I know this sounds REALLY gross... but have you ever used a salt water solution? if you garggle with two teaspoons of salt in a cup of water (rember to spit it out... its so nasty you don't want to swallow) with in a couple of days the sores will have healed. I know I've got to do this everyother week and especially during my menstration... I get a mouthfull of white sores and it seems to work pretty good. I hope this helps.
