Dental Hygienist – Who are they & What they do?

A dental hygienist may be the first person that you meet when you visit a dentist. A dental hygienist is responsible for cleaning your teeth, examining them for signs of disease and educating you on the best ways to keep your mouth and teeth healthy. In the dental office, the dentist and the hygienist work together to meet the oral health needs of patients.

Every state requires hygienists to be licensed. However, the requirement varies with the state. In most states, a degree from an accredited dental hygiene program and passing grades on written and clinical examination are required for the license. This article will explain what a dental hygienist is and the role they play in a dental practice.


What is a dental hygienist?

A dental hygienist is a licensed dental professional who is registered with a dental association or regulatory body within their country of practice. They work in a range of dental settings, from independent, private, or specialist practices to the public sector.

They work together with dentists, dental therapists, oral health therapists as well as other dental professionals.


In the dental office, the dentist and the hygienist work together to meet the oral health needs of the patients. Some of the services provided by a hygienist may include –

  • Patient screening procedures, such as assessment of oral health conditions, review of the health history, oral cancer screening, head and neck inspection, dental charting, and taking blood pressure and pulse.
  • Taking and developing dental radiographs (x-rays).
  • Removing calculus and plaque (hard and soft deposits) from all surfaces of the teeth.
  • Applying preventive materials to the teeth.
  • Teaching patients appropriate oral hygiene strategies to maintain oral health.
  • Counseling patients about proper nutrition and its impact on oral health.
  • Making impressions of patient’s teeth for study casts.
  • Performing documentation and office management activities.

Education requirements for a dental hygienist

A dental hygienist typically needs an associate degree in dental hygiene. Dental hygiene programs are commonly found in community colleges, technical schools, and universities. Programs usually take three years to complete and offer laboratory, clinical, and classroom instruction.

Areas of study include physiology, nutrition, radiography, pathology, medical ethics, anatomy, patient management, and periodontics, which is the study of gum disease. High school students interested in becoming hygienist should take courses in biology, chemistry, and math.

Most dental hygiene programs also require applicants to complete prerequisites, which often include college-level courses.


The median annual wage for a dental hygienist is $70,000. Benefits such as vacation, sick leave, and retirement contributions vary by the employer and may be available to full-time workers only. About half of dental hygienists work part-time. Dentists often hire hygienists to work only a few days a week, so some hygienists work for more than one dentist.
