What is this?

I don't know what this is. It showed up a couple days ago. I knwo I shouldn't be worried, but her lower tooth is making a black hole in her gum. I just want to know if it could be dangerous and cause her gums to bleed or soemthing? :(

I'm not sure what that could be, if it does get worse though I'd get it checked out by her Vet. I've never seen anything like it before...

i would just call and ask your vet- just to make sure.
