Are you sure it isn't just a case of thrush? I had that and my entire mouth had a white coating on the inside. My doctor prescribed diflucan. You just take one pill per day and it usually clears up in about three days. Just a suggestion as to what it might be, but I hope you get it taken care of. Thrush wasn't painful, but it was definitely a nuisance...
