When we think about heart disease, brushing and flossing might not come to mind, but research increasingly shows that your oral health may play a bigger role in heart health than you’d expect.
While more studies are underway to confirm the connection, current evidence suggests a strong link between gum disease and increased risk of heart problems. Here’s what we know so far, and why taking care of your teeth and gums might help protect your heart, too.
How Gum Disease Affects the Rest of the Body
Gum disease (gingivitis or periodontitis) is caused by bacteria that build up along the gumline. If left untreated, this bacteria can lead to inflammation, bleeding gums, and eventually damage to the bone and tissue supporting your teeth.
But that’s not where the effects stop.
The mouth is connected to the rest of your body through the bloodstream and digestive system. Harmful bacteria from infected gums can enter the bloodstream, travel to other areas, including the heart, and contribute to inflammation in blood vessels. This inflammation may lead to:
- The formation of small blood clots
- Narrowing or damage to arteries
- An increased risk of heart attacks and strokes
In fact, studies have found traces of oral bacteria in arteries affected by atherosclerosis, a condition where blood vessels become hardened or clogged.
Is It the Bacteria, or Your Body’s Reaction?
Some researchers believe it’s not just the bacteria themselves, but the immune response they trigger that creates further issues.
When bacteria enter the bloodstream, the body releases inflammatory proteins to fight them off. This chronic, low-grade inflammation may contribute not only to heart disease, but also to other serious conditions like dementia and diabetes.
Regardless of the exact mechanism, the takeaway is clear: keeping your mouth healthy helps reduce your risk of inflammation throughout the body.
How to Protect Your Heart with Better Oral Health
The good news? Oral hygiene is one of the easiest daily habits to maintain, and the benefits go far beyond your smile.
Here are a few key steps to follow:
- Brush your teeth twice a day, especially after breakfast and before bed
- Floss once daily to remove food particles and plaque between teeth
- Clean your gumline gently with your toothbrush to stimulate healthy gums
- Use interdental brushes or floss sticks if traditional floss is difficult
- Finish with a fluoride mouthwash to help rinse away lingering bacteria and leave your mouth feeling fresh
If it’s been a while since your last check-up, your dentist can assess your gum health and guide you on the best routine to follow.
A Healthy Mouth Supports a Healthy Body
Heart disease risk factors like smoking, poor diet, and lack of exercise are widely recognised, and oral hygiene could soon be added to that list.
By taking care of your teeth and gums now, you’re not just preventing cavities or bad breath, you’re investing in your long-term health and well-being. And as a bonus, a clean, healthy smile makes you feel more confident and comfortable in everyday life.
