I have crowded teeth and I am really self-conscious about my smile. What Can I Do About my Teeth? (photo)

Basically I have crowded teeth, I am really self-conscious about my smile. My two front teeth are overlapping, there just ugly to me. I take really good care of my teeth, and I cant afford braces which is fine because my two front teeth are the ones that bother me. I was wondering if my dentist could maybe shave some enamel off to give them a better shape? Is there something they can do to fix my two front teeth without braces? I also have Molina insurance. Thank you
