That's it's egg tooth, which the turtle uses to break out of the egg. It's not the egg tooth, but the egg sac (located in the center around the lower third of the plastron) that provided nutrients for a newly hatched turtle (and will do so for longer than many people think). Don't remove the egg sac if your turtle has one, and don't let it dry out and fall off---let it disappear naturally.
When my painteds came of their nest, all had egg teeth. The time it took to lose them varied--some within a week, some after a few weeks.
Good luck with your babies.
