Help With Macbook Disk Drive and Loading Disks?

When I put a disk into my mac (any type of disk), it doesn't go in properly, it kind of gets stuck, and then if I push it, it goes in, but doesn't make a whirring noise, or eject it. It doesn't register it on the screen. If I try to eject it, nothing happens, and the other day I had to pull the disk out with a pair of tweezers. I have tried many different types of disks, but nothing will work! Can I get any help? Preferably safe solutions, because my mum won't be very happy if I trash an expensive laptop! Does the disk drive need to be replaced?
