Post braces marks - micro abrasion

[Post braces marks]

Hi everyone,
I had braces for over two years and after their removal, I was left with the yellow marks on my teeth. I went to dentist to had my teeth polished, air flow etc. but nothing works. Someone mentioned to me dental micro abrasion - has anyone had it done?

Is there anything else that I could try? I don't want veneers - I have healthy strong teeth.

Thanks in advance for any advise!
