Dental assistants typically do the following:
- Ensure that patients are comfortable in the dental chair
- Prepare patients and the work area for treatments and procedures
- Sterilize dental instruments
- Hand instruments to dentists during procedures
- Dry patients’ mouths using suction hoses and other equipment
- Instruct patients in proper oral hygiene
- Process x rays and complete lab tasks, under the direction of a dentist
- Keep records of dental treatments
- Schedule patient appointments
- Work with patients on billing and payment
Dental assistants often spend much of their day working closely with patients and dentists. For example, dental assistants might take a patient’s medical history, blood pressure, and pulse before a procedure; explain what will be done; and talk to patients about oral care. They help dentists during a procedure by passing instruments and holding equipment such as suction hoses, matrix bands, and dental curing lights. Other tasks include preparing the treatment room and making sure that instruments and equipment are sterile. Dental assistants also may document the procedure that is done and schedule followup appointments.
Some dental assistants are specially trained to take x rays of teeth and the surrounding areas. They place a protective apron over patients’ chest and lap, position the x-ray machine, place the x-ray sensor or film in patients’ mouths, and take the x rays. Afterward, dental assistants ensure that the images are clear.
Assistants who perform lab tasks, such as taking impressions of a patient’s teeth, work under the direction of a dentist. They may prepare materials for dental impressions or temporary crowns.
Each state regulates the scope of practice for dental assistants. Some states let dental assistants polish teeth to remove stains and plaque from the enamel or apply sealants, fluoride, or topical anesthetic.
Detail oriented. Dental assistants must follow specific rules and protocols, such as infection control procedures, when helping dentists treat patients.
Dexterity. Dental assistants must be good at working with their hands. They generally work in tight spaces on a small part of the body, using precise tools and instruments.
Interpersonal skills. Dental assistants work closely with dentists. They also must be considerate in working with patients who are sensitive to pain or have a fear of undergoing dental treatment.
Listening skills. Dental assistants must pay attention to patients and other healthcare workers. They need to follow directions from a dentist or dental hygienist so they can help treat patients and do tasks, such as taking x rays.
Organizational skills. Dental assistants should have excellent organizational skills. They need to have the correct tools in place for a dentist or dental hygienist to use when treating a patient, and they need to maintain patient schedules and office records.

Some states require dental assistants to graduate from an accredited program and pass an exam. Most programs are offered by community colleges, although they also may be offered by vocational or technical schools.
Many dental assisting programs take about 1 year to complete and lead to a certificate or diploma. Programs that last 2 years are less common and lead to an associate’s degree. The Commission on Dental Accreditation (CODA), part of the American Dental Association, accredits about 250 dental assisting training programs.
Accredited programs include classroom and laboratory work. Students learn about teeth, gums, jaws, and other areas that dentists work on and the instruments that dentists use. These programs also include supervised practical experience.
High school students interested in a career as a dental assistant should take courses in anatomy, biology, and chemistry.
Dental assistants who do not have formal education in dental assisting may learn their duties through on-the-job training. In the office, a dental hygienist, dentist, or experienced dental assistant teaches the new assistant dental terminology, the names of the instruments, how to complete daily tasks, how to interact with patients, and other activities necessary to help keep the dental office running smoothly.
