Try it when: You have a mouth sore or a toothache.
How it works: “Eugenol, a chemical in clove-bud oil, is analgesic and antibacterial, which makes it effective for treating pain in the mouth,” says dentist Jonathan B. Levine, the director of the New York University CE Advanced Aesthetics Program in Dentistry, in New York City. (In fact, dentists mix it with zinc oxide to use in temporary fillings.) Mix 1 drop in 1 cup of water; apply directly with a cotton swab.
Good to know: Gargling with a mixture of water and 1 drop of clove-bud oil can help neutralize bad breath.(But don’t swallow. The oil can cause an upset stomach.)
