Dental Hygienists

• Nature of the Work

  Dental hygienists clean teeth and provide other preventive dental care as well as teach patients how to practice good oral hygiene. Hygienists examine patients' teeth and gums, recording the presence of diseases or abnormalities. They remove calculus, stains, and plaque from teeth; apply cavity preventive agents such as fluorides and pit and fissure sealants; take and develop dental x rays; place temporary fillings and periodontal dressings; remove sutures; and smooth and polish metal restorations. In some States, hygienists administer local anesthetics and anesthetic gas, and place and carve filling materials.

  Dental hygienists also help patients develop and maintain good oral health. For example, they may explain the relationship between diet and oral health, inform patients how to select toothbrushes, and show patients how to brush and floss their teeth.

  Dental hygienists use hand and rotary instruments to clean teeth, x-ray machines to take dental pictures, syringes with needles to administer local anesthetics, and models of teeth to explain oral hygiene.

• Working Conditions

  Flexible scheduling is a distinctive feature of this job. Full-time, part-time, evening, and weekend work is 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.

  Dental hygienists work in clean, well-lighted offices. Important health safeguards include strict adherence to proper radiological procedures and use of appropriate protective devices when administering anesthetic gas. Dental hygienists also wear safety glasses, surgical masks and gloves to protect themselves from infectious diseases such as hepatitis. The occupation is one of several covered by the Consumer-Patient Radiation Health and Safety Act of 1981, which encourages the States to adopt uniform standards for the training and certification of individuals who perform medical and dental radiological procedures.

• Employment

  Dental hygienists held about 127,000 jobs in 1994. Because multiple jobholding is common in this field, the number of jobs greatly exceeds the number of hygienists. About half of all dental hygienists usually worked part time-less than 35 hours a week.

  Almost all dental hygienists work in private dental offices. Some work in public health agencies, school systems, hospitals, and clinics.

• Training, Other Qualifications, and Advancement

  Dental hygienists must be licensed by the State in which they practice. To qualify for licensure, a candidate must graduate from an accredited dental hygiene school and pass both a written and a clinical examination. The American Dental Association Joint Commission on National Dental Examinations administers the written examination that is accepted by all States and the District of Columbia. State or regional testing agencies administer the clinical examination. In addition, examinations on legal aspects of dental hygiene practice are required by most States. Alabama also allows candidates to take its examination if they have been trained through a State-regulated on-the-job program in a dentist's office.

  In 1995, 212 programs in dental hygiene were accredited by the Commission on Dental Accreditation. Although some programs lead to a bachelor's degree, most grant an associate degree. Ten universities offer master's degree programs in dental hygiene.

  An associate degree is sufficient for practice in a private dental office. A bachelor's or master's degree is usually required for research, teaching, or clinical practice in public or school health programs.

  About half of the dental hygiene programs prefer applicants who have completed at least 1 year of college. Some of the bachelor's degree programs require applicants to have completed 2 years. However, requirements vary from school to school. These schools offer laboratory, clinical, and classroom instruction in subjects such as anatomy, physiology, chemistry, microbiology, pharmacology, nutrition, radiography, histology (the study of tissue structure), periodontology (the study of gum diseases), pathology, dental materials, clinical dental hygiene, and social and behavioral sciences.

  Dental hygienists should work well with others and must have manual dexterity because they use dental instruments with little room for error within a patient's mouth. Recommended high school courses for aspiring dental hygienists include biology, chemistry, and mathematics.

• Job Outlook

  Employment of dental hygienists is expected to grow much faster than the average for all occupations through the year 2005 in response to increasing demand for dental care and the greater substitution of hygienists for services previously performed by dentists. Job prospects are expected to remain very good unless the number of dental hygienist program graduates grows much faster than during the last decade and results in a much larger pool of qualified applicants.

  Demand will be stimulated by population growth, and greater retention of natural teeth by the larger number of middle-aged and elderly people. Also, dentists are likely to employ more hygienists, for several reasons. Older dentists, who are less likely to employ dental hygienists, will leave and be replaced by recent graduates, who are more likely to do so. In addition, as dentists' workloads increase, they are expected to hire more hygienists to perform preventive dental care such as cleaning, so they may use their own time more profitably.

• Earnings

  Earnings of dental hygienists are affected by geographic location, employment setting, and education and experience. Dental hygienists who work in private dental offices may be paid on an hourly, daily, salary, or commission basis.

  According to the American Dental Association, dental hygienists who worked 32 hours a week or more averaged $675.50 a week in 1993; the average hourly earnings for all dental hygienists was $21.10.

  Benefits vary substantially by practice setting, and may be contingent upon full-time employment. Dental hygienists who work for school systems, public health agencies, the Federal Government, or State agencies usually have substantial benefits.

• Related Occupations

  Workers in other occupations supporting health practitioners in an office setting include dental assistants, ophthalmic medical assistants, podiatric assistants, office nurses, medical assistants, physician assistants, physical therapy assistants, and occupational therapy assistants.
