That's really good news that the thrush seems to have cleared. Pity about the teeth!! Biting is usually a temporary thing as they adjust to the new sensation of teeth in their mouth. Paying careful attention to positioning again can really help, and some mums find it helps to give them something cold to chew on just before a feed. If you do get bitten, sometimes it can help to give your DD's head a gentle push into your breast - this way she is unable to bite anymore, and it's unpleasant for her so can deter future biting. There are some other ideas here - Australian Breastfeeding Association - Biting and Breastfeeding.

Best of luck!
