What Do Dental Assistants Do?

What does a dental assistant do?

According to the Bureau of Labor Statistics, dental assistants perform many tasks, ranging from patient care and taking X-rays to recordkeeping and scheduling appointments. Their duties vary by state and by the dentists’ offices where they work.

Duties

Dental assistants typically do the following:

  • Ensure that patients are comfortable in the dental chair
  • Prepare patients and the work area for treatments and procedures
  • Sterilize dental instruments
  • Hand instruments to dentists during procedures
  • Dry patients’ mouths using suction hoses and other equipment
  • Instruct patients in proper oral hygiene
  • Process X-rays and complete lab tasks, under the direction of a dentist
  • Keep records of dental treatments
  • Schedule patient appointments
  • Work with patients on billing and payment

Assistants who perform lab tasks, such as taking impressions of a patient’s teeth, work under the direction of a dentist. They may prepare materials for dental impressions or to create temporary crowns.

Dental assistants are allowed to perform the following procedures in some states:

  • Coronal polishing
  • Sealant application
  • Fluoride application
  • Topical anesthetic application

Coronal polishing, which means removing soft deposits such as plaque, gives teeth a cleaner appearance. In sealant application, a dental assistant paints a thin, plastic substance over teeth that seals out food particles and acid-producing bacteria to keep teeth from developing cavities. Fluoride application, in which fluoride is put directly on the teeth, is another anti-cavity measure. Some dental assistants may be qualified to apply local anesthetic to an area of a patient’s mouth, temporarily numbing the area to help prepare a patient for procedures.

Each state regulates the scope of practice for dental assistants.
