Have you givin her motrin or teething tablets, all though you think she has all of her teeth doesn't mean she isn't getting more. I have a friend who's child got two sets of baby teeth.Or can you see anything in her mouth. My son did the same thing. He had a few small canker sores in his mouth down around the bottom of his gum line. I used some canker sore medicine. it was all better. check that first.
