Nature of 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 different tools to complete their tasks. Hand and rotary instruments and ultrasonic devices are used to clean and polish teeth, including removing calculus, 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. 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 may 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.
Flexible scheduling is a distinctive feature of this job. Full-time, part-time, evening, and weekend schedules are 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. More than half of all dental hygienists worked part timeless than 35 hours a week.
Prospective dental hygienists must become licensed in the State in which they wish to practice. A degree from an accredited dental hygiene school is usually required along with licensure examinations.
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 a dental hygienist should take courses in biology, chemistry, and mathematics. Also, some dental hygiene programs require applicants to have completed at least 1 year of college. Specific entrance requirements vary from one school to another.
In 2006, there were 286 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 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 allows candidates to take its examinations if they have been trained through a State-regulated on-the-job program in a dentist’s office.
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 a patient’s mouth, with little room for error.
Dental hygienists held about 167,000 jobs in 2006. Because multiple job holding is common in this field, the number of jobs exceeds the number of hygienists. Almost all jobs for dental hygienists were in offices of dentists. A very small number worked for employment services, offices of physicians, or other industries.
Dental hygienists rank among the fastest growing occupations, and job prospects are expected to remain excellent.
Employment change. Employment of dental hygienists is expected to grow 30 percent through 2016, 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 the greater use of hygienists.
The demand for dental services will grow because of population growth, older people increasingly retaining more teeth, and a growing focus on preventative dental care. To meet this demand, facilities that provide dental care, particularly dentists’ offices, will increasingly employ dental hygienists, and more hygienists per office, to perform services that have been performed by dentists in the past.
Job prospects. Job prospects are expected to remain excellent. 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.
Projections data from the National Employment Matrix

Median hourly earnings of dental hygienists were $30.19 in May 2006. The middle 50 percent earned between $24.63 and $35.67 an hour. The lowest 10 percent earned less than $19.45, and the highest 10 percent earned more than $41.60 an hour.
Earnings vary by geographic location, employment setting, and years of experience. Dental hygienists may be paid on an hourly, daily, salary, or commission basis.
Benefits vary substantially by practice setting and may be contingent upon full-time employment. According to the American Dental Association, 86 percent of hygienists receive hospital and medical benefits.
Other workers supporting health practitioners in an office setting include dental assistants, medical assistants, occupational therapist assistants and aides, physical therapist assistants and aides, physician assistants, and registered nurses. Dental hygienists sometimes work with radiation technology, as do radiation therapists.
