How can I sharpen my teeth?

I heard it would work it u'd try the type of machines the use of shaping nails... in particular the manicure set of small handy machines of shaping nails... maybe u can find something in the female section of cosmetics... that should do... and the nail file could be dangerous if u felt a little pinch or pain lets say... in ur tooth.. .that would be the nerve calling out for help ....
