What gets rid of canker sores?
A canker sore is nothing more than a small ulcer in the mouth. To rid yourself of it, almost overnight, all you have to do is mix up a paste of baking soda and water, get a finger-load, and stuff it gently right on top of the canker sore and let it stay there as long as you can. It will neutralize the acid in the sore, and rid you of it very quickly.
