Cloves
Cloves have been a common treatment option for toothache throughout history. The oil can effectively numb the pain and reduce inflammation. Part of the properties of clove is eugenol, which is a natural antiseptic [2].
To apply this remedy, dilute clove oil with a carrier oil, like jojoba or sunflower oil. The National Association of Holistic Aromatherapy [3] recommends a ratio of about 15 drops of clove oil to one ounce of carrier oil.
Then, dab a small amount of the diluted oil onto a cotton ball and apply it to the affected area multiple times daily. You can also add a drop of clove oil to a glass of water and use it to rinse your mouth.
