HOW TO ELIMINATE CANKER SORES:
Dissolve one-half teaspoon baking soda in a half cup of warm water and use as a mouthwash. Soak a cotton swab or cloth in castor oil and apply it directly to the canker sore. Apply a wet tea bag for temporary pain relieve. And once the sore has started to heal, gently apply some Vitamin E oil to the area.
