Australia’s shift to preventative dentistry and why it’s important

Our Oral Health Priorities are Changing

If we can shift our culture away from crisis care and towards prevention, oral health can become not just a reflection of health, but a foundation for it across every generation.

Our mouths are more than just a smile — they reflect our habits, stress and overall wellbeing. In Australia, the state of oral health is shifting as new generational trends emerge. Younger people face lifestyle risks that previous generations didn’t, parents are struggling to maintain consistent routines and older Australians are managing chronic health conditions that are often linked to oral disease.

Cost-of-living pressures are tightening access to preventive dental care, and the result is a widening divide between those who can stay ahead and those who fall behind. Furthermore, research has found that although 90 per cent of Australians understand there is a link between oral health and overall health, many people are still not making oral health a priority. In fact, only 6 per cent of Australians take their oral health more seriously than other aspects of health — even though we know there is a connection.

The Financial Barrier

For adults, cost is now one of the biggest disruptors of oral health. In 2022–23, 18 per cent of Australians reported delaying or skipping a dental visit because of expense. Preventive care is often sidelined in favour of emergency treatment, turning small problems into major interventions and reinforcing the idea that the dentist is a last resort. This crisis-care model of dentistry is deeply embedded and difficult to reverse.

The financial divide has grown sharper in recent years. Families facing rising rents, mortgages and grocery bills are more likely to defer check-ups or hygiene visits. At the same time, people with disposable income are investing more heavily in aesthetic dentistry — clear aligners, veneers, whitening — creating a stark contrast between those who can access comprehensive care and those who only seek treatment when in pain.

Generation Gaps

As Australians grow older, the consequences become more systemic. Gum disease is common in over half of those aged 55 to 74, and in nearly 70 per cent of people over 75. Bacteria from the gums can enter the bloodstream and contribute to the narrowing of blood vessels, raising the risk of heart attacks. People with gum disease are twice as likely to develop heart disease. In those with diabetes, treating gum disease can modestly improve blood sugar control, supporting better outcomes overall.

Many older Australians take multiple medications daily for different conditions and a common side effect of this is dry mouth, which reduces saliva’s natural protective function and accelerates tooth decay and gum problems. This creates a cycle where oral health directly affects nutrition and systemic health, yet is often deprioritised in aged care settings.

Modern Risks: Gen Z and Social Media

Younger generations, particularly Gen Z and millennials, are navigating a unique set of risks. Daily habits such as energy-drink consumption and constant grazing — whether sipping kombucha, coffee or snacking while working from home — keep the mouth in a state of repeated acid exposure.

At the same time, social media platforms fuel unsafe “dental hacks,” from filing teeth with nail files to whitening with lemon juice or charcoal powders. These trends may create short-term cosmetic effects, but the long-term damage — irreversible enamel loss and sensitivity — is significant. This shortcut culture reflects a generational shift where appearance is prioritised over health.

The Parent Trap

Research shows that one in four children regularly skip brushing, most commonly due to “everyday chaos.” Data suggests that 32 per cent of children brush only once a day, while more than 75 per cent rarely floss. By the age of ten, 42 per cent of Australian children have experienced decay in their baby teeth. These early patterns tend to follow people throughout life.

Best Oral Health Practices

So, what do best practices actually look like?

• For children (18 months to 5 years): Use a small, pea-sized amount of low-fluoride toothpaste under adult supervision.

• From age 6: Brush twice a day with fluoride toothpaste. Importantly, children should be taught to spit but not rinse.

• Interdental Cleaning: Daily use of floss or interdental brushes reduces gum inflammation and supports overall hygiene.

• Adult Care: Busy adults should take bleeding gums seriously as an early warning sign of disease.

The Role of Technology and Mental Health

Technology offers hope for building better habits. Smart toothbrushes with timers and apps can gamify oral care for children and provide real-time feedback for adults. Another under-acknowledged area is mental health. Stress and anxiety contribute to grinding and jaw pain, while depression can make daily routines feel overwhelming. This shows just how closely oral health connects with broader wellbeing.

A Holistic Future

Your smile is a gateway to your overall health. Whether it’s a daily brush or booking a twice-yearly check-up, small, consistent steps can protect your wellbeing for years to come. If we can shift our culture away from crisis care and towards prevention, oral health can become a foundation for health across every generation.
