Usually, the teeth fall off the same order that they came in. Usually, they lose their first teeth between 6-9. Although she’s definitely in the later side of the tooth loss process, I would not worry too much yet. However, if you do have any concerns, I would take her to a dentist where they can take some X-rays to see where the adult teeth are lying and how much longer the baby teeth will be there.
I hope this answers your questions.
