Congrats!
I chose to specialize in OMFS mostly because of three reasons.
1) I saw a lot of general restorative work failing (crowns, fillings, etc) and didn't want to have to see my work fail. I had difficulty when I had to tell patients that their crown needed to be redone, and it overwhelmed me with regret. When you take out teeth, the teeth are gone. There are accepted complications, and sometimes that happens, but you won't ever have to take out that tooth again. Implants, have great success rates as well, 90%+ after 5 years, and generally if they last 5 years they're going to last a long time. The ADA says the average lifespan of a crown is 5 years if I remember correctly, and a filling is 1 year? Ludacris. Okay, the bigger OMFS surgeries like orthognathics can have significant relapse rates, but I think people understand that these are much more complex procedures that carry a lot of risk, and the risk of relapse.
2) I like that OMFS isn't primary care... We get referred specific problems, and we can do things to fix those problems.... often quickly and immediately. Then we send the patients on their way, back to someone else to coordinate the care for their other 15 problems in their mouth. As tertiary care, we also are the last stop for a patient's care - as a general dentist you are held to the standards of a much better trained OMFS every time you do an oral surgery procedure... I don't know about you, but that would cause me to have a lot of anxiety.
3) I appreciated the medical work-up and management of medically complex patients. I always had a lot of questions about patient's medical histories and realized in dental school that I was really interested in the pathophysiology and my dental school curriculum didn't do enough to explain it all. Medical school has been a good place to learn all this.
...I also dreamed about working 3 days a week, and OMFS seemed like the best way to do that.
... .... Also, my tinder account gets a lot more matches when I say I'm an oral and facial surgeon, and that I fix faces for a living.
