Dental Assistant


Dental assistants perform a variety of patient care, office and laboratory duties. They sterilize and disinfect instruments and equipment, lay out instruments and prepare materials required to treat each patient, and obtain and update patients’ dental records. Dental assistants make patients comfortable in the dental chair and prepare them for treatment. During dental procedures, assistants work at chair-side as dentists examine and treat patients. They hand instruments and materials to dentists and keep patients’ mouths dry and clear by using suction hoses or other devices. They also instruct patients on postoperative and general oral healthcare.

Work Environment

Dental assistants must work closely with, and under the supervision of dentists; therefore, they work almost exclusively in the offices of dental practices.  Assistants must wear gloves, and protective eyewear, masks, and clothing to protect themselves and their patients from infectious diseases.  They must also follow safety procedures to minimize the risks associated with the use of x-ray machines.

According to the Bureau of Labor Statistics, almost half of all dental assistants work a 40-hour week.  More than one-third of dental assistants work part-time.

Job Outlook

Employment of dental assistants is expected to increase 36 percent from 2008 to 2018, much faster than the average for all occupations.  In fact, dental assistants are expected to be among the fastest growing occupations over the 2008 to 2018 projection period.  Population growth, greater retention of natural teeth my middle-aged and older people, and an increased focus on preventative dental care for younger generations will fuel demand for dental services.  Also, as dentists’ workloads increase, they are expected to hire more assistants to perform routine tasks, so that they may devote their own time to more complex procedures.
