So what's the problem now exactly I did't understand.which aspect of the treatment are u not satisfied with. It is routine for dentists to give a retainer post orthodontic treatment to avoid a relapse. A lingual wire does not mean u don't wear the retainer you still should wear the retainers for atleast a year post treatment. If the esthetics is stopping you , you can get an essix retainer which is transparent and almost invisible

Well if you are not satisfied then consult another dentist.try a specialist orthodontist
