A bitter question of trust

I had a lot of bad experiences with bad but mercantile dentists throughout my life but I wasn't conceiving that something like this will happen to me also in the US, the country of million lawsuits and malpractice legal procedures. I guess the only thing left to do is to act like a Roman (while in Rome) and drop a seed of suit on this bad dentist to recuperate at least a small part of my loss in a monetary form.
Because of him and his actions, I had to leave everything behind, put my research and life on hold and fly back to Romania and get the problem fixed right away, since it is quite serious and it could get easily very ugly. But again, the sad question remains unrelated to money (although I had to spend/lose a lot to do the things described above) but to trust and incentives. Does it have to be all about money? We want to become doctors nowadays to get more financial gains out of it, while disregarding the patients statuses and running the bills on them, or it should be a question of compatibility and desire to help other human beings? If you put it like this, the answer is obvious. However, reality is not. The imperfect information that the supply of health market enjoys it is hard to set-up rules that will protect the customers without involving such big social losses that intermediaries such lawyers enjoy, which ultimately do us all a negative favor by pushing the prices up as a buffer for all these doctors on which to land on when the shhht hits the fan.
In the end it's just a sad question of trust in your doctor, especially for those who don't do their homework (goggle-ing or asking around before they decide for some intervention) and information (why we don't have a ranking system or a GPA posting for doctors?) out of which each one gets out as he or she best knows how.
