I was given some good advice on here about teething. Try using an old sock (or something similar), soaked in very cold water, or better still, stick it in the freezer for a while and let her chew this, whilst you are holding onto it (I've heard what labs or like with swallowing clothing). The coolness will cool down the sore gums and she will enjoy biting into the softness of the material. This worked a treat for me.
