The DANB Certified Dental Assistant (CDA) credential is the nationally recognized standard, though not all states require it. Radiology certification is commonly required to take dental X-rays. CPR certification is required in most states.

Expanded functions allow dental assistants to perform additional procedures beyond basic chairside duties. Some states require a separate Expanded Functions Dental Assistant (EFDA) credential, additional training, or specific coursework to perform these duties.
