Charger prong can wiggle after being bumped. Dangerous?

Hi all,

I accidentally bumped into this charger and now the bottom prong in this picture can wiggle left to right (relative to this angle). I wanna say it moved about 10° from its original position and you can see the bunched up plastic from where it moved.

I bent it back into position and it's still very stiff... just wondering if it's still safe to use.

Thanks for your help!
