How to Become a Dental Hygienist

Dental hygienists clean teeth, examine patients for signs of oral diseases, and provide preventive care and education on good oral hygiene practices. It's a steady, well-paid career that offers excellent work-life balance — most dental hygienists work 3–4 days per week and rarely take their work home with them.

According to the BLS, dental hygienists earn a median annual wage of $87,530 — making it one of the highest-paid two-year degree careers in healthcare. Job growth is projected at 9% through 2033.

What Does a Dental Hygienist Do?

In a typical patient appointment, a dental hygienist will:

Most hygienists work in private dental offices, though opportunities also exist in schools, public health clinics, and research settings.

Step 1 — Complete an Accredited Dental Hygiene Program

To become a dental hygienist, you must graduate from a dental hygiene program accredited by the Commission on Dental Accreditation (CODA). Most programs award an Associate Degree in Dental Hygiene (ASDH) and take 2–3 years to complete, including prerequisite courses.

Common prerequisites include:

The dental hygiene program itself covers dental anatomy, radiology, periodontology, pharmacology, clinical techniques, and patient management.

Pro Tip: Dental hygiene programs are competitive — many have waitlists. Strengthen your application by volunteering or working as a dental assistant first. This demonstrates commitment and gives you hands-on experience in a dental setting.

Step 2 — Pass the NBDHE and Clinical Boards

After graduating, you must pass two licensing exams:

  1. National Board Dental Hygiene Examination (NBDHE): A 350-question computer-based exam covering dental hygiene science and clinical dental hygiene
  2. Clinical/Regional Board: A hands-on patient examination administered by regional boards such as WREB, CRDTS, or CSCE — requirements vary by state

As of 2023, many states accept the Objective Structured Clinical Examination (OSCE) in place of traditional live-patient board exams.

Step 3 — Apply for State Licensure

Each state issues its own dental hygiene license through the State Board of Dentistry. You'll submit your board exam scores, transcripts, and licensing fee. Some states also require a background check and CPR certification.

Most states require 12–30 continuing education (CE) hours every renewal period (usually 2 years) to maintain licensure.

Dental Hygienist Salary and Work-Life Balance

Dental hygiene stands out not just for its pay but for its quality of life:

Top-paying states include California ($119,150 median), Alaska, and Washington state.
