Really? I never knew that worked... Thanks. :)
i hope it works for you and forreste, i get them sometimes and they take for-ever to go away unless i put baking soda on them. just keep putting it on there until they are completely gone, esp right before you go to bed
I have the worst canker sore in the world going on right now. I tried the baking soda and it made my mouth salivate so much I couldn't sleep comfortably. I am still going to keep on trying tho, this thing hurts like hades.
