Dental Assistant vs. Hygienist

When it comes time to visit a dental clinic, most patients expect to have their teeth examined by a dentist. However, the majority of the time spent at a dentists’ office is in the care of dental assistants and hygienists. While dental assistants and hygienists both care for the needs of dental patients, these two careers have distinctive duties as well as educational and licensure pathways.

Dental assistants perform a wide range of dental and administrative patient care duties. They handle the logistics of a dental patient’s visit through leading patients to examination chairs, ensuring patient comfort, preparation and sterilization of dental instruments, processing x-rays and laboratory tasks, educating patients on healthy oral hygiene practices, scheduling follow-up appointments, and handling billing and payment requests. In some states, dental assistants are allowed to perform limited dental procedures such as coronal polishing, and application of sealants, fluoride, and topical anesthetic.

By comparison, dental hygienists are largely responsible for cleaning teeth, examining patients for oral diseases, and educating patients on preventative dental care practices. They use many types of specialized dental tools to perform their job including hand, power, and ultrasonic tools. Dental hygienists take x-rays of patients’ mouths to check for problems with teeth or jaw alignment. They remove tartar, stains, and plaque from patients’ teeth, apply sealant and fluoride treatments, complete oral health assessments and report their findings to dentists, take documentation notes about patient care and treatment plans, educate patients on how to select oral care devices, and how to properly brush and floss teeth for patients’ optimum dental health.

Educational and certification requirements differ for dental assistants and dental hygienists and individual states have unique career pathways. Dental assistant requirements vary the most; some states require no formal education in lieu of on the job training while other states require students to graduate from a one or two-year dental assistant vocational program accredited by the Commission on Dental Accreditation (CODA), an organization associated with the American Dental Association (ADA). Some states require dental assistants to earn nationally-recognized certification through the Dental Assisting National Board (DANB).

Dental hygienists are typically required to earn an associate’s degree in dental hygiene and more than 300 dental hygiene programs are accredited through CODA. Associate’s degree programs in dental hygiene typically take three years to complete and include courses such as anatomy and physiology, nutrition, radiography, pathology, medical ethics, and patient management. Bachelor’s and master’s degrees are less common and only required for dental hygienists desiring to focus on research, teaching, or clinical practice in public dental health programs.

Laboratory and clinical courses give dental hygiene students hands-on experience in addition to classroom instruction. Every state requires dental hygienists to be licensed and requirements for each state are set forth by individual state’s board of dental examiners.

While dental assistants and hygienists have unique sets of educational backgrounds and responsibilities, the two professions also share some similarities. In order to effectively care for the needs of dental patients, both dental assistants and dental hygienists must possess specialized dental knowledge and certain skills including detail-orientedness, interpersonal skills, hand dexterity, and high verbal communication skills.

Most dental clinics also require dental assistants and hygienists to maintain current cardiopulmonary resuscitation (CPR) certification. Both careers are experiencing a higher than average rate of national growth; data from the U.S. Bureau of Labor Statistics (BLS 2021) predicts a rate of 11 percent growth for dental assistants and an 11 percent rate of growth for dental hygienists between the years 2020 and 2030, meaning 36,900 and 23,100 new jobs will be created in each respective field.

Read on to explore the unique professional, educational, and licensure differences between dental assistants and dental hygienists.

The Bottom Line

Dental assistants provide dental and administrative care for patients and assist dental hygienists and dentists with clinical procedures.

They have contact with patients from the moment they walk into the door, ensuring patient comfort, setting up the room for dental procedures, sterilizing equipment, and handing tools to dentists or dental hygienists during a patient procedure. Some states allow dental assistants to perform basic dental procedures.

Dental assistants handle administrative tasks such as appointment scheduling and billing and payment questions.

Dental hygienists’ responsibilities are largely centered on patient care. They clean and polish teeth, perform examinations to identify and prevent oral diseases such as gingivitis and do basic oral cancer screenings.

They are responsible for assessing patients’ overall oral health and delivering oral summaries to a dentist prior to examination.

Dental hygienists advise patients on what types of oral health tools are best for their individual needs, and educate patients on proper brushing and flossing homecare techniques to promote good oral health practices.
