Step 2. Pass the National Board Dental Hygiene Examination (NBDHE)

You can sign up online to take the NBDHE, a test that is administered by the Joint Commission on National Dental Examinations (JCNDE). You will be eligible to take this exam once you graduate from an ADA-approved dental hygienist program, and may also take it as a student if your instructor certifies that you are ready.

The NBDHE is made up of 350 multiple-choice questions in total and divided into two parts. The first portion involves 200 discipline-centric questions that can be divided into three main subjects:

  • Community health and research principles
  • Clinical dental hygienist services
  • Scientific principles behind the practice of dental hygiene

The second portion is comprised of 150 scenario-based questions involving between 12 and 15 hypothetical patients. These questions are drawn from seven main subject areas:

  • Professional responsibility
  • Patient characteristics assessment
  • Supportive treatment and service
  • Interpreting and obtaining x-rays
  • Use of preventative agents
  • Performance of periodontal procedures

You can take the NBDHE at Pearson VUE testing centers across America, four of which are located in Tennessee in the cities of:

  • Brentwood
  • Nashville
  • Chattanooga
  • Knoxville

 


 

Step 3. Pass a Board-Approved Clinical Dental Examination

You will also need to pass a clinical dental exam that is approved by the Tennessee Board of Dentistry, such as those offered by one the following agencies:

The typical content of a clinical exam will involve a demonstration of the following skills:

  • Teeth cleaning
  • X-rays of the oral cavity
  • Detection and proper removal of calculus
  • Measuring the depth of periodontal pockets

Your resulting exam score will be automatically sent to the Tennessee Board of Dentistry.

If you are already a licensed dental hygienist in a different state who has been actively practicing for at least three of the past five years, you may be exempt from taking a regional clinical examination provided you have not previously failed another state’s required regional exam.

 


 

Step 4. Consider Additional Optional Dental Hygienist Qualifications

In addition to the duties associated with the basic dental hygienist job description, the Tennessee Board of Dentistry also permits the following four expanded duties for qualifying dental hygienists:

Administration of Local Anesthesia

To be certified by the Tennessee Board of Dentistry to administer local anesthesia you will need to qualify via one of three recognized routes:

  • Complete an ADA-approved course covering the administration of local anesthesia
  • Complete a state Board of Dentistry-approved course that focuses on the administration of local anesthesia
  • Complete an out-of-state course that covers the administration of local anesthesia that the Board deems to be valid

Once you have completed one of these requirements you will need to fill out an application for certification that must be submitted to the Board. The Board will then consider your eligibility for certification in this area.

Monitoring and Administering Nitrous Oxide

If you are in good standing with the state’s Board of Dentistry you can apply for certification to monitor and administer nitrous oxide. To be eligible for this duty you must either complete a Board-approved course dealing with the monitoring and administration of nitrous oxide, or have completed such a course as part of your ADA-approved dental hygienist education.

This certification is valid as long as you maintain your dental hygienist license with the Tennessee Board of Dentistry.

Restorative and Prosthetic Function

Experienced dental assistants in Tennessee also have the option of becoming certified to perform restorative and/or prosthetic functions. To be eligible for these Board-issued certifications you will need to meet two requirements:

  • Have at least two full-time years of experience as a dental hygienist
  • Complete a Board-approved course in restorative and/or prosthetic functions

Certification in these areas are valid as long as you maintain your dental hygienist license.

 


 

Step 5. Apply for Licensure with the Tennessee Board of Dentistry

You will need to complete two final steps before you will be ready to apply for a dental hygienist license. The first of these is to obtain an approved CPR certification, such as:

  • Basic Life Support for the Healthcare Provider
  • CPR/AED for the Professional Rescuer

Next you will also need to complete a criminal background check. Once you have accomplished these two tasks you will be ready to submit an application for licensure.

Along with a completed application packet, the following will need to be submitted to the Tennessee Board of Dentistry:

  • Official transcripts from your dental hygiene school in Tennessee or another state, submitted by the institution directly to the Board
  • Official NBDHE scores sent directly to the Board by the JCNDE
  • Two letters of recommendation from dental professionals
  • Application fee
  • Proof of approved CPR certification
  • Copy of any dental hygiene licenses from different states, if applicable

It can take up to 14 business days for materials submitted to the Board’s office to be accumulated in your application file. Once you receive your license you will be able to apply to dental hygienist jobs in Tennessee.

 


 

Step 6. Maintain Your Tennessee Dental Hygienist License

Your license will expire on the last day of your birth month. To maintain a dental hygienist license you must keep your CPR certification up-to-date. You also need to complete at least 30 hours of continuing education every two years. Two of these hours must be in the area of chemical dependency, and up to half of your continuing education may be web-based.

You can find additional information about continuing education opportunities, job vacancies, and the latest updates on legislation in the dental hygienist field through professional organizations such as the Tennessee Dental Hygienist Association (TDHA).

  • 1,030 in the greater Nashville-Murfreesboro area
  • 570 in the greater Memphis area
  • 540 in Knoxville
  • 270 in the greater Chattanooga area
  • 160 in the greater Kingsport area
