Clove Oil Numbs A Toothache
Since the 19th century, dentists have used clove oil to relieve toothaches. But what does science say about it? A 2013 study agrees that clove oil can numb tooth pain because of an antioxidant called eugenol. However, other researchers argue that the method requires needle injection for the best results.
That said, clove oil continues to be a popular home remedy. Ayurveda expert Dr. Ashutosh Gautam says that clove oil reduces swelling and increases blood flow to the area. If you don’t have the oil (do not use the essential oil), you can suck on a raw clove.
