Oh how I don't miss those crocodile teeth! This is pretty normal behaviour, according to my experience. All you can do is try and stop it and give them something else to chew on other than you but it takes alot of perserverence. We had Bella absolutely obsessed with hanging off our sleeves and trouser legs for weeks and she then moved onto chewing hair and launching herself at your nose (ouch!).
It will pass but probably not for some time yet, so just protect yourself as best you can and discourage her as much as you can. You can try spraying your hands in that anti-chew stuff - this didn't really work for Bella but might be worth a go.
Bella now has her adult teeth but because one of her canines is in the wrong position (just starting to stick into the roof of her mouth and she's off to the dentist for a doggie brace next week!) she is still really mouthy as it's more comfortable for her to have things in her mouth all the time - blunter teeth but much stronger jaws, so she is still mrs crocodile...
She can REALLY snap like a crocodile now, sometimes just lies on her back going snap, snap, snap! I sing a Tori Amos song to her, "hello Mr Zebra, ran into some confusion with a Mrs Crocodile-dile-dile".
