PCB traces are damaged. Can it be repaired?

Hello to whomever reads this. I noticed while I was soldering that some of the traces look scratched out. It looked like white scrape marks on some of the traces. Does anyone know if there’s a legitimate way to repair the traces on a PCB? Or are the traces just past the point of being repaired if that happens?

Maybe I didn’t get your point.
A broken trace is mostly repairable by adding a jumperwire and bypassing the damaged part of the trace.
