Oh wow that's terrible. You must feel so awful for her, poor baby. She's the same age as my LOs, and I can't imagine something like that.
I once bit the end of my tongue clean off, when it was numb from dental work. It grew back, just fine, and quickly, too. I think it was only a few days before it was as good as new. So I'm sure she'll be okay.
Are you nursing her? I would bet that expressed milk from an open cup would be comfortable for her to sip, if nursing hurts too much, and breastmilk has naturally anti-infective properties that should help with infection. You could just hold the cup for her and let her take little sips.
And breastmilk ice cubes might be fun.
