Salt water is like a magic. I get canker sores time by time and you know how painful they are. When I get them, I will just rinse my mouth with warm salt water, and most of the pain will go away.
I know what you are talking about. I get canker sores almost regularly, and gargling with salt water will always help much with it. No, it wouldn't cure the sores, but at least it would help you get rid of the pain.
