Although they both sound alike, their roles are not interchangeable. As someone who will love to pursue a career in either of the fields, it is of the essence you understand the difference between Dental Hygienist and Dental Assistant.

Both dental assistants and dental hygienists work with dentists to help people care for their teeth.

However, the differences between dental assistant and dental hygienist positions center on their qualifications, the tasks I expect them to perform, and their level of interaction with patients.

Who is a Dental Hygienist?

Sometimes called an oral hygienist, a dental hygienist is a licensed dental professional registered with a dental association or regulatory body within their country of practice.

A dental hygienist is an oral health professional who teaches proper oral hygiene, conducts patient assessments, oral inspections, and teeth cleanings.

The primary concern of any dental hygienist is with the preventative oral healthcare of their patients.

Before taking the clinical and written examinations of the board, registered dental hygienists must hold an associate’s degree or a bachelor’s degree in dental hygiene from an accredited college or university.

Once registered, dental hygienists are primary health care professionals who work independently or with dentists and other dental professionals to provide comprehensive oral health care.

They have training and education that focus and specialize in preventing and treating many oral diseases.

Who is a Dental Assistant?

Unlike a dental hygienist, a dental assistant performs more administrative and dental office tasks. Also, referred to as a dental nurse, a dental assistant acts as an immediate aide to the dentist.

Dental assistants support other dental operators in providing efficient treatment to patients.

What Can You Do with a Dental Assisting Certificate?

Aside from working in a general dentistry office, dental assistants have several job options. Below are other jobs you can do with a dental assisting certificate:

  • Pediatrics: Good dental habits begin in childhood. If you love children, you will most likely enjoy a career in pediatric dentistry. Notwithstanding, you will need a solid understanding of the transition from baby teeth to adult teeth. Your job will also involve calming nervous children.
  • Dental schools: Dental schools often hire dental assistants to help students learn dental procedures. You can help in teaching others what you know here.
  • Oral Surgery:  Dental assistants are essential for the success of oral surgery. From the handling of the records to the preparation of the operating room and the patient, a dental assistant will remain busy working for an oral surgeon.

What are the Similarities Between a Dental Hygienist and a Dental Assistant?

Even with the differences, dental hygienists and dental assistants have a lot in common as they can be seen working hand in hand with each other.

One of the glaring similarities is that both work with the dentist and are part of the dental team. Other similarities include:

  • Assist the dentist
  • Patient care duties
  • Exam set-up duties
  • Technical and medical duties
  • Internships

Assist the Dentist

The dental hygienist and assistant are both employed to help the dentist. While the dental assistant helps in the administrative and office management, the dental hygienist majorly assists in medical procedures.

Patient Care Duties

The priority of both the dental hygienist and assistant is to care for the patients. Although the perform this function at different levels, the endpoint is to keep the patients at ease before, during, and after medical treatment.

For instance, the assistant is the patient’s first contact once he/she enters the clinic. He or she must welcome patients and get them ready for treatment.

The hygienist then takes over the cleaning and treatment independently or under the dentist’s watch while the assistant stays around to ensure that patients remain comfortable and relaxed through the procedure.

Exam Set-up Duties

Just like patient care, both ensure the exam room is set up for a patient’s visit. Although the dental assistant will usually take the lead, hygienists are also responsible for the exam preparation and set-up.

In addition, the two can often work together in preparing to receive patients.

Technical and Medical Duties

Dental assistants and hygienists carry out technical and medical tasks in different capacities. Dental assistants perform technical and medical tasks, such as taking patients’ blood pressure, making study cast of their teeth, and also taking x-rays.

On the other hand, dental hygienists will work much more medical duties with patients. Although they do not have the authority to make diagnoses, they often consult dentists and give advice.

In addition, hygienists also perform medical tasks such as charting, cleaning, and polishing of teeth, anesthetic application and assisting dentists in more advanced medical procedures.


Internships are very common and an important criterion for both the dental assistant and hygienist.

For dental assistants, they do much of their learning as interns. On the other hand, dental hygienes need to do their internship to practice. For instance, some states require 100+ hours of interning before a hygienist can earn his or her license.
