Canker sore...help!?

It's been 9 days and I've done the gargling of warm water with salt already. It won't go away. It's just one canker sore on my lower lip and it's so painful. I can't eat comfortably and I have to hold my lip with my left fingers to brush my teeth daily. Help!
Its going to hurt a lot at first, but try gargling with original Listerine several times a day. It seems to speed up the process of healing and kind of dulls the pain for a little while.

Also, you might want to try switching to a toothpaste that Doesn't have SLS (Sodium Lauryl Sulfate). I notice that I don't get as many Canker Sores if I use an SLS-free toothpaste.

I really hope this helps you! I know how much they hurt. : (
