What makes the nose become awry?

i feel uncomfortable about my nose.i noticed that it becomes awry, my nose is not that pointed,not at all but still i notice that it somehow became crooked although my nose bridge is not that prominent. i happen to think maybe its because of my teeth?is it possible? i think the teeth has a big part on the facial shape.and i just noticed this when i had my 2 upper teeth removed.is it really possible? iwant to have my teeth braced but when i remember all the people i know who had braces,they somehow loss their brilliant smile and it only made their apperance worse.
