I think you get more than a tiny bit of recognition as an MD but oral surgeons don't get their MD for recognition. They get it partially so they can also admit patients to hospitals. You can't do that without an MD. When I shadowed the few oral surgeons there were way more things they did than just the basic wisdom tooth extractions and other difficult molars. Implant dentistry is definitely the way to go if you want to make the money and GP's are doing that these days in their offices. I saw things like broken jaw repairs, sinus augmentations, sinus lifts, stuff dealing with eye sockets, stuff with cheek bones, etc. I saw this girl that got in an accident and her face was pretty much indented inward....I didn't stay for the whole surgery but after hours of work, the end result looked amazing.
OMFS is a great specialty but if you're looking for the money go into endodontics or orthodontics. There's not nearly as much overhead you have to pay for as well as malpractice insurance is probably twice that in an OMFS office. Cosmetic dentistry is also on the rise and general dentists are doing more and more specialty work in their offices. Today, the dentist I shadowed put in 3 implants and a tunneling procedure!
