Dont use toothpaste … use regular cutting compound. toothpaste is abrasive, but you dont know how much, nor if it is equally distributed in size.

A cutting compound with an orbital polishing machine can help getting the disks back to working condition. Beware though, if the mirror side of the disk is damaged, the disk is lost.

Polishing a CD or DVD is a very delicate operation in any case. Without the appropriate hardware and method, you will kill the disk.
