Given teeth are done and no pain... You have to introduce to the bit nicely and gentle. You never want to drug it out when you are done, you never want to push it in. Just stand quietly on side and ask her to take bit in. If no response, stick your finger (gently!) in corner of the mouth asking to open a mouth and again slowly and gently put the bit in looking not to hit horse's teeth. Then proceed with the rest of the bridle.
