What are some home remedies for canker sores? Anything for the pain?

There are medications you can take orally, however I recommend a mouth wash called Peroxyl. It helps them to heal faster by cleaning any bad bacteria that settles in the area. The few times I have had them, it neutralized the pain. If you go to a dentist they will have stuff to put on the area. Typically they will apply it. The stuff they have may help it to heal faster also.
