Gum Disease — Early Warning Signs, Treatment, and How to Prevent It

Gum disease is the leading cause of tooth loss in Australian adults. Not cavities — gum disease. According to the Australian Dental Association, roughly three in ten adults have moderate to severe periodontitis, and many do not know it because gum disease is often painless until it reaches an advanced stage.

The good news is that gum disease is almost entirely preventable, and in its early stages (gingivitis), it is completely reversible. The key is recognising the warning signs early and acting on them.

What Is Gum Disease?

Gum disease is a bacterial infection of the tissues that support your teeth — the gums, the ligaments, and the bone. It progresses through two main stages:

Stage 1: Gingivitis

Gingivitis is inflammation of the gums caused by plaque buildup at the gum line. It is the mild, reversible form of gum disease.

Signs of gingivitis:

Gums that bleed when you brush or floss (this is not normal — healthy gums do not bleed)
Red, swollen, or puffy gums (healthy gums are pale pink and firm)
Bad breath that does not go away with brushing
Gums that feel tender when touched

The important thing to know: Gingivitis causes no permanent damage. With improved brushing and flossing, plus a professional clean to remove built-up tartar, your gums can return to full health within two to three weeks.

Stage 2: Periodontitis

If gingivitis is not addressed, it can progress to periodontitis — a more serious infection that destroys the bone and ligaments supporting your teeth.

Signs of periodontitis:

Gums pulling away from teeth (recession), making teeth look longer
Deep pockets forming between teeth and gums
Teeth feeling loose or shifting position
Pus between teeth and gums
Changes in your bite or how your teeth fit together
Persistent bad breath or a bad taste in your mouth

Periodontitis is not reversible. The bone lost does not grow back on its own. Treatment can stop further damage and stabilise your teeth, but it cannot undo what has already been lost. This is why catching gum disease early — at the gingivitis stage — is so important.

Risk Factors

Some people are more susceptible to gum disease than others:

Smoking — the single biggest risk factor. Smokers are 2 to 3 times more likely to develop severe gum disease, and smoking masks symptoms (smokers’ gums bleed less, hiding early warning signs)
Diabetes — poorly controlled blood sugar significantly increases gum disease risk. The relationship is bidirectional — gum disease also makes blood sugar harder to control
Genetics — some people are genetically more susceptible, even with good oral hygiene
Hormonal changes — pregnancy, puberty, and menopause can make gums more sensitive to plaque
Medications — some medications cause dry mouth (reduced saliva), which increases bacterial growth
Poor oral hygiene — inconsistent or ineffective brushing and flossing
Stress — impairs your immune system’s ability to fight infection
Age — risk increases with age, partly because of cumulative exposure and partly because of changes in immune function

How Gum Disease Is Treated

Gingivitis Treatment

Professional scale and clean — your dentist or hygienist removes tartar (hardened plaque) above and below the gum line that you cannot remove at home
Improved home care — we will review your brushing and flossing technique and recommend specific tools (interdental brushes, electric toothbrush) based on your situation
Follow-up — usually a review appointment in 4 to 6 weeks to check gums are responding

Most patients see significant improvement within 2 to 3 weeks of consistent care.

Periodontitis Treatment

Deep cleaning (scaling and root planing) — a more thorough cleaning performed under local anaesthetic, reaching deep below the gum line to remove bacteria and smooth the root surfaces so gums can reattach
Antibiotics — in some cases, antibiotics (either local or systemic) are used alongside deep cleaning to eliminate persistent infection
Ongoing maintenance — patients with periodontitis typically need professional cleaning every 3 to 4 months rather than every 6 months, to prevent recurrence
Surgery (severe cases) — if pockets are too deep to clean non-surgically, gum surgery may be needed to reduce pocket depth, regenerate bone, or graft tissue

The Connection Between Gum Disease and General Health

Research increasingly shows links between gum disease and broader health conditions:

Heart disease — people with gum disease have a higher risk of cardiovascular disease. The bacteria from infected gums can enter the bloodstream and contribute to arterial inflammation
Diabetes — the relationship goes both ways. Gum disease makes diabetes harder to control, and uncontrolled diabetes worsens gum disease
Respiratory infections — bacteria from the mouth can be inhaled into the lungs, potentially causing or worsening pneumonia and other respiratory conditions
Pregnancy complications — periodontitis has been linked to premature birth and low birth weight

This does not mean gum disease causes these conditions, but treating gum disease can have positive effects on overall health.

How to Prevent Gum Disease

Prevention is straightforward:

Brush twice daily with a soft-bristled brush, angling bristles toward the gum line
Clean between teeth daily using floss, interdental brushes, or a water flosser
Have regular professional cleans — every 6 months for most people, every 3 to 4 months if you have a history of gum disease
Do not smoke — if you smoke, quitting is the single most impactful thing you can do for your gum health
Manage diabetes — work with your doctor to keep blood sugar well controlled
Do not ignore bleeding gums — this is an early warning sign, not something to normalise

Frequently Asked Questions

Is it normal for gums to bleed when brushing?

No. Bleeding gums are a sign of inflammation, almost always caused by plaque buildup. If your gums bleed when you brush or floss, do not stop — increase your flossing and brushing at the gum line, and book a dental check-up. The bleeding should reduce within one to two weeks of consistent care.

Can gum disease be cured?

Gingivitis (early gum disease) can be completely reversed with improved oral hygiene and professional cleaning. Periodontitis (advanced gum disease) cannot be reversed, but it can be stabilised and managed to prevent further bone loss and tooth loss.

How do I know if I have gum disease?

The early signs are bleeding when brushing or flossing, red or swollen gums, persistent bad breath, and gum tenderness. Advanced signs include receding gums, loose teeth, and pus. A dentist can diagnose gum disease by measuring the depth of the pockets between your teeth and gums.

My parents lost their teeth to gum disease — will I too?

Genetics play a role in susceptibility, but gum disease is not inevitable. Even if you are genetically predisposed, good oral hygiene and regular professional care can prevent or control gum disease. Being aware of your family history means you can be more proactive about prevention.

If your gums bleed, are swollen, or you have not had a professional clean in over a year, book a check-up. Early intervention is simple and painless — waiting makes it harder.
