Do you have any syringe feed you can use if she refuses food totally?
I just bought more today and have spare, I can give it to you on sat for future if you want?
I'd just povide her with lots of different things to eat overnight, get to vets in the am.
Get teeth checked, and ask for some emeprid for you to keep in the house in case of times like these, I also have a bottle of metacam as well.
They come in handy.
Obviously if she changes during the night, and you become really worried then it's a taxi to the emergency vet.
