What options are there to fixing my large lateral and central incisors/flared top teeth after ortho treatment? (photos)

After braces, my central and lateral incisors still flared out. The Dr. who treated me said that is as far back as my incisors will go. I was also given plastic retainers which broke less than a year, my gap came back the next day. You can see how my teeth are shifting forward, and the space between my canines & lateral incisors is where I had extractions. Should I try braces again to pull my front teeth back? Also, Would veneers fix the appearance of my lateral incisors as well as my gap?
