Is there a particular reason you don't want to just feed her back to sleep? Sorry I can't help with what to do as I have always just fed mine back to sleep whenever she wakes as that means she goes straight back off, and I can get on with whatever I was doing (planning and marking by the time she was 6 months). She started sleeping through at just over a year, but we'd just been awake once or twice each night for a few months before that. And the teeth thing can make a massive difference to night time sleep. During the day she is distracted by other things but at night all she has is the teething pain. I assume you are breastfeeding (don't shout at me if you aren't - just something makes me assume you are) and babies get a lot more than nutrition from breastfeeding, it's a pain reliever and a comfort all wrapped up in one handy bundle. For what it's worth I would just feed her til her teeth come through and then reassess whether or not it's easier to stick with that or change something.
