What is a Dental Assistant?

A dental assistant is many things and it might just be the career for you. The Department of Labor predicts dental assisting to be amongst the fastest growing careers this decade. They are also expecting to see a continuing trend where trained and experienced dental assistants are being hired over those without formal training and/or experience. Take a look at our Career Outlook page for further career projections and employment data.

Dental assisting can be a great profession whether you plan to make a career out of it or use it as a stepping stone. You do not need any experience to begin your career as a dental assistant. If you are brand new to the field and just trying to get started, we can help you.

While many people are very happy being dental assistants throughout their careers, there are plenty of others who will begin their careers as dental assistants and later pursue other dental career options such as becoming a hygienist or even a dentist. Other dental careers include being a dental laboratory technician, an oral surgeon, a periodontist, or an orthodontist, just to name a few. Wherever your career takes you (and you don’t need to know exactly where you want to go right now), you’ll find that the field of dentistry is a diverse one that can offer you a wide variety of options and career paths.

Job Description

Dental assistants work in dental offices directly with patients and often alongside a dentist. While the specific function legally permitted for a dental assistant will vary by state and will depend upon credentialing, the tasks are still fairly consistent. Primarily they assist the doctor in all chairside procedures.

Additionally, they take dental images that are then read and interpreted by the doctor. Dental assistants can also prepare the materials necessary for impressions, restorations, and temporary fillings. New Jersey Registered Dental Assistants (RDA’s) can remove sutures, make temporary crowns and remove the excess cement used in placing crowns, place dental dams to isolate a tooth that a dentist may need to work on, and apply topical anesthesia and fluoride. Still other dental assistants may have laboratory duties such as pouring casts, cleaning and polishing appliances (such as retainers), and making temporary crowns. Dental assistants disinfect and sterilize instruments and equipment. They set up and prepare the materials, instruments, equipment, and anesthesia that the dentist will use to perform various procedures. Dental assistants work alongside dentists during procedures passing the instruments and materials, retracting (or pulling back a patient’s cheek), and suctioning saliva.

Dental assistants may also have clerical responsibilities such as updating dental records, entering diagnostic procedures, providing post-operative instructions, scheduling appointments, sending out bills, processing patient payments, maintaining inventory, and ordering needed dental supplies.

To be a good dental assistant you must be able to work well with others. You’ll interact with a variety of patients each day as well as different staff members. The ability to multitask is also useful. A typical day may start with escorting the patient to the treatment area where the sterile instrument pack was placed out, seating the patient, applying topical anesthesia, emotionally preparing a patient for an extraction, assisting the dentist with the actual procedure and charting the treatment that was performed.

A dental assistant should also be comfortable working in a healthcare setting where the potential for exposure to infection exists, where washing your hands and maintaining a clean workplace is expected, where gloves and masks are worn and where people may ask you questions about their health and safety.


Being a dental assistant should not be confused with being a dental hygienist.

A hygienist is the position you would likely be most familiar with when you personally visit the dentist to have your teeth cleaned. A career as a dental hygienist carries its own set of requirements and regulations, including an education of at least two years and as much as six years. Many people interested in dental hygiene will use dental assisting as a way to get their careers started and earn some money and experience while furthering their education.

If you are unsure about whether or not dental assisting is the career for you, we would encourage you to speak with people who are already in the field. A great place to start is at your own dentist’s office. Explain that you’re interested in a dental career and ask if you could sit down and talk with some of the staff regarding their thoughts about the field. Be sure to come prepared in advance with specific questions if you set up this type of informational interview. They are generously offering their time for you. It’s also a good idea to thank them and express your appreciation afterwards.

Educational Overview

While it is still possible in a limited number of offices to begin your dental assisting career without any experience or education and to be trained on the job, the majority of doctors and dental offices prefer to hire someone with training.

A high school diploma however is required to obtain a dental radiology license in NJ. Beyond high school, some vocational schools, community colleges, and private training programs such as Dental Assistant Services can provide you with the necessary and relevant education.
