Patients can relieve toothache swelling and pain by applying a cool compress to the outside of the mouth and taking over-the-counter pain medication such as ibuprofen or acetaminophen, according to WebMD. It helps to keep the mouth clean by rinsing with warm water and gently flossing around the affected area.
Applying an antiseptic with benzocaine or oil of cloves directly on the tooth and gums can also help relieve pain, according to Mayo Clinic. It is counterproductive to put aspirin directly on the tooth or gums, since it can burn gum tissue. If toothache pain persists or the pain is accompanied by jaw pain or a popping and clicking jaw, the patient should contact a dentist for professional assistance.
