- Occlusal X-rays: These X-rays show the chewing surfaces of the teeth.
Dental radiology certification programs typically cover the following topics:
- X-ray physics Radiation safety
- Dental radiographic anatomy
- Dental radiographic procedures
- Image interpretation
Dental radiology certification programs can be completed online or in person. The length of the program will vary, but most programs take between 12 and 24 months to complete.
The cost of dental radiology certification programs will vary depending on the program and the institution offering the program. However, most programs cost between $2,000 and $5,000.
Topics Covered in Dental Radiology Certification Programs
Dental radiology certification programs typically cover a variety of topics related to dental X-rays and radiation safety. Here are some of the common topics covered in these programs:
X-ray physics:
Understanding the principles of radiation, including the units of measurement and how radiation interacts with matter.
Radiation safety:
Learning how to minimize radiation exposure to patients, staff, and the general public. This includes proper use of lead aprons, thyroid collars, and other protective measures.
Dental radiographic anatomy:
Studying the structures of the teeth, jaw, and surrounding tissues as they appear on X-rays.
Intraoral and extraoral radiographic procedures:
Learning how to take different types of X-rays, including bitewings, periapicals, panoramic, and occlusal views.

How to Become Certified in Dental Radiology
To become certified in dental radiology, you must complete a program that is accredited by the American Dental Association (ADA). There are many different programs available, both online and in-person. The length of the program can vary, but most programs take between 12 and 24 months to complete.
Once you have completed an accredited program, you will be eligible to take the ADA's certification exam. This exam consists of 100 multiple-choice questions covering topics related to dental radiology. To pass the exam, you must score at least 75%.
- Register for a board-approved radiation safety course
- Complete 32 hours of training to learn how to take X-rays and understand them
- Undergo a written exam for the didactic piece and a practical exam for the lab and clinical part
- Physically practice performing dental X-rays on manikins
- Obtain an X-ray certification certificate that will remain valid indefinitely
- Learn everything you need to know about X-ray safety, setting up, taking, processing, and mounting X-rays for patients, radiation safety procedures of manikins and human subjects, proper techniques to handle digital and traditional X-rays, and dental definitions and terms.
Benefits of Dental Radiology Certification for Dental Assistants
Obtaining dental radiology certification can offer many benefits for dental assistants. Here are some of the advantages of getting certified:
Increased job opportunities:
Many employers prefer to hire dental assistants with certification in dental radiology.
Higher salary:
Certified dental assistants typically earn higher salaries than non-certified assistants.

If you are interested in pursuing dental radiology certification, I encourage you to start researching accredited programs and take the first step towards becoming certified.
Current guide: radiography credentials are jurisdiction specific
There is no single worldwide “dental radiology certification.” The legal pathway depends on the country, state or province where the assistant will work. Before enrolling, confirm the current rules with the relevant dental board, radiation authority or other regulator.
Verification checklist
- Identify the exact job title and radiographic duties permitted locally.
- Check minimum age, education, supervised training and practical competency requirements.
- Confirm whether a board-approved course, radiation-safety examination or national credential is accepted.
- Review dentist-supervision, operator-licensing, registration and renewal requirements.
- Retain certificates, continuing-education evidence and exposure/quality-assurance records required by the regulator.
In the United States, requirements differ by state. DANB’s Radiation Health and Safety (RHS) exam is recognised or required in many—but not all—states, so passing an exam does not automatically authorise radiography everywhere. Training should cover justification and prescription responsibilities, optimisation, patient identification, pregnancy enquiries according to local policy, positioning, image quality, retakes, infection control, equipment safety and incident reporting.
Frequently asked questions
Can any dental assistant take X-rays after an online course?
No. The course and pathway must satisfy the regulator governing the workplace.
Is DANB RHS accepted in every US state?
No. Recognition and additional requirements vary; verify the current state pathway.
Does certification allow an assistant to prescribe radiographs?
Not necessarily. Prescribing, justification and exposure duties are defined by local scope-of-practice rules.
Do radiography credentials expire?
Some require renewal, continuing education or registration; check the issuing authority.
What should international readers do?
Consult the national or regional dental and radiation regulator rather than applying US requirements.
