Chronic Mouth Swelling - need advice

[Daybreaker]

I know swelling can be irritation from a feeding that scratched or bit the inside mouth. And or the teeth coming out of the gum lining causing abscess to form.

Her last meal was November 6th - a F/T rat so don't think it was from that.

A broken/ripped out tooth however is my #1 guess as to her problem, it's just so hard to say though
