I get serious canker sores a few times a year and they made me miserable for a couple of weeks each -- until I found cankermelts. They don't eliminate the sores completely, but they do lessen the pain and speed the healing. I had no relief at all before them. I do have trouble sticking them in my mouth, though, and sometimes I swallow them too soon.
