Slanted teeth but dentist said I’m ready to get my braces off. What can I do? (Photo)

so one of my front teeth started to slant and it was caused by the braces, and two of my other teeth as well. i feel as if my teeth were even better looking before the braces. The dentist told me i might be ready to get my braces off but i don’t agree. do you think that if i tell him he can fix it?
