What Does a Dental Assistant Do?
Between patients, a dental assistant runs instruments through the autoclave, wipes down the chair and sets out a fresh tray. Most dental assistants work in private offices, with others in dental school clinics, hospitals and community health centers, where they pass instruments, handle suction and take X-rays. Many states also let them polish teeth or apply sealants.
Dental Assistant Duties and Responsibilities
The primary responsibilities of a dental assistant include:
- Seat patients, review health history updates and explain what the visit will involve.
- Pass instruments and use suction to keep the working area clear during procedures.
- Take and process dental X-rays following state radiation safety rules.
- Clean, bag and sterilize instruments in the autoclave and log each cycle.
- Prepare fillings, impression materials and temporary crowns as the dentist directs.
- Disinfect treatment rooms between patients and restock trays and supplies.
- Record treatment notes and charting in dental software such as Dentrix or Eaglesoft.
- Teach patients brushing, flossing and aftercare for extractions or new appliances.
- Schedule follow-up visits and help with billing and insurance questions at the front desk.
