Sabka Dentist — Wrong shape of crown

I had braces 2 years ago that time i came to know i will have to perform root canal treatment...so the doctors decided once the braces treatment is done they will finalize a crown on the front teeth which was performed root canal. Now when the braces treatment is over and time for the permanent cap they ruined it ...the cap wasn't made perfectly of the shape of the teeth and now the teeth are not aligned anymore...this the wastage of the 2 years treatment.
