Hi A.,
I'm not a big medicine pusher if it isn't necessary, but when it came to teeth issues with my son, I'd give it if I thought it might remotely help. Ibuprofen seemed to really alleviate tooth/gum pain (when that's what it was-which was often) and allowed my son to relax better and fall asleep. It wasn't because he was medicated that made him sleep-that stuff doesn't make him drowsy. I believe it was really because it took some of the discomfort away and made it easier to sleep. I always thought it was worth a try to help him out (and me too) and it won't hurt her to give her a bit here and there.
Good Luck!
