Is contouring/shaping advisable for buck teeth/overbite? Or would invisalign/metal braces be a better option? (photos)

I have uneven teeth with two front buck tooth. I am very self consious about the appearance of my teeth when i smile. Is it better to contour/reshape and file down my front teeth or is it better to go straight to braces or invisilign? Which one would be a better option for me. Any clinic recommendation and suggestions would be higly appreciated. Im located at scarborough ON canada. I am in college and 18 yrs old with regular 3 month cleaning and never had brace. Thanks so much for your help!
