I don't have direct experience with impaction but, from what I've read, the snake has to consume a fair bit of substrate for it to be really dangerous. I can't say I know what a "fair bit" would be but I'm pretty sure that a few stray pieces aren't dangerous.

I've never read about mouth infection but it sounds reasonable. Unless you want to run to the vet for every little thing (which you might) you have to make an educated guess about the danger level. I suppose if the thing really got wedged in there the chance of infection might be significant.
