Teething remedies ?!

Aleksandra
My 3mo has been teething since she's 2mo but now it's bad, she gnaws at her hands And mine. Hates teething rings, I give Tylenol but it seems to have stopped working already. I tried wet washcloth, works for about 2 seconds. She's so cranky and wants to sleep but doesn't. Idk what else to do.
