Think gum disease is just your problem? Think again. Periodontal disease can be contagious, and you might be passing it on through everyday habits like kissing, sharing utensils, or even blowing on your toddler’s food.
This silent, progressive condition affects nearly 1 in 3 Australian adults and often goes unnoticed until it's advanced.
In this article, we will discuss how gum disease spreads, who’s at risk, and what you need to do now to protect your health and the health of those around you.
What Is Periodontal Disease?
Periodontal disease is an inflammatory condition affecting the gums and the supporting structures of the teeth. It starts as gingivitis, which causes red, swollen gums and bleeding when brushing.
If left untreated, it can progress to periodontitis, where the infection extends to deeper tissues and may result in tooth loss.
At BreezeCare, we’ve seen how early intervention and education can prevent long-term damage caused by this common dental condition.
So, Is Periodontal Disease Contagious?
Yes, periodontal disease is contagious to a degree, but not in the way that a cold or flu is. The bacteria responsible for gum disease can be transferred from person to person through the exchange of saliva. That means actions like:
-
Kissing
-
Sharing utensils or toothbrushes
-
Chewing food and feeding it to a child
-
Drinking from the same bottle or cup
…can allow the bacteria to pass between individuals.
However, developing gum disease also depends on your immune system, oral hygiene habits, and other health factors. Just being exposed to the bacteria doesn’t automatically mean you’ll develop periodontal disease.
How Does It Spread?
The bacteria that cause gum disease, such as Porphyromonas gingivalis, live in dental plaque, a sticky biofilm that forms on your teeth.
These bacteria can be passed between family members, romantic partners, or even from parent to child. That’s why we often see clusters of periodontal disease within households.
At BreezeCare, we always recommend that everyone in a household with a history of gum disease get their gums checked regularly.
Who’s Most at Risk?
While anyone can develop gum disease, you're more likely to be affected if you:
-
Have poor oral hygiene habits
-
Smoke or use tobacco
-
Have diabetes or other chronic conditions
-
Experience high levels of stress
-
Are you pregnant or have hormonal changes
-
Have a family history of gum disease
If your partner or family member has active gum disease, your risk increases, especially if oral hygiene is shared or overlooked.
How to Prevent the Spread of Gum Disease
Good oral hygiene and regular dental visits are your first line of defence. Here’s how to reduce your risk and protect your loved ones:
1. Don’t Share Saliva-Based Items
Avoid sharing toothbrushes, eating utensils, drinks or anything that involves contact with saliva.
2. Practice excellent Oral Hygiene
Brush twice daily, floss every day, and use an antibacterial mouthwash recommended by your dental professional.
3. Visit Your Dentist or Hygienist Regularly
Early signs of gum disease are often painless. Regular dental check-ups at Breezecare Oral Health help catch problems early and keep your gums healthy.
4. Avoid Smoking
Smoking weakens the immune system and increases the risk of gum disease and its severity.
5. Support the Oral Health of the Whole Family
Encourage everyone in your household to follow healthy dental habits and schedule routine check-ups.
How Is Periodontal Disease Treated?
Treating periodontal disease starts with targeting the root cause: harmful bacteria below the gum line. In its early stages, gum disease can often be reversed with professional cleaning and improved at-home care.
But once it progresses, more intensive treatment is needed to stop further damage, protect the teeth and gums, and prevent systemic health complications.
At BreezeCare, we take a personalised, science-backed approach to managing gum disease. Depending on the severity, your treatment plan may include:
-
Deep cleaning (scaling and root planing)
-
Antibacterial or antimicrobial mouth rinses
-
Tailored oral hygiene programs
-
Guidance on proper brushing and flossing techniques
-
Long-term maintenance and monitoring
If your condition is more advanced, we may refer you to a trusted periodontist for specialist care.
Final Thoughts: Protecting Yourself and Your Loved Ones
While periodontal disease can be contagious, the good news is that it's also highly preventable and manageable with the right care.
Being mindful of saliva transmission, practising excellent hygiene, and seeking regular dental care will go a long way in keeping your gums and your household healthy.
If you or someone close to you is showing signs of gum disease, don’t wait. Book a consultation with BreezeCare and take control of your oral health today.
