Sure, dental hygienists assist dentists with teeth cleaning. But today, a host of career opportunities exists outside the dentist’s office ? from helming research studies and teaching to working for manufacturers of cutting-edge dental equipment. And it’s not just the job description that’s expanding: The number of jobs for dental hygienists is expected to grow 38 percent to more than 250, 000 jobs from 2010 to 2020. The job requires a two-year associate degree, but a four-year bachelor’s degree will open more doors professionally. Students must then sit for a national licensing exam and several state-level licensing and certification exams (varies).
