INJURY question, please give your opinion

OK, so I was doing my cage maintenance this morning and I found my female looking like this.. I'm not sure what caused it but the right side right around her second heat vent is slightly depressed (almost like an under bite) while the left side is normal. I am pretty sure it looks like she was forcefully rubbing her nose against the side of the cage as she hadn't looked like this until today. Any ideas? I hope it comes back to normal after a shed or two. Please let me know what you guys think, if i should be concerned and seek out medical help or if this should go back to normal after a shed or two. She doesn't seem affected, I was handling her and she was perfectly calm as always no hissing or aggression at all. Please let me know and give any advice you can!

Can you check she hasn't caught her lip on one of her teeth while doing it?

I am with Del. Looks like she rubbed and snagged a tooth... can you rub it or open her mouth without getting bit.. or get bit and do it anyway :)

Feed her a small meal... it'll pop back in place. Or grab her head, and pull her button lip until it comes lose, then let her go. . . easiest just to feed her though.

Thank you!!!!
