Dental assistants support dentists chairside, manage infection control and often handle office duties. They keep the practice running.
Duties
Preparing rooms, seating patients, assisting during procedures, sterilizing instruments, taking radiographs where credentialed and scheduling.
Settings
General practices, specialty offices, community clinics and hospitals.
Scope
Defined by state dental practice acts; expanded functions require additional training and credentials.
Common mistake
Assuming radiography or expanded functions are automatically allowed. Most states require specific certification.
A Day Chairside
A typical morning: arrive early to run sterilizer tests and set up the first three operatories, seat a hygiene patient and update their medical history, then assist the dentist through two composite fillings and a crown preparation, mixing impression material to the second, suctioning, passing instruments and keeping the field dry. Between patients you break down and disinfect the room, process instruments and confirm the afternoon schedule. The rhythm is fast and the assistant sets its pace.
