Orthodontic problems are built into your genes.
Back, 10,000 years ago, in the days of the cave men people had nearly perfect bites. No one needed braces. But then adult cave men were only four feet tall. Teenagers were two or three feet tall.
In the last 10,000 years, people got bigger. People's mouths got a little bigger but people's teeth got A LOT BIGGER. The result is that most peoples teeth no longer fit correctly in most people's mouths. Your orthodontist moves around your teeth and possibly stretches your mouth so everything fits correctly.
Look how big your front teeth are now. Would those teeth fit if you were only two or three feet tall? Chances are, probably not.
