|The lower right tooth (our right, his left) is out of position and discolored.|
Still, I took him in to see the vet. Vet says there's likely a little bit of infection in there. Sometimes teeth that get loose like this come out on their own, but the incisors have very long roots and it seems unlikely that this one will pop out on its own. So we can either treat for a mild infection and just monitor the tooth, or we can schedule anaesthesia and do an extraction and do all the follow-up care on that. I opted for antibiotics for 2 weeks and just keep an eye on the tooth. There's no puffiness or lumps at the site and no reaction at all when we wiggle the tooth.
Jeez, I'd hate to have a toothless old dog in my care. Vet says his other teeth look fine, though.
