Wow! She lost a whole bunch at one time! Poor thing, I'm sure it's no fun to eat right now!
For the time being, maybe try adding some water to her food if she's having a hard time chewing it. Or you could try canned food (but they love it so much it's hard to get them to go back to dry food after that!).
She should be getting new teeth in really soon. With Miles, it seemed like it happened over night! Good luck!
