Nothing has seemed to work, we are just waiting, she likes to chew on hard things not anything cold so could try that. Washcloth we did before but still didn't like it, I even chewed on one but she didn't like the cold. Teething tablets worked on the other teeth but not these ones ugg! With the the tylenol recalls out there, we stopped using that, we let her fight the fever for a bit then use tylenol its good to let their body fight it off. I know others disagree just stating what I think.
I agree with the other moms lot of snuggles with mom sometimes she ends up in bed with us due to her not being able to settle down then when she goes to sleep back to the crib she goes.
Good luck I hope our teething ends soon too!
