Pack an obvious cavity with clove oil. Clove oil is a natural remedy that is used to lessen pain associated with a tooth that has a cavity. When the cavity is visible, take a toothpick that is topped with a small piece of cotton and gently clean out the cavity. Then, rinse your mouth out with half and half solution of warm water and peroxide. Squirt a few drops of clove oil on a small wad of cotton and gently pack it into the cavity.
