I have straight teeth. I chipped both my top front teeth a bit when I was little so they are a bit shorter than I’d like. I don’t want to change anything other than fix the 2 teeth. And I don’t want to put Veneers as I don’t want to shave my teeth down. Can I put Lumineers only on the front 2 teeth? Or will I need to put on the neighboring teeth as well. Will the color match? Do Lunineers come in shades?
