Detailed Guide for

Dental Hygienists in Los Angeles County

May also be called: Registered Dental Hygienists (RDH) and Hygienists

What Would I Do?

Dental Hygienists are part of the dental care team that includes dentists, dental assistants, and dental technicians working together to prevent and control gum disease and the development of tooth decay.

Dental Hygienists remove plaque and clean and polish teeth using scaling instruments and a rotating polisher. They apply decay preventive agents such as fluorides and sealants, chart medical and dental histories, and take and develop dental x-ray films. They also screen patients, take a medical history, and add information to the patient’s chart.

Hygienists teach patients good oral hygiene practices and examine the mouth for disease. They may also provide nutritional counseling and instruct patients on how to take care of their teeth so they can last a lifetime.

Hygienists do not diagnose dental problems, but over time they have acquired more responsibility. They can administer anesthesia for pain control and prepare clinical and laboratory diagnostic tests for interpretation by dentists. They are increasingly involved in periodontal therapies including root planing, micro-ultrasonics, and soft tissue curettage.

Dental Hygienists who are employed in public health agencies such as Indian Health Services or in community health programs help dentists assess dental care needs and plan appropriate dental health programs. This includes supervising field training for dental hygiene students. They also provide clinical services, especially for children.

Dental Hygienists who work in hospitals, clinics, and nursing and convalescent homes assist dentists with oral health problems of the patients. At colleges and universities, they engage in research in the field, teach dental hygiene programs, and may be employed as faculty members in dental schools.

Working Conditions

Dental Hygienists work in pleasant, modern, well-lit, heated, and ventilated surroundings that usually have the latest dental equipment. Some of the locations in which they work include dentists’ offices, armed forces bases, nursing homes, and public health clinics.

While most of the time Dental Hygienists work sitting down, they can still develop back and neck pain. Repetitive hand and wrist movements used in their work may cause Carpal Tunnel Syndrome.

Other hazards include exposure to infectious diseases and possible overexposure to radiation from x-rays. Risks are minimized by using the appropriate safety gear such as masks, safety glasses, and special aprons. Important health protection in this occupation includes regular checkups and strict adherence to safety procedures for the use of x-ray equipment.

The work requires good vision (may be corrected) and finger dexterity for close attention to detail and handling of sharp instruments. Constant work with other dental team members in a confined space is common.

It is common for Hygienists to work part-time in one dental office, and combine that with another part-time schedule in another office. A variety of schedules may be available, including full-time, part-time, evening, and weekend work.

Licensed Dental Hygienists are eligible to join the American Dental Hygienists Association and the California Dental Hygienists Association.

How Do I Qualify?

Education, Training, and Other Requirements

Dental Hygienists receive their education through academic programs at community colleges, technical colleges, dental schools, or universities. The majority of community college programs take at least two years to complete, with graduates receiving associate degrees. This degree allows a Hygienist to take licensure examinations (this includes both a national written examination and a State clinical examination) and to work in a dental office. University-based dental hygiene programs may offer baccalaureate and master's degrees, which generally require at least two years of further schooling. These additional degrees may be required to embark on a career in teaching or research, as well as for clinical practice in school or public health programs.

Dental hygiene program admission requirements vary depending upon the specific school. Most programs show a preference for individuals who have completed at least one year of college. Some baccalaureate degree programs require that applicants complete two years of college prior to enrollment in the dental hygiene program. Counselors, advisors, and prospective students should contact the particular dental hygiene program of interest for specific program requirements.

Dental hygiene education programs provide students with clinical education in the form of supervised patient care experiences. Additionally, these programs include courses in liberal arts (e.g., English, speech, sociology, and psychology); basic sciences (e.g., anatomy, physiology, pharmacology, immunology, chemistry, microbiology, and pathology); and clinical sciences (e.g., dental hygiene, radiology, and dental materials).


Experience is preferred, but not required, by employers. Extensive experience is often rewarded with better pay.

Early Career Planning

High school courses such as health, biology, English, psychology, chemistry, mathematics, and speech will be beneficial in a dental hygiene career.

Continuing Education

Hygienists must complete 25 continuing education units every two years to meet state requirements.

Licensing and Certification

To be licensed by the California Department of Consumer Affairs Committee on Dental Auxiliaries, the educational program must be approved by the American Dental Association (ADA). Contact the agency that issues the license for additional information. Click on the license title below for details.

Prospective Registered Dental Hygienists must satisfy four requirements to be licensed in California:

  • Graduate from an ADA-accredited hygiene program;
  • Complete approved courses in the use of instruments to clean soft tissue (such as gums), administration of nitrous oxide, and administration of local anesthesia;
  • Pass the national written examination; and
  • Pass a clinical examination and examinations in Ethics and California Law administered by the Committee on Dental Auxiliaries (COMDA).
In addition, applicants must be fingerprinted. If a check reveals a criminal history, arrest and court records must be investigated, and a license may be denied on this basis.
