remedies such as applying clove oil, rinsing with salt water or hydrogen peroxide, and applying ice can quickly and temporarily relieve tooth pain until you can reach a dentist. Clove oil contains eugenol, which is a natural anesthetic, but it can make pain worse on sensitive gum areas.
Rinsing with a teaspoon of salt dissolved in 1 cup of water can reduce pain and swelling. Hydrogen peroxide, myrrh and peppermint tea are also good rinses for reducing inflammation. Swish these rinses in your mouth for 30 seconds, and then spit them out. Icing the tooth can help numb the nerves to reduce pain.
