4 Steps to Becoming a Dental Hygienist

The specific requirements to become a dental hygienist may vary slightly depending on your state, but the basic requirements for these professionals are the same. If you want to become a dental hygienist, you need to complete four steps:

  1. 1
  2. 2
    Pass the National Board Dental Hygiene Examination (NBDHE) from the Joint Commission on National Dental Examinations (JCNDE).
  3. 3
    Pass an approved clinical board examination for your region or state.
  4. 4
    Obtain licensure from the appropriate state dental board.

Keep reading for a deeper dive into the steps required to become a dental hygienist.

Step 1: Graduate From an Accredited Dental Hygiene Program

Your first step is to graduate from an associate degree program in dental hygiene accredited by the Commission on Dental Accreditation (CODA). In this program, you will explore a variety of subjects, including biomedical sciences, dental hygiene sciences, and dental sciences.

Many dental hygiene programs incorporate practical training into the curriculum to help you gain supervised clinical experience. This usually entails 8-12 hours of hands-on training per week.

Step 2: Pass the National Board Dental Hygiene Examination

After you've completed your associate program, you can now take the NBDHE. This exam assesses your knowledge of dental hygiene information and your ability to apply your clinical skills in a real-world context.

To pass this exam, you'll need to score a minimum of 75. It's crucial to prepare for this exam, as it's a major step in your journey to become a dental hygienist. Make the most of your textbooks, lecture notes, and study materials, and be sure to take practice exams to familiarize yourself with the test's format.

Step 3: Pass an Approved State Clinical Board Examination

After the NBDHE, you'll need to pass an approved state or regional clinical board examination. The specifics of this exam will vary depending on your state, so be sure to check with your state's dental board for details.

For example, in Virginia, the board only accepts the American Dental Examination (ADEX) for the clinical component. However, in California, the board requires the Central Regional Dental Testing Service (CRDTS) exam. This is why it's crucial to check your state's specific licensure requirements.

Step 4: Obtain State Licensure

The final step to becoming a dental hygienist is to obtain licensure from your state's dental board. This involves submitting an application, along with proof of your education, your NBDHE score, and proof that you've passed your state or regional clinical board examination.

You'll also need to meet any additional requirements outlined by your state's dental board, which may include additional exams or credentials. Once you've obtained your license, you're ready to start working as a dental hygienist.
