How Healthy Gums Support a Healthy Heart by Our Teddington Dentists

February is National Heart Month in the UK, making it the perfect time to highlight one of the most important, but often overlooked, connections within the body: the link between your oral health and your heart.

At Church Road Dental Care Centre, we believe in looking after the whole patient, not just their smile. Growing research shows that the health of your gums may have a significant impact on your cardiovascular wellbeing.

In this article, our Teddington dentists explain the connection that can help you protect both your oral health and your overall health long-term. If you're concerned about any of the symptoms listed below, start by booking a check-up with our Church Road dentists.

The link between gum health and heart health: what to know this heart month

What is periodontal (gum) disease?

Periodontal disease is a chronic inflammatory condition caused by bacteria that build up around the gumline. It begins with gingivitis — red, swollen or bleeding gums — and can progress to periodontitis, where the supporting structures of the teeth begin to break down. Key signs include:

• Bleeding when brushing or flossing
• Persistent bad breath
• Receding gums
• Loose teeth
• Soreness or swelling

Left untreated, gum disease can affect more than just your mouth.

How gum disease affects the heart

Although the exact relationship is still being studied, research suggests several strong links between poor gum health and cardiovascular issues:

Inflammation in the body

Chronic gum disease increases inflammation in the bloodstream. This systemic inflammation is known to contribute to the development of atherosclerosis (narrowing of the arteries).

Bacteria entering the bloodstream

When gums are inflamed or infected, harmful oral bacteria can enter the bloodstream. These bacteria have been found in arterial plaque, where they may contribute to blockages.

Increased risk of cardiovascular events

Studies show that people with untreated gum disease have a higher risk of heart disease and may be more likely to experience heart attacks or strokes. While gum disease does not directly cause heart disease, it is considered a significant risk factor, and one that is preventable.

Protecting your gums to support heart health

Good oral hygiene is one of the simplest ways to support your heart. We recommend:

• Brushing twice daily with fluoride toothpaste
• Using interdental brushes or floss every day
• Regular dental check-ups
• Routine hygiene appointments to remove plaque and tartar
• Managing conditions like diabetes that can worsen gum health
• Quitting smoking if applicable

If you're noticing bleeding gums, sensitivity or persistent bad breath, it's important not to ignore these symptoms. Regular dental check-ups with our dentists in Teddington can help detect early signs before they progress.
