Dental Hygienist

Dental hygienists work as part of the dental team in treating patients. They use preventive, educational and therapeutic methods for the control of oral diseases to aid individual patients and groups in achieving and maintaining oral health. They are trained to do specific clinical procedures which aim to prevent dental disease and work under the supervision of a dentist.

There is currently a shortage of hygienists due mainly to the shortage of training facilities and places are limited in Australia, thus competition for this dental career is keen.


  • What is a dental hygienist?

    A dental hygienist is a registered primary healthcare professional who provides highly skilled preventive services on all age groups without cutting or removing teeth. As a clinician they work in collaboration with a dentist to determine therapeutic treatment for each individual patient, but work independently in delivering their dental services. They work within a team environment to assure best practice in providing safe and appropriate dental healthcare.

    A dental hygienist career would be a good dentistry position for you if you have good time management (efficient), apply attention to detail and precision (accurate) and possess good hand-eye coordination and manual dexterity. In addition, if you find being a good listener with sensitivity to the needs of others as personally rewarding, you have some of the qualities that make you well suited to be a dental hygienist.

  • What do dental hygienists do?

    A dental hygienist’s clinical role includes a variety of duties that are focused on diagnostic, therapeutic and preventive duties to support total health for the control of oral diseases. The Dental Act in each state regulates the procedures that a dental hygienist can perform.

    As part of dental hygiene services, a dental hygienist career in New South Wales may include:
    • Perform oral health assessments that include taking a health history, dental charting, oral cancer screening, saliva testing and taking vital signs (blood pressure, pulse, blood glucose, respiration);
    • Expose, process and interpret dental X-rays;
    • Make impressions of the teeth for plaster study models and mouthguard construction;
    • Photograph exterior and interior oral structures to profile stages of treatment and outcomes;
    • Administer anaesthetic injections to numb the teeth and gums;
    • Remove plaque, calculus (soft and hard deposits) and stain from above and below the gum line;
    • Polish the teeth and dental restorations;
    • Perform root planing for non-surgical periodontal therapy;
    • Place and remove a post-surgical dressing and remove sutures;
    • Select and size orthodontic bands, prepare teeth for placement of braces and remove wires and fixed orthodontic appliances;
    • Apply decay preventive agents such as fluorides, varnishes and sealants to the teeth;
    • Teach oral hygiene techniques to help people maintain healthy teeth and gums; and
    • Counsel patients on plaque control, good nutrition, smoking cessation and systemic health.

    Dental hygienists use their knowledge and clinical skills to provide dental hygiene care and their interpersonal skills to motivate and instruct patients on methods tailored to preventing oral disease and maintaining oral health.

    A dental hygienist must practice under legislative regulations much like other registered health professionals such as nurses, dentists, physicians, pharmacists, physical therapists, optometrists, osteopaths, chiropractors and psychologists. Registration to practice a dental hygienist job requires proof of successful completion of an accredited dental hygiene diploma or university degree evidenced by the state dental board and once granted must be renewed annually. Some states may require dental hygienists to participate in continuing education courses for the renewal of their registration. The process of registration represents the strongest form of protection for the public from unqualified individuals and unsafe practices.

  • Where do dental hygienists work?

    A dental hygiene profession offers women and men of all ages, races and ethnic backgrounds exceptional career opportunities to work as clinicians, educators, researchers, consumer advocates, sales and marketing managers, editors, authors and consultants in an array of flexible work schedules.

There is currently a strong demand for dental hygienists in both private and public sectors in regional and rural locations in most states of Australia, so considering a dental hygienist career would be a great idea.

This is a dental career avenue that can lead toward advanced degrees, such as a Masters degree or a PhD to qualify for a position as Professor.

Research is a component of advanced degrees and can be conducted in the dental clinic of a practice or training program, or within a laboratory setting. As well, dental hygiene faculties at universities may also be involved in oral health research.

    Consumer Advocate: Dental hygienists may come to concentrate their work on specific oral health implications that pertain to population-based issues such as diabetes, sleep apnoea, fluorides, childhood decay, etc. They stay well informed of the current research and activities to take on an active role of informing, educating and advising the public through health promotion using online, print, TV and radio media, as well an advisory role to the relevant government committees.

    Sales and Marketing Manager: Dental hygienists can be employed by product and service companies in the dental industry to lead both professional and public marketing campaigns. The work involves building customer relationships, identifying and presenting the market and the customer requirements as well as organising and participating in trade exhibitions.

    Editor/Author: Dental hygienists can apply their skills and knowledge toward informing and educating the dental profession on current issues, techniques and research. This position can involve a professional magazine, journal or textbook and requires writing skills, self-motivation, good organisational and time management skills (deadlines), attention to detail and creativity.

    Consultant: Dental hygienists that have achieved a level of clinical efficiency in time management that combines effective business and patient-centred principles can choose to share their achievements with dental professionals as a speaker delivering educational courses and/or advising the individual dental practice through onsite consultations. Additionally, dental hygienists can be employed by dental companies to create and deliver educational material to healthcare professionals and the public as an Educational Consultant.
