Mouth sores

Please help my ball python has a huge mouth blister I poped it but its big I do not think its mouth rot but I believe it's from a rat bite can a rat bite a snake while in its mouth ?

You probably shouldn't pop an animals blister... a picture might help but it's possible it might need a vet, especially to prevent infection.

I didn't mean to pop it I was rubbing proxide on it and pressed to hard and it poped thanks for the info
