Day in the life
A Day in the Life of a Dental Assistant
What dental assistants actually do from the start of a shift to the end: the tasks, tools, schedule and realities of the job.
Run sterilizer spore-test records, set up operatories and review the day’s schedule with the dentist. From there, the day usually includes prepare treatment rooms and seat patients, review medical histories and take vital signs, and pass instruments and use suction during procedures. Mostly full-time weekday hours, sometimes with evenings or Saturdays to fit patient schedules.

Where dental assistants work
Nearly all dental assistants work in dentists’ offices; some work in specialty practices such as orthodontics or oral surgery, public health clinics or dental schools. Work is indoors, with frequent close patient contact. PPE such as gloves, masks and eyewear is worn throughout the day.
