The best way to clear up a canker sore is truly putting baking soda directly on it. I went to the doctor with a mouthful of canker sores and they didn't have a clue. The sores were so bad I couldn't even eat or talk. I decided to burn those suckers off with baking soda and within two days they were gone! Love my baking soda. It does sting, but if you keep applying until it doesn't sting anymore, it will feel better.

I have canker sores often and have used may different home remedies, over the counter medication without great success. A friend told me to rinse the area with lemon juice.
