What Does a Dental Assistant Do?

Dental assistants can be vital members of a dental office team. Dental assistant responsibilities can range from clinical tasks to clerical office work. They can help improve the efficiency of the practice by serving as an extra set of hands for the dentist, dental hygienist, and the front office manager. Dental assistants can also enjoy the satisfaction of helping patients by contributing to positive experiences at the dental office. U.S. News & World Report ranked dental assisting among the 30 Best Healthcare Support Jobs.^[1]

Dental Assistant Job Description

The majority of dental assistants (90%) work in dentists’ offices. The government and physicians’ offices employ another 4 percent of dental assistants. For the most part, dental assistants work full time. Some dental assistants work over the weekend and in the evening. ^[2] While their job responsibilities depend on the state and type of practice they work in, dental assistants typically perform a combination of clerical tasks in the front office and clinical duties in the back office. They work alongside dental hygienists and under the supervision of dentists.^[3][4]

Since dental assisting entails working closely with patients and handling medical instruments and equipment, these professionals wear safety gear to prevent the spread of infectious diseases: surgical masks, gloves, safety glasses, and protective clothing. Those who work with x-ray machines must also adhere to the appropriate safety procedures.^[5]
