There is no single job out there that would be best for every person in the workforce. But many of the best professions do have some attributes in common.

A few of those commonalities: they pay well, challenge us over time, complement our talents and skills, aren't too stressful, offer room for advancement throughout our careers and offer a positive work-life balance. Whether or not the position is in demand by job seekers is also a consideration in selection.

The job of dentist moved from No. 4 to No. 2 in U.S. News & World Report’s annual rankings of the 100 Best Jobs, the magazine revealed on its website on Jan. 7.

For the third year in a row, software developer topped the list as the best job overall. After that, all the top spots went to professions in the healthcare arena.

Dentist — which topped the list in 2017 — moved up from the No. 4 position last year. Physician assistant secured the No. 3 slot, followed by orthodontist at No. 4. Oral and maxillofacial surgeons rank No. 9, with healthcare occupations tallying 46 of the 100 best job spots, according to the magazine. The magazine’s news release on the topic stated that occupations in healthcare continue to show promise due to a combination of high salaries and low unemployment rates.

Whitney Blair Wyckoff is a senior editor at U.S. News & World Report. "The world has evolved significantly over the last ten years with how we use and depend on technology,” she said. “So for students who love math and science, we have good news. Our 2020 U.S. News Best Jobs rankings is packed with health care, business and technology occupations. Though you may need a lot of schooling before you get your first job, many of these roles come with high salaries."

U.S. News & World Report gathered data on nearly 200 jobs from the federal Bureau of Labor Statistics and conducted some of its own reporting to come up with the Best Jobs of 2020. The magazine considers factors such as median salary, job growth over time, desirability and the opportunity to maintain a favorable work-life balance.

The Bureau of Labor Statistics has projected 7.6% employment growth for dentists between 2018 and 2028. In that period, an estimated 10,400 jobs should open up for dental school graduates.

The magazine also highlighted the Best-Paying Jobs, with oral and maxillofacial surgeons ranking No. 3 and Anesthesiologists topping the list. Dentists made a median salary of $151,850 in 2018, the report said. The best-paid 25% of dentists made $208,000 that year, while the lowest-paid 25% made $107,440.

The publication only highlighted what dental professionals already know. Dentistry is a rewarding, fulfilling career path with many opportunities for growth.
