My fiance's father is a dentist in Philly, and he and his colleagues have been sued several times each. he hasn't lost a filed suit yet, but it's still a pain in the butt. if one is trying to escape frivolous suits, joining the rastafarian brigade would be a good option- seems to be the safest sect. Seems everyone is fair game for lawsuits these days, even God apparently, who was sued by Senator Chambers.
more than anything, is the economic opportunity in dentistry that is broadcasted well... everywhere. More dentists exiting than entering - shortage in supply = economic opportunity. That's the general trend in other markets, so I doubt dentistry is any different. I've met a good number of people who want to enter community work, but I've met even more people who are simply in it for the money. Dilutes the humanistic aspect of it all, but it's hard to stop that train when people see green.
