Thanks for all the good suggestions. I found the Rincinol worked really well for me. And then I got some Gelclair and found it's the same ingredients as the Rincinol. I high recommend this to anyone who's suffering from mouth sores. My "blisters" finally got smaller and are now gone after about 10 days. As many people have said, you just have to wait these things out...but the Rincinol/Gelclair realy did help a lot.
