yup, we just got a bunch of teeth here too, ouch. seems like sometimes it hurts, other times it doesn't. Yesterday I noticed that if I supported my breast it felt better (and I don't remember it being an issue with my first one). I would say that if it doesn't feel right, try relatching to see if that helps, adjust baby or the breast, or your body and try to figure out what is most comfortable. Maybe even a different position?? Its just about finding a way where it doen't rub the wrong way.
