Thanks for putting up your question on Just Answer.
This kind of an injury doesn't seem to be so serious. Moreover, the discolouration would happen only over a period of time. Also, the teeth haven't become mobile.
The bleeding is common, that is from the gums.
The pain is due to the concussion. I suggest you take her to a Pediatric Dentist for a X ray to confirm the extent of the injury. Also, a painkiller (in the form of a syrup) will help.
Hope this answers your question. Please leave a positive rating if my answer has helped you.
