Hi Math14320,
This is the internet, so take everyone's comments for what they are.
I am assuming you are serious, and I am assuming your are not yet in dental school, but have a knowledge about oral and maxillofacial surgery based on either someone you know or something you have read, perhaps here at SDN.
As an oral and maxillofacial surgeon, the only time that I interact with neurosurgeons are:
1. If I want to harvest a cranial bone graft, and then I will only do it if they are down the hall operating at the same time.
2. In cranio-maxillofacial trauma cases, where we only interact for a small amount of time.
3. When they bring their kids in to get their wisdom teeth removed.
I would say you need to decide either to go to medical school or to dental school at the outset.
Having said that, I wanted to be a cardiac surgeon when I started college. My dad (an OMS) had me work for him during the summers, and I worked at the hospital across the street, so I was able to see everything (cardiac, neuro, ortho, general, etc.).
I found what he did (OMS) was much more interesting, had more variety, and he wasn't down at the hospital at 10:00 p.m. dealing with complications. And the patients did not die after surgery.
So I changed to pre-dental my junior year of college. I have never looked back.
PM me if you want some nonjudgmental feedback.
BTW, did you know that 4 our of 3 people have a hard time with math?
