Dental assistants should not be confused with dental hygienists, who are licensed to perform different clinical tasks. (See the statement on dental hygienists elsewhere in the Handbook.)
Dental assistants sterilize and disinfect instruments and equipment, prepare and lay out the instruments and materials required to treat each patient, and obtain patients’ dental records. Assistants make patients as comfortable as possible in the dental chair and prepare them for treatment. During dental procedures, assistants work alongside the dentist to provide assistance. They hand instruments and materials to dentists and keep patients’ mouths dry and clear by using suction or other devices. They also instruct patients on postoperative and general oral health care.
Dental assistants may prepare materials for impressions and restorations, take dental x rays, and process x-ray film as directed by a dentist. They also may remove sutures, apply topical anesthetics to gums or cavity-preventive agents to teeth, remove excess cement used in the filling process, and place rubber dams on the teeth to isolate them for individual treatment. Some States are expanding dental assistants’ duties to include tasks such as coronal polishing and restorative dentistry functions for those assistants that meet specific training and experience requirements.
Dental assistants with laboratory duties make casts of the teeth and mouth from impressions, clean and polish removable appliances, and make temporary crowns. Those with office duties schedule and confirm appointments, receive patients, keep treatment records, send bills, receive payments, and order dental supplies and materials.
Work environment. Dental assistants work in a well-lighted, clean environment. Their work area usually is near the dental chair so that they can arrange instruments, materials, and medication and hand them to the dentist when needed. Dental assistants must wear gloves, masks, eyewear, and protective clothing to protect themselves and their patients from infectious diseases. Assistants also follow safety procedures to minimize the risks associated with the use of x-ray machines.
About half of dental assistants have a 35- to 40-hour workweek. Most of the rest work part-time or have variable schedules. Depending on the hours of the dental office where they work, assistants may have to work on Saturdays or evenings. Some dental assistants hold multiple jobs by working at dental offices that are open on different days or scheduling their work at a second office around the hours they work at their primary office.
Training, Other Qualifications, and Advancement [About this section] Back to Top Back to Top
Many assistants learn their skills on the job, although an increasing number are trained in dental-assisting programs offered by community and junior colleges, trade schools, technical institutes, or the Armed Forces.
Education and training. High school students interested in a career as a dental assistant should take courses in biology, chemistry, health, and office practices. For those wishing to pursue further education, the Commission on Dental Accreditation within the American Dental Association (ADA) approved 269 dental-assisting training programs in 2006. Programs include classroom, laboratory, and preclinical instruction in dental-assisting skills and related theory. In addition, students gain practical experience in dental schools, clinics, or dental offices. Most programs take 1 year or less to complete and lead to a certificate or diploma. Two-year programs offered in community and junior colleges lead to an associate degree. All programs require a high school diploma or its equivalent, and some require science or computer-related...
