Good oral health is fundamental to overall health and wellbeing (COAG 2015). Without it, a person’s general quality of life and the ability to eat, speak and socialise is compromised resulting in pain, discomfort and embarrassment.
Data on Australians’ oral health status and their use of dental services are limited as no comprehensive national data sources are available. The most complete information about Australians’ oral health status and their use of dental services is available via national population surveys.
Oral health status
Oral health refers to the condition of a person’s teeth and gums, as well as the health of the muscles and bones in their mouth. Poor oral health – mainly tooth decay, gum disease and tooth loss – affects many Australian children and adults (Table 1).
A key indicator of the oral health status of a population is the dental caries experience, that is, having a dmft (for the primary dentition) or DMFT (for the permanent dentition) score greater than zero. The dmft or DMFT score counts the number of teeth that are decayed, missing or filled because of caries. Refer to Key terms in Healthy teeth.
Untreated tooth decay reflects both the prevalence of dental decay in the population and access to dental care for treatment.

Dental professionals provide preventive, diagnostic and restorative dental services. They can include dentists, dental prosthetists, dental hygienists, oral health therapists and dental therapists (Dental Board of Australia 2018). All dental professionals must be registered to practise in Australia. There were around 24,600 registered dental practitioners in Australia in 2020.
Dental services are funded, and can be accessed, in a number of ways – privately or through public dental clinics or the Department of Veterans Affairs (based on eligibility). For those who purchased services privately, some may have had all or part of the costs of the service subsidised. In 2021–22:
- 44.8 million dental services were subsidised by private health insurance providers (APRA 2022) – for more information refer to chapter on Private health insurance.
- 4.7 million services were subsidised under the Australian Government’s Child Dental Benefits Schedule (Services Australia 2023) which supports provision of basic dental services to eligible children aged 2–17. For more information refer to the section on Child Dental Benefits Schedule.
A dental visit can provide an opportunity for the provision of preventive dental care to maintain existing oral health, as well as treatment services that may reverse disease or rehabilitate the teeth and gums after damage occurs.
The National Child Oral Health Study 2012–14 (Brennan et al. 2016) found that for children aged 5–14, it was estimated that:
- Most (57%) had made their first dental visit before the age of 5
- The majority (87%) first visited a dental professional for a check-up (rather than for a problem)
- The majority (81%) had last visited a dental professional in the 12 months prior to the survey and most (57%) had last visited a private dental service
- 1 in 9 (11%) had never visited a dental provider
- The proportion of children who last visited a dental professional for a check-up (which reflects a favourable visiting pattern) varied by household income. Nearly 9 in 10 children (88%) living in households with high income last visited the dentist for a check-up, compared with 7 in 10 children (71%) from households with low income.
The Patient Experience Survey 2021–22 (ABS 2022) found that for people aged 15 and over, it is estimated that:
- Nearly half (49%) visited a dental professional in the last 12 months
- Of those who needed to and saw a dental professional, the majority (57%) visited more than once in the last 12 months
- Around 1 in 10 (9.9%) people who saw a dental professional received public dental care
- Around 1 in 3 (33%) who needed to see a dental professional delayed seeing or did not see one at least once in the previous 12 months – and around 1 in 6 (16%) reported that cost was a reason for delaying or not seeing a dental professional.
For more information about dental visits refer to chapter on Dental care.
As well as visits to dental professionals, there were close to 83,000 hospitalisations for dental conditions that potentially could have been prevented with earlier treatment in 2020–21. The rate of potentially preventable hospitalisations for dental conditions was highest in those aged 5–9 years (10.9 per 1,000 population). For more information refer to chapter on Hospitalisations.
In 2020–21, around $11.1 billion was spent on dental services in Australia. The majority of this cost (around $6.5 billion, or 59%) was paid by patients directly, with individuals spending on average $253 on dental services over the 12-month period, not including premiums paid for private health insurance (AIHW 2022). Private health insurance providers financed around $2.2 billion (20%) of total expenditure for dental services (AIHW 2022). For more information refer to chapter on Costs.
Impact of COVID-19 on dental services
The COVID-19 pandemic has had an impact on both patients and dental professionals in terms of the number of services, type of services and the way in which services are delivered.
Early in the pandemic, the Australian Health Protection Principal Committee (AHPPC) issued advice to National Cabinet that recommended dental practices implement restrictions whereby dental professionals should only perform dental treatments that do not generate aerosols, or where treatment generating aerosols is limited and that all routine examinations and treatments should be deferred. These types of restrictions have been implemented and eased at various times over the course of the pandemic.
Events that may have impacted on service use over the period March 2020 to October 2021 across Australia, include:
- March 2020 – national lockdown introduced
- June 2020 – second wave of COVID-19 cases in Victoria
- August 2020 – Lockdown in Victoria
- October 2020 – Victorian lockdown eased
- December 2020 – outbreak of cases in Sydney’s Northern Beaches
- January to March 2021 – brief snap lockdowns in some states and territories to contain COVID-19 spread
- July to October 2021 – a series of extensive lockdowns and/or extended lockdowns in New South Wales, Victoria, and Australian Capital Territory.
In 2020–21, around 1 in 8 (12%) adults aged 15 years and over delayed seeing or did not see a dental professional at least once in the last 12 months due to COVID-19. For more information, refer to chapter on Patient experience.
