Help ! Baby teething early

Has anyone's baby started teething early? Mine is 2 months old and for the past few weeks he's been fussy/crying all the time I didn't know what the heck was wrong but I started noticing he's been drooling alot and biting on his hands. I looked at his bottom gums and there a white thing, I felt it and it's hard. Anyone have any remedies to help soothe him I feel so bad. I thought I had more time until this would happen.
