She's fine now, the wrinkles in her skin was caused by the shed and not dehydration (I gave her a soak anyway just to be on the safe side), she's not having a bad shed and is shedding just fine.
I'm thinking of switching her substrate after this shed. She hasn't gotten any more of it in her mouth but then again I don't want it happening to her a second time. I'll try out the reptibark and see if its a good fit for her.You might want to look into switching to Reptibark substrate. My snake had the same issue with dirt in his mouth once before. I was using coco substrate in his tank and putting down a paper towel for him to feed on. He moved his mouse off the towel and got a huge mouth full of dirt. I had to remove as much as I could while he ate. I switched over to reptibark the next day and never had another issue. It’s easier to spot clean and maintain humidity with as well. Just something to think about.
