Dental Assistant

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 follow up 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.
