Stress
According to urban myth, those in dentistry are more likely to commit suicide than those in any other profession. Is it true? Nope. Physicians have the highest rate of suicides among professionals, and psychiatrists commit suicide at the highest rate of all physicians.
That's a relief…kind of. Dentists do have stressful jobs. For one, their patients are rarely happy to see them. Secondly, people sometimes view dentists as sadists who can't wait for an opportunity to inflict pain.
Thirdly, it's difficult to own your own practice. A lot of people's lives are riding on the fact that you are a competent dentist. There are also all of the headaches of dealing with insurance companies to worry about. That said, if you don't mind people being a little wary around you and you enjoy challenges, dentistry won't be that stressful.
