Please take with a grain of salt. This is just my own experience and I can't really vouch how other new grad dentists's experiences were. Long story short: I love it. I can utilize specialists around whenever I have a procedure I don't feel comfortable doing or I don't want to ( e.g. Max Molar root canals) and still able to make decent living. I was at the verge of losing my morality as a dentist when I was working in metropolitan area, since if I don't produce , less opportunity to grow financially.I haven' done any unethical procedures but I was getting very tempted. Now I can do treatment plans without any peer pressure and I feel I can practice dentistry ethically. I am a homebody, don't like to go out, and the area needs to be quiet to sleep. And I am saving a lot on rent. My office is almost FFS ( we only accept one insurance). Having said that, if you do accept something like HMOs or medical insurances for dental by comparing procedure to procedure, you would be making less money. It's hard for me to give you a set answer to your question. It depends on the demographics, socioeconomic status of your patients,etc. Some people think rural = more $$ , but unfortunately, that's not always the case.
I am married, so the first option is no go for me at the moment. I know classmates that can pay student loans and save at the time. I can't at the moment. I am doing minimum payment on my student loans and trying to lower other loans ( car, credit cards) as of now. Everyone has different financial situations. I will soon write a new post regarding my experience so far as new grad dentist. In regards to opportunities... I would say it's all about luck. If I really looked, I probably could have found an opportunity similar to current one, except COL would be much higher.
