Oh wow, poor girl. No wonder she wasn't herself. Abcesses hurt pretty bad, esp. in the mouth.
If there is so much as a TINY piece of infectious tissue left behind, there will never be 100% healing. It will always blow right back up after antibiotics. This is the best thing you could have done for her. Have her "out" so that a vet can go deep, take out every bit of diseased tissue and matter, irrigate and rinse very well and then insert antibiotic wash into the wound. That plus some antibiotic shots should finally allow true healing to happen.
I bet she already feels so much better. The pressure and pain of an abscess can be excruciating and who knows, it might have been part of why she kept smashing her face. I've had other animals mutilate themselves because they messed with a painful part of their body. They do not comprehend that it only makes it worse.
I hope she will turn the corner for you now and you will pick up a healthy and happy Retic girl, to enjoy her new and large enclosure. You sure have been through the wringer with this girl, you both deserve a break!
