What Do Dental Assistants in North Dakota Do?

A great dental team has a skilled and knowledgeable dentist and reliable and wise dental assistants. Dental assistants not only help around the office, clean teeth, take radiographs, but they also directly help in dental operations such as filling cavities, placing crowns, and more. This post will go more in-depth to dental assisting duties. Keep in mind, duties for dental assistants do vary from office to office in North Dakota.


After a patient leaves, it is the dental assistant’s job to clean the room and prepare for the next patient. First, you’ll remove all of the used hand pieces and instruments. Typically, you will take these to the sterilization room in the office to be sterilized for future use. Then you’ll return to the room to wipe down the dental chair, light, counter, and anywhere else that has been exposed to the previous patient. After the room is clean, you’ll set up the next room for the next patient. What instruments and materials you set out will depend on what procedure is planned for the next patient. You’ll learn how to set up rooms to your dentist’s specifications and for each procedure through your education and in-office training.


To take radiographs as a dental assistant in North Dakota, you will need to be Registered Dental Assistant (RDA) or a Qualified Dental Assistant (QDA). To become a RDA, you must pass the Dental Assistant National Board’s (DANB) Certified Dental Assistant or the CODA-accredited or North Dakota board-approved dental assisting program, pass a written exam, and register with the North Dakota State Board of Dental Examiners (NDSBDE). To become a QDA, you must pass the DANB’s Radiation Health and Safety (RHS), the Infection Control exam (ICE), maintain a CPR certification, and log 650 hours on the job. After the 650 hours are complete, submit your application to the North Dakota State Board of Dental Examiners. Dental assistants are still trained in-office to take radiographs because it does take some skill and safety precautions to take them correctly.

Since Radiographs do expose the human body to slight amounts of radiation, typically dental assistants will limit their exposure by setting up the radiograph and activating the sensor a few feet away from the patient. In some dental offices, pregnant dental assistants are not to take radiographs. If you do have concerns about taking radiographs regularly, most dental offices will accommodate you, but there really is not much to worry about with the limited exposure.


Dental assistants will bring the patient back and prepare them for the dentist’s exam. Dental assistants prepare the patient’s teeth by cleaning them through a special procedure called a “Prophylaxis,” or “Prophy” for short. They’ll use a special type of toothpaste and a spinning handpiece that resembles a toothbrush, but it’s topped with a “prophy cup.” After cleaning their teeth, dental assistants will then floss the patient’s teeth. The dentist then arrives to examine the teeth for cavities, abnormalities, and more. Dental assistants often notate the condition of the patient’s teeth, jaw, and gums in the patient’s chart.


The best dental assistants can predict the dentist’s next move. If the dental assistant knows the procedure well, they’ll be ready to hand off the next instrument or material used quickly. Memorizing new procedures takes time, but after learning what materials will prep teeth and what instruments are used for what, dental assistants instinctively will know what to hand the dentist next.
