Try cooled steamed julianned carrots to chew on, or anything cold for her mouth to munch on.

There's a gel, SM-33 that's just wonderful, it has an anesthetic in it (pharmacy only) similar to throat lozenges. Bonjela has aspirin in it I think? Best apply to a cooled teething toy...

I do know for myself I chew on cloves, but I don't know how to translate that to a baby.
