| Dear dlk,
Welcome to the forum!
As a rule, damaged plant tissue does not regenerate or "heal" like human tissue does, but that does not necessarily mean those roots are dead and gone. if you have new root growth that's good. Let them grow. Learn from the incident and don't let the roots get exposed like that again.
It would help us to give you more useful advice of you could post a picture of your orchid, plant, flower, or whatever you have so we can at least identify what type of orchid it is.
Cheers
