Why Infection Control Certification Is Legally Required for Dental Assistants in California
Infection control is one of the most important legal and safety requirements for dental assistants working in California.
The Dental Board of California requires dental assistants to complete a Board‑approved 8‑hour Infection Control certification course before performing procedures that involve exposure to blood, saliva, or contaminated instruments.
This requirement exists to protect patients, dental professionals, and the public from the spread of infectious diseases. Dental assistants play a critical role in maintaining a sterile and safe clinical environment, and proper infection control training ensures they understand the protocols necessary to prevent cross‑contamination.
Infection control certification training includes essential topics such as:
• instrument sterilization procedures
• prevention of cross‑contamination
• personal protective equipment (PPE)
• sterilization monitoring and documentation
• safe handling of contaminated instruments
• infection control standards under California regulations
Dental assistants who perform clinical duties without proper infection control certification are not only putting patients at risk, but they may also be operating outside of California Dental Board regulations.




Dental offices that allow untrained staff to perform clinical procedures can face serious consequences, including:
• Dental Board citations
• regulatory penalties
• increased liability exposure
• potential disciplinary action against the dentist
For this reason, holding a valid Infection Control certification is not optional — it is a legal and professional responsibility for dental assistants in California.
