Question:
How can you treat painful canker sores in your mouth?

Answer:
The easiest home remedy is to apply hydrogen peroxide with a cotton swab on the canker sore (one part hydrogen peroxide and one part water). Then dab a small amount of milk of magnesia on the canker sore 3-4 times a day. This is not only soothing, but appears to help healing. See canker sores.
