First, I'd like to thank all of your for your comments of support. I can't express how much you guys mean to me; no one around here understands the love and dedication a person can feel for a rabbit so having a network of support like this community helps a lot.
Bella survived the anesthesia. The vet has called Oklahoma University to try to get a better recommendation on how to proceed. The x-ray discovered that her entire bottom jaw is calcified and her teeth are broken at the base, inside of her jaw. I have never felt so infinitely depressed and furious simultaneously before. This could have been taken care of the very first time I took her in for the abscess, but none of the vets she saw bothered to check the cause; they'd simply lance her and send her home. By the sounds of it, she has had this bone infection for a very long time and the vet is basically telling me that proceeding with any treatment is risky. I will not be accepting that as an answer. I will find someone who can help her, I don't care if I have to leave the country to do so, but I am not willing to give up on her until I have tried everywhere and everything.
