car bumper reinforcement bent a bit, bend back or replace??

the Mrs has bent the Mazda's bumper reinforcement bar behind the bumper a little bit after running into a concrete pole at moderate speed, just wondering what impact this would have on the safety of the vehicle if it was just bent back out?? would it weaken significantly the structure in the event of another incident you think?? or should I replace the reinforcement bar to maintain rigidity??
