I'd recommended removing the water bowl because OP was worried about his snake ingesting substrate. I gave mine a dry mouse and he dragged it through his water and then of course all the bedding stuck to it, so I suggested if he was worried to take the water dish out and offer a dry mouse.
I'd listen to the other advise about assisting, and wait. That's one area I don't know tons about. Like I said I usually see it as a true last resort option, and I don't think you're there yet![]()
