A question about Rubik's cube

I keep a Rubik's cube on hand as a way to pacify hyperactive children, but it's counterproductive: They get so caught up in the puzzle that I can't get them to focus on reading, or whatever it is they're supposed to be focusing on.

I had a very fidgety kid yesterday who wanted to "solve" the cube by peeling off the labels and rearranging them so the cube was solved. It got me thinking:

If I had allowed him to do this, would it have compromised the puzzle at all?

The combinations/permutations are in the quadrillions, I saw on YouTube. It would take a trillion years to make all of them at which point we'd all be dead anyway and there wouldn't be any light to see the colors. But: Assuming there is only one permutation that "solves" the cube, could I then make a few twists and still have the original puzzle? I would know it could be solved, and the quadrillion-something permutations would quickly reassert themselves.

Would it be the same as having a new cube from the factory?
