Help Luna the rabbit

She's a very happy and playful little bunny, who unfortunately has a
dental issue, which requires emergency surgery.
Luna's molar teeth became too long and sharp causing her great pain
when she eats.

She also developed some gum infection, because she wasn't able to
chew her food.
She hasn't been eating properly for a few days now, I have to force-feed her with a critical care through a syringe.
She already lost some weight.

I went with her to a vet, she got antibiotics for the infection and a
medicine preventing GI stasis.
The vet told me she needed her molar teeth burred ASAP, as she could
develop wounds in her mouth and her current inability to eat might be
life threatening.

My heart breaks when I see her standing on her hind legs asking for
food, as she's hungry, but whenever I give her food, she struggles to eat it and just drops everything.
