Because he is suffered a lot while treatment.
Thanks for your query, I have gone through your query. The teeth should be aligned properly at the end of the orthodontic treatment. So if it is not aligned properly, since you are telling it is almost 2 and half year duration, better to consult a good orthodontist and take an opinion. If there are minor corrections, that can be corrected. If it is a major correction, then it has to be redone. I hope my answer will help you, take care.
