Yes Clove Oil is a great way to get rid of a toothache due it's antibacterial, anesthetic, anti-inflammatory and antifungal properties.
To get rid of your toothache using Clove Oil apply some clove oil to a cotton ball or Cotton Swab and apply the clove oil to the gums where the tooth pain is.
I always use Clove Oil when I have a toothache and it works really great for toothaches.
