When looking at a career as a dental hygienist or a dental assistant, these two job titles may seem interchangeable. As you begin to look into the roles and responsibilities of each one, you soon realize that these are separate professions. While some of their job duties overlap, the daily work of each dental professional is different. In this article, we look at the differences and similarities between dental hygiene vs. dental assisting.

  • Use handheld tools to remove tartar and plaque from patients' teeth.
  • Examine patients' mouths for signs of tooth decay, gum issues and other oral diseases.
  • Take X-rays of patients' teeth for the dentist to review.
  • Communicate any questions or concerns for the dentist to address when examining a patient.
  • Document treatment plans and examination findings on a patient's file.
  • Review patients' dental history to learn more about their oral hygiene habits and previous issues.
  • Meet with the dentist to come up with a treatment plan for a patient.
  • Teach patients the best practices for effective oral hygiene.

The differences between dental hygiene vs. dental assisting

Here are the main differences between a dental hygienist vs. a dental assistant:

Administrative duties

While both a dental hygienist and a dental assistant may do administrative duties, a dental assistant tends to be more involved in these kinds of responsibilities. Dental assistants tend to be in charge of processing patient paperwork, getting them checked in and out of their appointment and scheduling follow-up care.

Patient care

A dental assistant tends to be responsible for everything leading up to when a dental hygienist works with a patient. The dental assistant prepares the examination room, greets patients, leads them to the examination room and learns about any dental concerns a patient might have. Depending on your location, a dental assistant may be able to do some basic cleaning procedures, such as polishing teeth and administering fluoride, topical anesthetic and sealants.

When comparing these two careers, a dental hygienist's role heavily focuses on cleaning and examining a patient's teeth and gums. While they perform routine cleanings, they may also perform more extensive care for patients who have a wide variety of oral diseases and issues. A dental hygienist collaborates with the dentist to look for signs of tooth decay and other issues in the mouth. They are responsible for educating patients about proper oral care.


While each state has its own educational and training requirements, dental hygienists are typically in school longer than dental assistants. A dental hygienist typically needs to earn an associate's degree in dental hygiene, with many programs taking you three years to complete. After completing their program, dental hygienists often have to pass an accredited training program and multiple exams to earn their license to practice.

The most education dental assistants usually have to complete is a one-year diploma or certificate program. They may also have to earn a license to work as a dental assistant. Keep in mind, these factors vary by state.
