How does our body know the pattern to regenerate a finger print and how much damage has to be done to disturb the pattern regeneration?

Question

I got a decent cut in my finger the other day. By today it has healed itself completely and the pattern looks undistrurbed. My question is, how does our body know the pattern to regenerate and how much damage has to be done to disturb the pattern regeneration?

The DNA, the stuff that decides what your fingerprints are from conception, makes sure they heal the same as they were, but it’s never 100% accurate. That said, the only way to make a finger print unrecognizable in a scan would be to slice, burn, or dissolve your fingertips off.
