Fine with the teeth. Yes in post flood days we had a more vigourous diet of meat.
Our bodies are fine. I don't know the actual original body of Adam and so some changes may be in order.

For example originaly women were not to have birthpain . However God gave Eve the punishment of birthpain, which female animals don't have, and since this pain comes from womens unique body shape then we must conclude there bodies were changed at the fall.
Still sexy but might of even been better.
