Australia is the top-ranking country for equity and healthcare among Organisation for Economic Cooperation and Development (OECD) nations, and ranks third for overall healthcare system effectiveness, behind Norway and the Netherlands [2]. Yet despite these strong outcomes, oral health, particularly periodontal disease, remains a widespread “silent epidemic.”
Before diving deeper into current findings, it’s important to understand how this report was put together. This report explores the issue using the latest data from the Australian Institute of Health and Welfare (AIHW) and is medically reviewed by the principal dentist at Aesthetic Dental Clinic.
Key Findings: The State of Gum Health in Australia
Periodontitis is a common oral health condition in Australia, with around 3 in every 10 adults suffering from moderate to severe gum disease [1]. Early assessment and professional gum disease treatments can reverse gum disease, but if left untreated, it can lead to serious oral health issues.
Here are some of the latest statistics of gum health in Australia:
- Around 29% (3 out of 10) adults aged 15 years and over had gingivitis [3].
- About 30% of adults aged 15 years and over had moderate to severe periodontitis [3].
- The proportion of adults suffering from moderate to severe gum disease increases with age, with 12% in 15 to 34 year olds, 33% in 35 to 54 year olds, 51% in 55 to 74 year olds, and 69% in 75 year and older [3].
- The number of adults with complete tooth loss increases with age: 1.1% in 35 to 54-year-olds, 8.1% in 55 to 74-year-olds, and 21% in 75-year-olds and older [3].
- Adults without dental insurance were more likely to have complete tooth loss compared to those with dental insurance [3].
- Gum disease can affect overall health. There is increasing evidence that it is linked to heart disease, diabetes, lung conditions, stroke, and mouth cancer [1].
Gingivitis vs. Periodontitis: Understanding the Numbers
Gingivitis is often used interchangeably with periodontitis, but the two are separate conditions with different levels of severity.
Gingivitis
Gingivitis is the earliest stage of gum disease, affecting the superficial gum tissues along the gum line [4]. Recent data show that 29% of adults aged 15 years and older have experienced gingivitis. The breakdown by gender reveals that 35% of males and 23% of females have had gingivitis. Additionally, 22% of children aged 5 to 14 years have had gingivitis [3].
Periodontitis
Periodontitis is a more serious stage of gum disease, usually the result of untreated gingivitis. It is the inflammation of the deeper gum layers or the periodontium, the structures that keep the teeth in their place.
The periodontium is protected by the gums, creating a seal around each tooth. But if this seal is damaged, spaces form between the gum and tooth roots, creating the perfect place to trap bacteria. Eventually, these spaces lead to permanent bone loss [4]. The latest data reveals 30% of Australian adults have had moderate to severe periodontitis [5].
Demographics: Who Are Most Affected?
Gum disease is prevalent across age groups, communities, and lifestyles, affecting both males and females. Let’s examine the statistics.
Age and Gender Disparities
Age
The number of adults suffering from moderate to severe periodontitis increased with age.
- 12% in those 15 to 34 years old
- 33% in those 35 to 54 years old
- 51% in those aged 55 to 74 years old
- 69% in those 75 years old and older [3]
Gender
- Males 35%
- Females 26% [3]
Lifestyle Risk Factors
- Around 32% of moderate to severe periodontitis in Australia is due to smoking [6].
- The University of Adelaide reported a clear relationship between obesity and a higher risk of periodontal disease [7].
Other Factors
- Education: 45% of people who completed Year 10 or less have periodontitis, compared to 26% of those who completed Year 11 [3].
- Dental visits: Periodontal disease is 1.5 times more common among people who last visited their dentist for an issue (37%) than among those who went for a check-up (26%) [3].
- Eligibility for public dental care: 43% of eligible individuals have periodontitis, compared with 26% among those ineligible [3].
- Location: Queensland has the highest prevalence of periodontal disease among adults aged 15 years and older, at 37%, whereas South Australia has the lowest among states, at 21% [3].
The Systemic Connection: Gum Disease and Overall Health
Looking at current statistics on Australia’s oral health, there is a clear relationship between oral health and a person’s overall health. Severe gum disease is no longer just a dental issue but a condition that can affect broader medical outcomes. This is because chronic gum inflammation allows harmful bacteria to enter the bloodstream, which can eventually affect other tissues of the body.
Diabetes and Heart Disease
Studies show that there is a strong, two-way relationship between periodontal disease and Type 2 diabetes. People with diabetes are likely to develop moderate to severe gum disease. Meanwhile, people with untreated periodontal disease may find it harder to control their blood sugar levels. Also, inflammation from gum infections may contribute to the development and worsening of cardiovascular conditions [8].
Pregnancy and Other Health Issues
There is also emerging evidence that links severe gum disease to issues during pregnancy, which include preterm birth and low birth weight. Gum disease alone does not lead to these conditions, but ongoing inflammation and bacterial infection may increase the risk [9].
Understanding periodontal disease is not just about improving appearance or promoting fresh breath, but about protecting one’s overall health and wellness.
Frequently Asked Questions (FAQs)
How common is gum disease in Australia?
Gum disease affects around 30% of Australian adults and a higher number of people have early signs of gingivitis.
What is the leading cause of tooth loss in Australian adults?
Periodontal disease is one of the leading causes of tooth loss among Australian adults, as this disease destroys the tissues and bone that hold teeth in place.
Can gum disease be cured?
Early-stage gum disease, or gingivitis, is reversible with professional dental care, including dental cleanings and good oral hygiene. However, advanced cases of periodontitis can only be managed and halted, not treated.
What are the first signs of gum disease?
The earliest signs of gum disease include red, swollen, or tender gums that tend to bleed easily during flossing or brushing, along with persistent bad breath.
How often should I see a dentist to prevent gum disease?
The Australian Dental Association recommends a routine dental check-up every 6 to 12 months [10] for a thorough assessment and professional cleaning to monitor and prevent gum disease.
