Abscess/infection in mouth?

[AmateurRehaber]

I have three 7 week old grey squirrels who are doing pretty well overall, but my male(Rikki) has a lump on his chin and right cheek. The lump is firm to the touch and a little pink under his fur, I had read that infected cuts can have a similar affect, this is the second place I've looked for help, I want to reduce the swelling and any pain he's on asap. It's illegal to have squirrels as pets where I live but will take him to the exotics vet if I can't help him or this is something that won't clear up on it's own.
Thanks to any help/advice

If you could post a photo of the possible abscess , that would be really helpful. Also, can you check on his teeth and make sure they look normal (not overgrown/too long or wonky looking)? Thanks.
