What do Dental Assistants Do?​


  • Ensure that patients are comfortable in the dental chair
  • Prepare patients and the work area for treatments and procedures
  • Sterilize dental instruments
  • Help dentists by handing them instruments during procedures
  • Keep patients’ mouths dry by 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.

All dental assistants complete certain tasks, such as helping dentists with procedures and keeping patient records. 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 anticavity measure. Some dental assistants may be qualified to apply topical anesthetic to an area of a patient’s mouth, temporarily numbing the area to help prepare a patient for procedures.



Career Outlook

According to the Bureau of Labor Statistics: ​“Employment of dental assistants is projected to grow 18 percent from 2014 to 2024, much faster than the average for all occupations. Ongoing research linking oral health and general health will likely continue to increase the demand for preventive dental services. Dentists will continue to hire more dental assistants to complete routine tasks, allowing the dentist to see more patients in their practice and spend their time on more complex procedures. As dental practices grow, more dental assistants will be needed. As the large baby-boom population ages, and as people keep more of their original teeth than did previous generations, the need to maintain and treat teeth will continue to increase the need for dental assistants.”


Earnings

The median annual wage for dental assistants was $35,980 in May 2015. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $24,950, and the highest 10 percent earned more than $50,660.
