When replacing screws in soft material, I slowly turn them to the left to feel when they drop into the existing thread rather than making new grooves. And in my experience, IKEA furniture reassembles fine multiple times. You also have to make sure such screws are and remain tight, because if they start getting loose that working back and forth will destroy the threads of the softer material. If a piece of furniture isn't solid, figure out why and shore it up before it gets progressively worse.
