About Dental Hygenists

Significant Points

  • A degree from an accredited dental hygiene school and a State license are required for this job.
  • Dental hygienists rank among the fastest growing occupations.
  • Job prospects are expected to be favorable in most areas, but strong competition for jobs is likely in some areas.
  • About half of all dental hygienists work part time, and flexible scheduling is a distinctive feature of this job.

Nature of the Work

Dental hygienists remove soft and hard deposits from teeth, teach patients how to practice good oral hygiene, and provide other preventive dental care. They examine patients’ teeth and gums, recording the presence of diseases or abnormalities.

Dental hygienists use an assortment of tools to complete their tasks. Hand and rotary instruments and ultrasonic devices are used to clean and polish teeth, which includes removing tartar, stains, and plaque. Hygienists use x-ray machines to take dental pictures, and sometimes develop the film. They may use models of teeth to explain oral hygiene, perform root planning as a periodontal therapy, or apply cavity-preventative agents such as fluorides and pit and fissure sealants.

Other tasks hygienists may perform vary by State. In some States, hygienists are allowed to administer anesthetics, while in others they administer local anesthetics using syringes. Some States also allow hygienists to place and carve filling materials, temporary fillings, and periodontal dressings; remove sutures; and smooth and polish metal restorations.

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

Hygienists sometimes make a diagnosis and other times prepare clinical and laboratory diagnostic tests for the dentist to interpret. Hygienists sometimes work chair-side with the dentist during treatment.

Work environment. Dental hygienists work in clean, well-lighted offices. Important health safeguards include strict adherence to proper radiological procedures and the use of appropriate protective devices when administering anesthetic gas. Dental hygienists also wear safety glasses, surgical masks, and gloves to protect themselves and patients from infectious diseases. Dental hygienists also should be careful to avoid possible shoulder and neck injury from sitting for long periods of time while working with patients.

Flexible scheduling is a distinctive feature of this job. Full-time, part-time, evening, and weekend schedules are common. Dentists frequently hire hygienists to work only 2 or 3 days a week, so hygienists may hold jobs in more than one dental office. In 2008, about half of all dental hygienists worked part time—less than 35 hours a week.

Training, Other Qualifications, and Advancement

A degree from an accredited dental hygiene school and a State license are required for this job.

Education and training. A high school diploma and college entrance test scores are usually required for admission to a dental hygiene program. High school students interested in becoming dental hygienists should take courses in biology, chemistry, and mathematics. Some dental hygiene programs also require applicants to have completed at least one year of college. Specific entrance requirements typically vary from one school to another.

In 2008, there were 301 dental hygiene programs accredited by the Commission on Dental Accreditation. Most dental hygiene programs grant an associate degree, although some also offer a certificate, a bachelor’s degree, or a master’s degree. A minimum of an associate degree or certificate in dental hygiene is generally required for practice in a private dental office. A bachelor’s or master’s degree usually is required for research, teaching, or clinical practice in public or school health programs.

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.

Licensure. Dental hygienists must be licensed by the State in which they practice. Nearly all States require candidates to graduate from an accredited dental hygiene school and pass both a written and clinical examination. The American Dental Association’s (ADA) Joint Commission on National Dental Examinations administers the written examination, which is accepted by all States and the District of Columbia. State or regional testing agencies administer the clinical examination. In addition, most States require an examination on the legal aspects of dental hygiene practice. Alabama is the only State that does not require candidates to take the ADA written exam. Instead, they require that candidates meet the requirements of the Alabama Dental Hygiene Program, which mandates taking courses, completing on-the-job training at a dentist’s office, and passing a separate State administered licensing examination.

Other qualifications. Dental hygienists should work well with others because they work closely with dentists and dental assistants, as well as dealing directly with patients. Hygienists also need good manual dexterity, because they use dental instruments within patients’ mouths, with little room for error.

Advancement. Advancement opportunities usually come from working outside a typical dentist’s office, and usually require a bachelor’s or master’s degree in dental hygiene. Some dental hygienists may choose to pursue a career teaching at a dental hygiene program, working in public health, or working in a corporate setting.

Employment

Dental hygienists held about 174,100 jobs in 2008. Because multiple job holding is common in this field, the number of jobs exceeds the number of hygienists. About 51 percent of dental hygienists worked part time. Almost all jobs for dental hygienists—about 96 percent—were in offices of dentists. A very small number worked for employment services, in physicians’ offices, or in other industries.

Job Outlook

Dental hygienists rank among the fastest growing occupations. Job prospects are expected to be favorable in most areas, but competition for jobs is likely in some areas.

Employment change. Employment of dental hygienists is expected to grow 36 percent through 2018, which is much faster than the average for all occupations. This projected growth ranks dental hygienists among the fastest growing occupations, in response to increasing demand for dental care and more use of hygienists.

The demand for dental services will grow because of population growth, older people increasingly retaining more teeth, and a growing emphasis on preventative dental care. To help meet this demand, facilities that provide dental care, particularly dentists’ offices, will increasingly employ dental hygienists, often to perform services that have been performed by dentists in the past. Ongoing research indicating a link between oral health and general health also will spur the demand for preventative dental services, which are typically provided by dental hygienists.

Job prospects. Job prospects are expected to be favorable in most areas, but will vary by geographical location. Because graduates are permitted to practice only in the State in which they are licensed, hygienists wishing to practice in areas that have an abundance of dental hygiene programs may experience strong competition for jobs.

Older dentists, who have been less likely to employ dental hygienists, are leaving the occupation and will be replaced by recent graduates, who are more likely to employ one or more hygienists. In addition, as dentists’ workloads increase, they are expected to hire more hygienists to perform preventive dental care, such as cleaning, so that they may devote their own time to more complex procedures.
