Swollen face after tooth extraction?

[ihartgonzo]

Fozzie just got his upper right molar pulled on Friday. I noticed yesterday that his muzzle was all swollen on the right side. I looked at his incision, it looks totally fine and his mouth isn't swollen at all. It's like his nasal cavity is swollen, and his nose is a little runny.

The Vet told me his nose might run, as that tooth is connected to the nasal cavity. But I didn't think it would swell up like this. I'm bringing him in tomorrow to get looked at. Has anyone else noticed this after molar extractions?
