Buster developed a bump on his face a few days ago. It's on his cheekbone. I assumed that he bumped his face on something, but it persisted for a few days, so off to the vet he went.
The vet thinks he has an abscessed tooth, so he was put on a course of antibiotics. While that will probably take care of the current problem, the abscess is likely to recur, in which case he'd need to have the tooth extracted. It never ends.
