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 (1 part hydrogen peroxide�to 1�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.
