Flexible
scheduling is a distinctive feature of this job. Full-time, part-time,
evening, and weekend schedules are widely available. Dentists frequently
hire hygienists to work only 2 or 3 days a week, so hygienists may hold jobs
in more than one dental office. More than half of all dental hygienists
worked part time—less than 35 hours a week.
