She will be fine. My Bella got spayed about two months ago. She was groggy when I first brought her home. She just wanted to be by me and sleep, she drooled a lot due to the anesthesia. Just stay by her side. Make sure she doesn't run or jump (which is hard to do). She'll be back to normal in a few days.
The teeth pulling won't hurt either. Mine had some of her teeth pulled,I believe about 5 or 6. I saved them, actually
