I never got any of Indy's baby teeth, I think she swollowed them all.
At one point she had 8 canines, it looked very bizzare when she was laid on her back with her mouth open, but all her baby canines seemed rock solid right up to the point when they were just gone.
I wouldn't worry, it'll come out when it's ready and the tooth fairy will have to leave something extra special with it being the last one.
