Is a Dental Assistant License Required in California?

If you’re considering a career in dental assisting, you’re likely wondering about the licensing requirements. Dental assistants play a crucial role in oral health care, offering support to dentists and enhancing patient experiences. But do you need a license to start working in this field, and how can licensing impact your career trajectory?

Understanding the licensing and certification requirements, especially in California, can help you make informed decisions and set the path for a successful career. This guide will explain everything you need to know, from unlicensed roles to advanced certifications like Registered Dental Assistants with Expanded Functions (RDAEF).

What Is a Dental Assistant?

Dental assistants are vital members of any dental team. They work alongside dentists to ensure a smooth workflow and provide patients with the best care possible. But not all dental assistants perform the same duties—their roles vary depending on their level of training, certification, and licensure. Here’s a breakdown:

  • Unlicensed Dental Assistants: Perform basic tasks such as sterilizing instruments, seating patients, and managing administrative duties under the dentist’s supervision.  
  • Registered Dental Assistants (RDA): Have additional training and state licensure, enabling them to perform advanced tasks like taking X-rays, applying fluoride, and assisting in more complex procedures.  
  • RDAEF (Registered Dental Assistant in Expanded Functions): These professionals require even more training and certifications, allowing them to take on specialized duties like placing restorations and performing procedures under the dentist’s indirect supervision.

Each role comes with unique responsibilities, which are determined by licensing requirements and the scope of practice allowed by California's regulations.

Do You Need a License to Be a Dental Assistant in California?

The Short Answer

Not necessarily. Entry-level dental assistants in California can start without a license, but certain certifications and licenses are mandatory for performing specific tasks.

Unlicensed Dental Assistants

Unlicensed dental assistants can get started immediately and work under a dentist’s supervision. However, to remain compliant with California law, unlicensed assistants are required to complete the following within 120 days of employment:

  • California Dental Practice Act course  
  • Basic Infection Control course  
  • CPR certification from an approved provider  

These ensure adherence to safety and legal standards.

Registered Dental Assistants (RDA)

To perform more advanced duties (such as taking X-rays or applying sealants), you’ll need to become an RDA. This requires:

  • Completing a Dental Board of California-approved educational program  
  • Obtaining CPR certification  
  • Passing the RDA written and practical exams  
  • Submitting Live Scan fingerprints and passing a background check  

Once licensed, RDAs can access higher-paying roles and additional job opportunities in the dental field.

  • Have an active RDA license  
  • Complete additional coursework in expanded duties  
  • Pass the RDAEF state exam and obtain licensure  

RDAEFs are highly trained professionals, and their expertise often commands higher salaries.
