Future job

I'm studying general dentistry, but I want to have a major in Maxillofacial surgery because I have a muscular problem since more than 4 years ago and I went to a lot of specialists but nobody helped me to fix my condition until last year, my parents had to spend a lot of money on the doctors, the travel and also the place we were staying.  I'm not from Santiago so that's why it is hard to find a good specialist in my city (practically impossible) and I want to help the people that is from regions like me so that they don't have to suffer needlessly and have bad or sometimes not having medical attention.

 I imagine working during 8 hours and sometimes maybe have emergency calls but not too often. So for that I would have to study 3 years more after having the general dentistry title. I would work indoors, but I think I can travel too, maybe doing courses on other countries, participating on investigation and that kind of things. I also think the salary is going to be good that I can live with anything I need.
