I had this happen with a large hogg island boa about 12 years ago. I was trying to spot clean her enclosure but she apparently wasnt accepting visitors. She only ever bit me once and it was pretty hard. I am usually really good at not jerking away when I get bit but I jerked pretty hard that time. When I looked back down at her her lower jaw was curled down about 90 degrees and upper about 30 degrees. I freaked out and took her to the vet. He literally rolled her mouth back into shape. He said as long as she acts fairly normal and takes her next meal with no difficulty she should be fine. She never acted weird and she took her meals perfectly.

I'm not saying that you shouldn't go see a vet. It will most likely set your mind at ease. Snakes have pretty flexible jaws. Hopefully it doesnt end up to be too serious.

Good Luck!
