Blackberry Pearl

How can I fix my Blackberry Pearl Flip removed first screen?
I was with my friends today and my Blackberry Pearl Flip fell out of my pocket. The top screen is much younger than the scratches, but some are larger than the inside of my phone displays. I'm quite scared. I do not know how my father! Please help! How do I fix these scratches? Remember, you are in the screen black on a BlackBerry Pearl Flip I fear that white toothpaste will not help.
