What does a dental hygienist do?

The answer to the question 'what does a dental hygienist do' is that they examine and clean patients' teeth. They typically offer preventative care to help patients to avoid oral diseases and they also teach patients about maintaining good oral health. Dental hygienists perform the following tasks:

Clean patients' teeth

Dental hygienists are responsible for cleaning patients' teeth and gums. They use ultrasonic devices to clean deeply and power polishing tools to eliminate stains. They may also use handheld implements to remove plaque and tartar. For some patients, a dental hygienist may provide a fluoride treatment to strengthen enamel and protect teeth from decay.

Examine patients' teeth

These dental professionals are responsible for examining patients' teeth and mouths to look for signs of oral diseases. When examining a patient's teeth, dental hygienists use tools to count teeth and study gums. If they find anything concerning or abnormal, dental hygienists consult dentists.

Monitor patients' oral health

Dental hygienists document the procedures they perform and the issues they discover. They review patients' dental histories during each visit to ensure that they're maintaining good oral health and following recommended treatment plans. This is especially important with younger patients, as their teeth are still developing. It can also be important for elderly patients, who may experience age-related changes in their dental health.

Teach patients about good oral health

Many dental hygienists advise patients on how to achieve better oral health by brushing and flossing their teeth regularly. They may offer advice and provide patients with educational pamphlets to review. Many dental hygienists also provide sample dental care items when needed, such as interdental brushes or floss.

Collaborate with dentists

Dental hygienists often work under the supervision of or in collaboration with a dentist. Some dentists allow dental hygienists to perform more tasks than others, depending on the preferences and specialisms of the dentist. This means that the role of a dental hygienist may vary according to the dentist with whom they work.

Benefits of being a dental hygienist

Working as a dental hygienist can be a rewarding career for many. Here are some of the benefits of being a dental hygienist:


Working as a dental hygienist can allow you flexibility in your working schedule as you're able to work full-time or part-time. Because dental hygienists perform non-emergency work, they can also keep predictable, regular working hours. Dental surgeries are usually open during normal business hours, with many offering shorter days on the weekend. Working these hours can help you to maintain a healthy work-life balance.

Dental hygienist work environment

Dental hygienists work in dentist offices and do much of their work in treatment rooms. When examining patients or cleaning their teeth, they typically sit in chairs or stools.

Because they may encounter infectious diseases, dental hygienists wear gloves, eyewear and face masks to protect themselves. They also follow safety protocols to guard both themselves and patients from radiation emitted from X-rays.

Dental hygienists may work standard office hours, or they may work weekends or evenings to accommodate patients' schedules. Most work part-time jobs, assisting dentists on select days each week. Those who are seeking full-time employment may have part-time jobs with more than one dentist.
