Is there a way to fix a slightly bend slider rail on the tablet?

So the switch I have got a bit of a dent in the plastic since it got hit, and it messed up the top position of the right slider rail for the joy-con so I can't insert it there anymore, is there a way to fix it to position or melt the metal since I've tried fixing it with some pliers which didn't work by the way, so there's a way I can re-insert the joy con again without sending it for repair?
