A registered dental assistant is a licensed professional who assists with general oral healthcare procedures and support in a dental office. A registered dental assistant is able to perform all of the duties of a certified dental assistant including preparing exam rooms, assisting dentists and hygienists during procedures and examinations, educating patients on oral health, providing patients with aftercare instructions, and scheduling appointments. They’re also able to perform expanded duties including taking x-rays and applying topical anesthesia. Registered dental assistants typically work in a clinical environment at a dental practice, a public health department, or in schools specializing in dental care.
