Teething and baby is in pain

Hello, my baby turned 6 months on the 4th. I think she’s been teething because she been waking up often at night, is very fussy when trying to feed her, fussy in general and is crying alot more all day. Always chewing on everything and drooling a lot. I feel bad because I know she’s hurting and I try everything. I give her cold teething toys, cold wet cloths, and even cold fruit in a one of those pacifier things. But nothing seems to calm her. Anyone have any other remedies or anything that has worked for their babies? Thank you !
