Sorry no one responded to this for so long!
Hmmmm, seeing the title I was going to say prob a dental issue… then reading the post I see that’s exactly what it is!
Is it possible that part of the tooth is still there?
It might be good for the vet to do an x-ray to see if there is anything going on with his molar roots that they can’t see. Especially since you say he’s still not 100% better with his eating. I do think the vet could be right though, molar extractions can be tricky.
I suppose it’s also possible that he has an infection that isn’t treated by Baytril. Dental abscesses usually need penicillin injections, so I wonder if he might need a different antibiotic? Or could have a dental infection that isn’t visible?
Assuming that his teeth are in fact all OK (and it isn’t some underlying problem), then I don’t think the weeping should cause too much discomfort (but I don’t have any personal experience with this). You can wipe his face with a warm soft cloth daily to keep him clean. I’ve seen bunnies with tear duct issues as they get older, and it doesn’t seem to both them too much.
