Small but painful, canker sores are tiny round ulcers inside the mouth, not on the lips. They do not spread and often appear after eating too many fatty foods. While they usually heal on their own, the pain can be intense. Use the mouthwash from #2—one to two teaspoons of baking soda in half a glass of water—daily if you have a sore. Studies indicate this can reduce pain and support healing.
