Most Australians have never seen this data
The Australian Institute of Health and Welfare publishes comprehensive national oral health statistics that are genuinely surprising when you read them. Here is what the data actually shows, and what it means for your dental health decisions.
The headline numbers
The AIHW's 2022 report presents a picture of widespread disease alongside significant access barriers. Tooth decay remains the most common chronic disease in Australia. Over half of Australian children aged 6 have experienced decay in their baby teeth. Periodontal disease affects approximately 22.9% of Australian adults with moderate to severe disease. Three in ten Australian adults report avoiding the dentist because of cost.
The decay data
By age 12, Australian children had an average of 1.7 decayed, missing or filled permanent teeth. Among adults, approximately 32% had untreated tooth decay at any given time.
The inequality dimension
Higher rates of disease and lower rates of attendance are consistently seen in lower socioeconomic groups, Aboriginal and Torres Strait Islander Australians, people in regional and remote areas, and adults without private health insurance.
What Australians spend
The AIHW estimates total spending on dental services at over $11 billion annually, with the majority from out-of-pocket patient payments. The Medicare system does not cover routine adult dental care. The Child Dental Benefits Schedule provides partial coverage for eligible children.
The systemic connection
Periodontal disease is associated with increased cardiovascular risk, poorer glycaemic control in diabetic patients, and adverse pregnancy outcomes. Oral health is not a cosmetic issue separate from general health.
What this means practically
Dental disease at the population level is largely preventable with regular professional care and consistent home hygiene. The cost of avoidance consistently exceeds the cost of prevention.
