Her mouth will grow a lot between now and when she gets her adult teeth so her teeth will actually be moving constantly between now and when the adult ones come through. There really isn't anything that will indicate if it will affect the adult teeth when they do eventually come in - and they may come in crooked and straighten up as the others come in too.

There is nothing a dentist can do until she is approx 12yo (remember all the teenagers are the ones with braces) so try not to worry as it is out of your control and nothing you can do about it anyway for a good 10 years or so and who knows what they will be like by then.
