So I just checked on my big girl and I noticed this. She doesn't like being held firmly so trying to get her to hold still was next to impossible. I don't see any blood and it hasn't affected her appetite (though nothing does), but it does look as if the tooth is coming out through her upper lip, at least from what I could see. We have a good vet nearby but I don't know if this is something that will just go away on it's own or if it requires a vet visit. Have any of you guys had this happen? Or should I just schedule a vet visit?
