You could try giving meds in the middle of the night, say 3am, kind of like a dream feed (go in, squeeze in the meds and then help resettle if needed) to see if she sleeps longer in the morning. My DD was a predictable EWer with teeth.

I know it's hard to push the A time when they EW, but even if you can do it by 5min every few days, that might help. The problem is, if her body knows it's going back to sleep at 9am, it doesn't have a lot of drive to keep sleeping past and EW, iyswim. Hopefully, it might get a bit better on its own once the teeth are through, but that's just something to keep in mind.
