Just to make sure..I hear a lot on these forums that canker sores are not herpes..this is true, correct?
If you suspect this is something other than your usual canker sores - follow up on it with your provider. Also take a look at things like chewing gum ( no cinnamon flavor ) , mouthwashes and toothpastes - no whitening, tartar control, complete, total or strongly flavored ones.
