A healthy smile, for a healthy heart...
The health of the mouth and the heart can have an effect on each other; when one isn’t properly cared for, the other can suffer too.
Problems with your dental health can sometimes serve as an early warning sign for other diseases or conditions and increase their likelihood. More research is needed in this area, but it has previously been found that if you have a heart condition, you are more likely to have gum disease and vice versa.
Gum disease also known as periodontal disease, begins with gingivitis, symptoms of which are swollen, red and sore gums that often bleed when you brush your teeth. If gingivitis is left untreated, it can progress to periodontitis. Periodontitis affects the strength of the gum and bone around the teeth, causing them to loosen and in the worst-case scenario, the teeth can fall out.
Gum disease can also contribute to general inflammation, where your body is constantly on high alert with your immune system always defending the body. Inflammation is a known risk factor for cardiovascular disease (CVD), including heart attacks and strokes.
Bacteria in the mouth is called plaque. It is the soft, creamy-coloured sticky substance that forms on our teeth. If is plaque left on the teeth and gums it can lead to gum disease. If you suffer with gum disease, this bacteria from the affected gums can enter the bloodstream. This can be a severe problem for the heart, as it increases the risk of hardened arteries, which can increase the risk of stroke and heart attacks.
These bacteria from the mouth can also spread to the heart valves via the bloodstream, causing endocarditis. Endocarditis is the inflammation of the inner layer of the heart. This is particularly risky for individuals with pre-existing heart valve conditions.
How can I do preventative care at home?
One of the best things you can do at home to help your overall health is to take preventative care seriously and look after your mouth health. This should include:
• Brushing for two minutes, last thing at night and at least one other time during the day using fluoride toothpaste.
• Cleaning between your teeth once a day, using interdental brushes, tape or floss.
• Visiting your dentist and/or hygienist regularly, as often as they recommend.
• Cutting down on sugar and how often you have it.
• Use mouthwash alongside your dental routine.
These habits form the foundation of good oral hygiene and help to lower the risks of gum disease and heart problems. Brushing and interdentally cleaning removes harmful plaque, the buildup of bacteria that can trigger gum inflammation and potentially enter the bloodstream, affecting your heart. Regular dental visits can catch early signs of gum disease or tooth decay, addressing problems before they escalate.
Beyond hygiene, a balanced diet rich in fresh fruits, vegetables, and calcium-rich foods like milk and yoghurt supports both strong teeth and a healthy heart. Limiting sugary snacks and drinks not only prevents tooth decay but also lowers your risk of conditions like diabetes and obesity, which are linked to cardiovascular health.
Remember, small daily actions can have significant long-term benefits. Treat your oral hygiene routine as an investment in your overall wellbeing. By protecting your mouth, you’re also showing love to your heart.
The link between your heart and your mouth is a powerful reminder of how interconnected our bodies truly are. By maintaining a good oral health routine, such as brushing twice daily, cleaning between your teeth, and visiting your dentist regularly, you’re not just protecting your smile – you’re also supporting your heart ❤️
