- For a 35-hour workweek, orthodontists earn a median $350,000 a year, according to the Journal of Clinical Orthodontics. General dentists, meanwhile, earn about half as much working 39 hours a week on average, in a much dirtier job.    
- The difference in their training isn't like that of a heart surgeon vs. a family-practice doctor. It's a mere two years, and a vastly rewarding investment if you're among the chosen: U.S. dental schools have long been criticized for keeping orthodontists in artificially low supply to keep their income up.    
- This isn't brain surgery: Orthodontists simply manipulate teeth in a growing child's mouth  and often leave adjustment work to assistants whose handiwork they merely sign off on.
