I'm 25 years old and have an underbite. Do I need jaw surgery or will braces fix it? (photos)

You have an underrdeveloped maxilla.  I strongly suggest beginning treating with Epigenetic orthopedics.   The DNA Appliance can grow your maxilla and your airway.  There may be a functional shift component where you jaw came forward as an adaptation for a small airway.Three dimensional growth is the perfect way to begin treatment.

HI, thanks for sending your question and pictures. Although some providers may suggest surgery as it can be an option, we can use alternative methods to correct your bite without surgery. Clear invisible orthodontics can be used without the use of old fashioned braces to help you. Feel free to come to our Shermna Oaks office for a private complimentary consultation. I am confident your smile will look great! All the best.
