About 2 years ago I finished orthodontic treatment to have my congenitally missing maxillary lateral incisors replaced by my canines and had two of my bottom premolars extracted to have this done. I have since been unhappy with the results and feel like I have had a change in facial shape for the worse (however I am unsure whether this is due to the braces or not). I was wondering if there is any way to undo this treatment in the future so my teeth are where they are meant to be, to replace my missing teeth with implants and whether or not this could improve the shape of my face. I was also wondering if you could estimate how much this would cost as I assume I could not get braces on the NHS again.

Thank you,
