Teething again?

It's been a long time since a teething post! But interestingly I think Sasha's getting a new tooth. My clues:
One day while we were riding in the car, Sasha started whining. I asked her if she was hurting and she said yes. I asked her where, and she pointed to the molar area of her right cheek.
Also, she's been gnawing on her finger like crazy lately. All day and night, she's got a finger in her mouth and it's all pruned up.

I haven't stuck any of my fingers in her mouth to feel for any bumps. It would feel weird to do that now that she's like 2 and a half. She's got a lot of chompers in there now so that sounds dangerous!
