How to Become a DANB-Certified Dental Assistant

Certified dental assistants are a critical component of an efficient dentist’s office. Without these knowledgeable professionals, dentists could not do their essential work. Certified dental assistants (CDAs) offer chairside support on industry equipment and surgical and procedural assistance with fillings, extractions, and crowns. Responsibilities include patient care, laboratory testing, and administrative duties such as scheduling and bill processing. One way to earn a dental assisting certification in the United States is through the Dental Assisting National Board (DANB).

Thirty-nine require DANB certifications and exams by law, including the District of Columbia and federal government organizations such as the Department of Veterans Affairs and the U.S. Air Force.

The most commonly obtained certification through the DANB is that of the Certified Dental Assistant (CDA). Applicants must pass three individual exams to receive a CDA certification through the DANB, which includes the General Chairside Assisting (GC) exam, the Radiation Health and Safety (RHS) exam, and the Infection Control (ICE) exam. The DANB offers three dental assistant certifications:

  • National Entry Level Dental Assistant (NELDA)
  • Certified Preventive Functions Dental Assistant (CPFDA)
  • Certified Restorative Functions Dental Assistant (CRFDA) certification

The Bureau of Labor Statistics (BLS) predicts the field will add 30,100 jobs between 2021 and 2031. The most common level of education for CDAs is postsecondary nondegree, typically an associate’s degree. It should be noted that those who go on to become CDAs are professionals who often hold a two-year dental hygienist degree at a minimum.

Keep reading to learn more about how you can become a certified dental assistant, including information about education, career pathways, industry certifications, and specialization. Please note that no two states have precisely the same requirements for licensure or certification, and only 39 require certification through the DANB. This piece covers the three eligibility pathways for dental assistant certification outlined by DANB, going into detail about further requirements below. CODA, the Commission on Dental Accreditation, oversees accreditation, curriculum, and compliance for educational programs in the United States.

Step-by-Step Guide to Becoming a DANB-Certified Dental Assistant (CDA)

Step 1: Graduate from high school (four years)

Before graduating from high school, there are many ways that students can prepare for a career as a DANB-certified dental assistant. Coursework should focus on biology, anatomy, and biology, which will help prepare for specialized medical work. The DANB accepts high school dental assisting programs for its National Entry Level Dental Assistant certification, or NELDA, so long as it includes at least a semester of dental assisting coursework or curriculum.

Step 2a: Graduate from a dental assisting program (nine months to two years)

Community colleges and training or vocational schools are the most common places to obtain dental assisting credentials. Depending on whether a student is pursuing a certificate, diploma, or associate degree program, it can take one to two years. A vital element of a cutting-edge CDA program is a hands-on component that provides ample opportunities to test skills.

Students interested in pursuing these sorts of careers might be overwhelmed by the various paths available to them. The standard diploma and certificate programs offer practical educational options for people not interested in earning a more advanced degree. Another benefit of this is that CDAs can enter the workforce more quickly because the educational period is shorter. Some of the most common courses include office administration, dental materials, communications, radiography, anatomy, biology, physiology, inorganic chemistry, organic chemistry, and virology.

For certificate programs, coursework is usually completed within 12 months, while an associate’s degree in dental assisting takes two years. Schools like the Indiana University – Purdue University Indianapolis School of Dentistry and the University of Alabama at Birmingham’s School of Dentistry maintain top-rated dental assistants and hygienist programs.

Indiana University–Purdue University Indianapolis (IUPUI)

The Indiana University’s School of Dentistry offers a CODA-accredited on-campus certificate in dental assisting that requires the successful completion of 30 credits. Students in this program must complete at least 300 clinical hours to earn the certificate.

Step 2b: Complete at least 3,500 hours of DANB-approved work experience (two to four years)

This pathway is for those individuals who have experience in the field but lack the traditional diploma, degree, or certificate of a formal dental assistant education. A registered, licensed dentist must confirm that you have accrued 3,500 hours of dental assistant work in a facility or state that might not expressly require CDAs to be officially licensed. If accepted, the 3,500 hours count as an entire course of study in hands-on CDA training.

