Welcome to the site!
Next time post this type of thread in the BP husbandry section, it will get more views that way.
I wouldn't be terribly worried yet, and there really isn't much you can do at this point anyway. Over the next few days to a week or so if you see any swelling in or around the mouth a trip to the vet might be necessary to get some antibiotics, but I don't think you are going to have any issues based on your description.
Maybe it's time to consider pre-killed or frozen/thawed rodents.
