Bonding disaster - what can I do? (Photo)

I had bonding done and it’s ruined my life. I had a beautiful smile that I loved but let a dentist talk me into bonding my teeth and I hate it. I’ve had it redone multiple times and it’s still awful. It looks fake and there’s black lines and gaps between my teeth. What causes these black lines? In person it doesn’t look that bad but in photos it’s horrible. I used to love pictures and now I avoid them at all costs. What can I do?
