Oh, welcome to you and Juliet and thank you so for rescuing her. Bless her little heart. Just give her space and time to settle in and get to know your place and you. Let her come to you and make the advances and most of all, and I know this will be hard, be matter of fact in your dealings with her. Being sorry for her and petting her when she's very scared won't help her but just being there for her to distract her a bit with a bit of a treat or tossing a ball will work help redirect her energy toward the new thing instead of her fear of what's going to happen.
She sounds like nobody took a lot of care with her little teeth to brush them and such so she probably lived with someone who wasn't too dog- or Yorkie-savvy, as Yorkies often have very poor dentition, get gum disease and caries so easy. They also can have quite a few stomach problems and rich, greasy foods can really cause them issues if they are one of those types. For 5 years Tibbe wasn't but now he does have an iffy tummy and has to eat prescription food.
Again, thank you for helping this little lady and I know one day soon she will grow into your very best friend.
