If you’re trying to decide between ortho and OMFS, the answer probably isn’t OMFS.
Reality is that to get through OMFS residency, you have to love it enough that you’re okay doing it at odd, unusual, and cruel hours. Otherwise, it’s a real meat grinder for 4 years. You have to be able to get excited about starting a trauma case at 9pm. You have to be stoked to run in and close a laceration at 2am. You have to tolerate getting out of bed and coming in to preround and deliver a crisp presentation to a senior resident at 6am.
After residency, you do what you want, but money generally isn’t the primary goal. A few people chase the money via perpetual exodontia, but come on, no one ever who’s willing to work ever goes broke in general dentistry, orthodontics, or OMFS.
