TV doctor Dr Amir Khan has issued a stark health warning to his followers, highlighting a daily habit that could significantly protect against serious diseases like heart disease and dementia. The expert emphasizes that poor oral health is not just about teeth and gums but has far-reaching implications for overall well-being.
The Link Between Gum Disease and Chronic Illnesses
In a detailed video shared on his Instagram page, Dr Amir Khan, known for his appearances on ITV, explained how gum disease can trigger widespread health issues. He stated that gum disease is a chronic inflammatory condition caused by bacteria accumulating under the gum line. These bacteria activate the immune system, releasing inflammatory cytokines that do not remain confined to the mouth.
"These inflammatory substances spill into the bloodstream, creating a state of low-grade, widespread inflammation throughout the body," Dr Amir said. "This systemic inflammation can drive many chronic diseases, including heart disease and Alzheimer's."
Impact on Heart and Brain Health
Dr Amir elaborated that the bacteria associated with gum disease can enter the bloodstream and attach to the inner lining of blood vessels. This contributes to arterial narrowing by promoting plaque formation and instability. "Inflammation also makes plaques more likely to rupture, increasing the risk of heart attacks and strokes," he added.
Regarding brain health, emerging research has found oral bacteria in the brains of patients with Alzheimer's disease. "These bacteria may travel via the bloodstream or nerves, triggering chronic inflammation in the brain and contributing to neurodegeneration over time," Dr Amir revealed, though he noted that more research is needed in this area.
Additional Health Risks Linked to Poor Oral Hygiene
Beyond heart and brain diseases, Dr Amir highlighted other critical health connections:
- Diabetes: There is a two-way relationship between gum disease and diabetes. High blood sugar weakens the immune response, making gum infections more likely and severe. Conversely, gum disease increases inflammation and worsens insulin resistance, complicating blood glucose control. Dentists often spot early warning signs like persistent gum infections or slow healing.
- Pregnancy Complications: Poor oral health has been linked to premature birth and low birth weight. Inflammatory chemicals and bacteria from gum disease can reach the placenta, potentially triggering early labour or affecting foetal growth.
How to Protect Your Oral Health
Dr Amir advised maintaining rigorous oral hygiene to safeguard overall health. "Make sure you're brushing, flossing, and going for regular dental checks because it protects your heart, your brain, your metabolism, and even future pregnancies, not just your teeth," he urged.
To prevent gum disease, the NHS recommends:
- Brush your teeth with fluoride toothpaste at least twice a day – spit after brushing, do not rinse.
- Clean between your teeth daily using floss or interdental brushes.
- Change your toothbrush every one to three months.
- Regularly visit a dentist and dental hygienist, especially if pregnant or have type 2 diabetes.
- Avoid using mouthwash immediately after brushing your teeth.
- Refrain from smoking.
By adhering to these practices, individuals can reduce inflammation and lower their risk of developing severe health conditions linked to oral hygiene neglect.
