Try topically numbing her gums and after a short time see if she'll eat. A thing about teething is that it makes the mouth produce extra fluids, so her belly might be full from the extra fluids she is ingesting. Another thing to keep in mind is that the pain of teething does not stop once the teeth cut through the gums; it continues as the teeth grow out. So the pain can come and go for a while. As long as you keep her hydrated,(try a random bottle of Pedialyte just to be safe) you do not have to worry about her. It is true that when she's really hungry, she'll eat.
