*shakes fist at desi dentist that doesn't answer a simple question*
Well its bad for him, because his pocket money won't grow, when he'll send you a bill for extractions of those four teeth. overall its good for you. If you've a small jaw to begin with, by additional teeth in your mouth your wisdom teeth might push your other teeth and cause 'crowding' which isnt great. then its a pain in the neck, you see.
correct me, if im wrong, budmano786, displaced.