Step 2c: Complete an externship (timeline varies, optional)

Signing up for an externship is an excellent means of gaining further dental training. These positions often run concurrently with education or post-certification training and reskilling programs and give dental assistants a way to gain experience and make their job applications stand out.

Many academic programs host externships as an ancillary component of a CDA curriculum. This helps students sharpen their CDA skills and gain valuable chairside experience in oral anatomy, dental pathology, oral hygiene, radiology, dental pharmacology, and oral hygiene.

Step 3: Earn certification in CPR from a DANB-certified provider (one to three months)

While this certification might seem obvious, all dental professionals must be trained in CPR, basic first aid, services, or advanced cardiac life support. The DANB accepts CPR, BLS, and ACLS credentials from any entities below provided that the course is partially based on CPR and a hands-on exam.

These include the American Environmental Health and Safety, American Heart Association, the American Red Cross, the American Safety and Health Institute, the Canadian Red Cross, the Emergency Care and Safety Institute, Emergency First Response, Emergency Medical Training Associates, the Emergency University, EMS Safety Services, Medic First Aid, the Military Training Network, the National Safety Council, and ProCPR.

Step 4: Apply for the DANB CDA exam (timelines vary)

The cost of DANB’s CDA exam is $450. This breakdown of exam eligibility requirements describes varied pathways and how to apply for the certifications. Aspiring dental assistants can use the CDA Application Packet to determine whether they would like to apply digitally, via mail, or by fax.

The DALE Foundation, the only official affiliate organization of the DANB, hosts study aids, review courses, and practice exams. These include a CDA exam outline, the CDA application packet, and a list of relevant areas to study. DALE boasts extensive study aids for all three CDA exams, including reviews and practice tests for the RHS, ICE, and GC areas of expertise. The DANB RHS Review, along with the DANB ICE Review and parts one and two of the DANB GC Review, cost $130 per course.

Step 5: Pass the DANB CDA exam (six to eight weeks)

Certification and licensure requirements for the CDA exam can differ from state to state, but the DANB has curricular authority in all 50 states. In the 39 of these states where certification is necessary, the three exams that constitute the DANB certification total 320 questions.

Pearson Inc.’s VUE testing centers host the tests. As mentioned above, there are three individual exams required to receive a CDA certification through the DANB, which include the General Chairside Assisting (GC) exam, the Radiation Health and Safety (RHS) exam, and the Infection Control (ICE) exam. The test has a possible 900 points; a passing score is 400.

Again, the DANB offers various dental assistant certifications. These include the National Entry Level Dental Assistant (NELDA) certification, the Certified Preventive Functions Dental Assistant (CPFDA) certification, and the Certified Restorative Functions Dental Assistant (CRFDA) certification. A general CDA certification or a certified orthodontic assistant (COA) certification is also available.

These certifications specialize in periodontics, endodontics, prosthodontics, pediatric dentistry, dentofacial orthodontics, and maxillofacial surgery. Digital imaging techniques, advanced radiography, diet and nutrition for oral health, and dental care for infants are just a few of the other areas one might be interested in studying.

CDAs who have obtained certification through the DANB must stay current on industry standards and re-certify their credentials each year through continuing dental education courses.

Step 6: Get an entry-level CDA position (timeline varies)

As demand for dental assistants is high, graduates should find no shortage of available jobs in any of the positions or specializations listed above. Between 2021 and 2031, dental assistant positions are expected to grow by 8 percent, faster than the national average for all occupations at 5 percent (BLS May 2022). By 2031, the BLS projects that almost 56,400 new CDA positions will be added to the American market.

Dentistry-centric job boards such as the one operated by the American Dental Assistants Association (requires membership), (requires membership), or host job listings for dental professionals of all walks and degree levels.
