Learn About Dental Assistant Certification

A dental assistant is known as a dentist’s second pair of hands. This is because they help provide quality oral healthcare by assisting during treatment and procedures.

Job Duties

Dental assistants work under a dentist’s supervision and perform a wide array of clinical and administrative duties based on employer, training, and state guidelines.

Clinical – Assistants are often responsible for removing sutures, taking and processing x-rays, preparing compounds used for making impressions, sterilizing dental equipment, and keeping a patient’s mouth dry by using a suction device.

Administrative – During a lull in treating patients or if the dentist is out of the office, dental assistants often handle administrative duties. They include billing patients, processing insurance claims, ordering dental supplies, and answering the telephone.
