For some reason whenever I am stressed my body lets it out in the form of mouth ulcers. Which just adds to the annoyance of my busy days. Luckily I found Kanka which is a brown liquid goo that you apply by dabbing it on to your your mouth pain, I believe it also works for people with braces, or even if you just cut your gum! Anyhow, mouth sores I seem to be buying gallons of this stuff!
Once applied it feels like your pain has been sealed up with a kind of dry powder, it's a really weird sensation. It does work though, almost instantly the pain is soothed at it stays like that for at least a couple of hours before you have to reaply. Overall it works far better than any other medication I've tried such as spray on so I don't really know what I'd do without it. The only real dissadvantage to this is if you get it on your skin it doesn't come off and will make that area go numb for a while so it's important to be wary of that problem. But if you have a similar problem to me this is definatly the stuff to get.
