Can an orthodontist fix my uneven smile? (Photo)

You have  very narrow maxilla (upper jaw) and while orthodontics can straighten your teeth it will not correct the real problem.  Your smile is really only 6 teeth and ideally a full wide beautiful smile is 10-12 teeth.  you have black buccal corridors and virtually no display of your back teeth.
The underdeveloped maxilla does not support the soft tissues of your face giving you deep nasal labial grooves.  The DNA Appliance utilizes Epigenetic Orthodontics/ orthopedics  to expand your maxilla three dimensionally.  In addition it will expand your airway thru a process called Pneumopedics.  Widening the upper usually allows the lower jaw to move forward improving your profile as well.

Hi:From the photo it appears that you are a very good canidate for orthodontic treatment to correct the asymethry of your smile.  Ultimately a complete clinical exam, X-rays and models is necessary to diagnose and give you the correct option.  Best,Dr. Maddahi
