Job Description of Dental Assistants: Dental assistants provide different types of patient care, office duties, and laboratory duties. They do not perform the same tasks that dental hygienists are licensed to perform.
Employment Facts About Dental Assistants: Dental assistants held about 267,000 jobs in 2004. Most worked in dentist's offices while others worked in physicians' offices, educational services, and hospitals. About one-third of all dental assistants worked part-time, sometimes working for more than one dental practice.
Educational Requirements for Dental Assistants: Dental assistants usually learn their skills on the job, although some receive training from dental-assisting programs offered by community and junior colleges, trade schools, technical institutes, or the Armed Forces. High school students interested in a future career as a dental assistant should take courses in biology, chemistry, health, and office practices.
Other Requirements for Dental Assistants: Dental assistants must be reliable, work well with others, and have good manual dexterity. In some states, dental assistants must be licensed or registered. They may be required to pass a written or practical exam. Dental assistants who perform specialized duties, such as radiological procedures, may have to complete the Radiation Health and Safety examination offered by the Dental Assisting National Board (DANB). In a few states, they may also have to pass a state-approved course in radiology.
Advancement for Dental Assistants: Some dental assistants become office managers, dental-assisting instructors, or dental product sales representatives, but opportunities are limited for those without further education. Some dental assistants become dental hygienists after going back to school.

The Bureau of Labor Statistics predicts that it will be the third fastest growing occupation for which a degree isn't required.
