teething baby help!

My baby has been drooling a lot, shoving his hand in his mouth non stop, grabs my hand and puts it in his mouth and bites down on it as well. I'm pretty sure he's teething even though I can't see or feel much of his teeth yet.. what did you ladies use for your teething babies to help them relieve the discomfort? I try giving him teething toys but he doesn't really care for them and goes back to his hand..any advice on dealing with a teething baby is appreciated!
