3 month old great squirrel with only 2 incissors

I've had cherub since she was a day old. I raised her with puppy milk, like I have with all others I've hand raised. Last month I noticed she only had 2 incissors. 2 on top, one on the bottom. Yesterday I looked again and now she only has 2, 1 top 1 bottom. The top one is black. It she just getting her adult teeth or is this something different?

Grey squirrel, not great tho, she is great. :)

May have broken the teeth then had them become infected due to not having some out right after the break, is all I can think of. If the roots weren't also infected they might still grow back that can take many months though.
