A toothache is one of the most debilitating and acute pains that we can suffer. The origin of a toothache is usually caries or an irritation of the tooth nerve. The wearing down of teeth enamel or teeth grinding (bruxism) can also be the cause of pain. Emergency treatment will consist in relieving pain through anesthesia in the clinic and providing anti-inflammatory and antibiotic treatment if necessary. Sometimes it is also necessary to remove the infection with a small incision on the gum with local anesthesia or via the same tooth. On other occasions it may require endodontic (killing the nerve) of the affected tooth.
