Do you have pics?
How long have you had him? Since birth? If not, what was he eating before you got him? Rabbits really should have at least a bit of vegetation from the time their old enough to nibble, they do best down the road with a variety of food when they're weaning. They will naturally eat what their mothers eat.
Toys never work around here, they only chew on cardboard boxes, toilet paper rolls with hay stuffed in them, and sometimes fruit tree branches. The best tooth-trimmer is natural vegetation like grass, weeds and vegetables that haven't had the fiber bred out of them. (Humans may prefer tender veggies, but it's not natural for rabbits).
If he does have a bad malocclusion, might be best to have them removed while he's still young, but I'd like to hear from more experienced people on whether it can/will correct itself.
