you lot are wusses.
The reason a mouth ulcer won't heal is cos of the white coating over it.... it's some horrible attempt at self defense by the body and it fails.
The way to cure it hurts like hell but works
Use your tooth brush on it...hard! really hard...it'll hurt like crazy for about 5-10 seconds and then....it'll stop. The body's natural pain killers work fast if you scrub HARD.
Then you put fresh salt on a clean finger and press it in. You may pass out now....but keep your fionger there as you topple.
And that's it...it'll heal really fast. You've opened the wound, cleaned it and sterilised it with salt...and it'll be gone within a day or two..
If you LEAVE it...with that horrible white coating on it....the moth's saliva stops it healing.
All of what I've typed is what I do and it works...but it hurts like hell.....really hurts
No pain...no gain
