Can my power bank explode while charging?

I got this power bank almost 5 years ago and it’s working just fine I have dropped a few times but nothing happened but a few weeks ago someone threw it on the ground and the case opened a little bit but I put back since then I have been scared of using it I used for 10 min and it was fine but never charged it and I really need it noww so is it a possibility? Should i end myself and the charger? Its not rusted just dirty (:
