salt. cure with 1 or 2 days. sometimes overnight for me.
and the sensation is wonderful.

Putting salt is no doubt painful. But it's the fastest way for me. And like beck_ken said, no pain no gain.
The pain is only initially anyway, after that there's no pain edi. So when I have an ulcer, I put salt as many times as possible, mainly cause I like the feeling.
But I think too many times isn't good as the gum tends to become like.. I dunno how to put it in words.

salt isn't all that bad. the food you take also has salt wan ma.
drink more water also la. after all, drink more water can help cure the ulcer too. If not mistaken, mouth ulcer is caused by too much heat in the stomach.

That's new! I'll try it next time I have an ulcer.

Lol! You're suppose to gargle at the lowest of your throat when you gargle listerine la. It works wonders when one is having sore throat.
Try Bactidol. The taste is horrible but it numbs the throat right after you gargle. Works very well for me.

If at the side of the mouth then salt will be damn painful. Try using oral paste. I don't like oral paste thou. Like something very kacau in my mouth.

i dun really like bonjela as it's not very effective on me.
i used to like the chinese green powder but since i found out about the salt, i've never use any other methods to cure my ulcer edi.
