Can I have my tooth/teeth filed to make them even/parallel? (Photo)

I've just had my braces taken off, I don't really think they're straight after 2 years, but mostly because of different sized teeth, especially my front one which is built up after I chipped it in half years ago. I wanted to know if I could have the central and lateral incisors on the right hand side filed down a little to make them look even, and your opinion on whether it would work ect.
