Dental hygienists held about 192,800 jobs in 2012. Almost all dental hygienists work in dentists’ offices. They work closely with dentists and dental assistants.
Dental hygienists wear safety glasses, surgical masks, and gloves to protect themselves and patients from infectious diseases. When taking x rays, they follow strict procedures to protect themselves and patients. They may spend long periods bending over to work on patients.
More than half of dental hygienists worked part time in 2012. Dentists often hire hygienists to work only a few days a week, so some hygienists work for more than one dentist.

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 1 year of college. Specific entrance requirements vary by school.
Most schools offer laboratory, clinical, and classroom instruction. Hygienists study anatomy, physiology, nutrition, radiography, and periodontology, which is the study of gum disease.
Licenses, Certifications, and Registrations
Every state requires dental hygienists to be licensed; requirements vary by state. In most states, a degree from an accredited dental hygiene program and passing grades on written and practical examinations are required for licensure. For specific application requirements, contact your state’s medical or health board.
Dental hygienists typically have an interest in the Building, Helping and Organizing interest areas, according to the Holland Code framework. The Building interest area indicates a focus on working with tools and machines, and making or fixing practical things. The Helping interest area indicates a focus on assisting, serving, counseling, or teaching other people. The Organizing interest area indicates a focus on working with information and processes to keep things arranged in orderly systems.
If you are not sure whether you have a Building or Helping or Organizing interest which might fit with a career as a dental hygienist, you can take a career test to measure your interests.
Dental hygienists should also possess the following specific qualities:
Detail oriented. Dental hygienists must follow specific rules and protocols to help dentists diagnose and treat a patient. In rare cases, dental hygienists work without the direct supervision of a dentist.
Dexterity. Dental hygienists must be good at working with their hands. They generally work in tight quarters on a small part of the body, using very precise tools and instruments.
Interpersonal skills. Dental hygienists must work closely with dentists and patients.
Physical stamina. Dental hygienists should be comfortable performing physical tasks, such as bending over patients for a long time.
The median annual wage for dental hygienists was $70,210 in May 2012. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $46,540, and the top 10 percent earned more than $96,280.
Some dental hygienists receive benefits, such as vacation, sick leave, and contributions to their retirement fund. However, benefits vary by employer and may be available only to full-time workers.

Employment of dental hygienists is projected to grow 33 percent from 2012 to 2022, much faster than the average for all occupations. Ongoing research linking oral health and general health will continue to spur the demand for preventative dental services, which are often provided by dental hygienists.
As their practices expand, dentists will hire more hygienists to perform routine dental care, allowing the dentist to see more patients. In addition, as the large baby-boom population ages and people keep more of their original teeth than previous generations did, the need to maintain and treat these teeth will continue to drive demand for dental care.
Federal health legislation is expected to expand the number of patients who have access to health insurance. People with new or expanded dental insurance coverage will be more likely to visit a dentist than in the past. As a result, the demand for all dental services, including those performed by hygienists, will increase.
