What it is and what it is used for

Clove essential oil (eugenol), from the dried flower buds of Syzygium aromaticum, dabbed on a painful tooth. Folk practice was simpler: press a whole clove against the aching tooth. A clinical trial found clove gel roughly equal to 20% benzocaine for toothache, and laboratory work shows eugenol blocks the same sodium channels that dental anesthetics target.

Folk history

Before the dentist's needle, there was the clove. Across Indonesia, China, and South Asia, people pressed cloves onto aching teeth for centuries — the bud numbs the mouth on contact. European dentists adopted oil of cloves in the 19th century, and eugenol is still used in dental cements and temporary fillings today.
