I mean I am sure it's probably all crossed our minds at one point to open a mouth. My normal was choking on a repti-bark chip from his enclosure and I had to remove it but I definitely hate having to mess with their jaws. It's all they've got to defend their little selves. But in any case I am sure everything is fine with your ball. If anything an injured tooth, I would try to explain how to inspect for one but it's hard to type. Either Youtube how to check for a broken snake tooth- or something of that variant or a trip to the Vet. if you suspect an actual tooth injury.
I don't even know what I call what I use to inspect. I mean you could use a probe if you had one. Make sure it's clean ;P
Edit: And be careful.
