The Surprising Connection: Oral Health and Brain Health

In the wake of the COVID-19 pandemic, people's perspective on oral health has undergone a transformation. Previously overlooked, the mouth is now recognized as having its own microbiome and ecosystem, similar to the gut. It's becoming increasingly evident that an imbalanced oral microbiome not only contributes to oral diseases like decay and gum disease but also affects the development and severity of systemic conditions such as diabetes, heart disease, and even Alzheimer's. This article explores the intriguing link between oral health and brain health, shedding light on the importance of practices like flossing for improving overall well-being.

The Mouth as a Gateway to the Body:
The mouth is the gateway to the rest of the body, and its significance in the spread of infections became apparent during the COVID-19 pandemic. Saliva, which bathes the mouth, contains various bacteria, fungi, viruses, inflammatory markers, and enzymes. This realization has led to a shift in dentistry, with healthcare professionals recognizing the mouth as a vital component of achieving "full body health." By examining the oral cavity, we can gather valuable insights into an individual's overall health and detect various diseases beyond just COVID-19.

The Impact of Oral Health on General Well-being:
Dental professionals have discovered that addressing oral health issues not only restores function and eliminates infections but also has a positive ripple effect on general health. Collaborative efforts between dental professionals and other healthcare practitioners have proven particularly effective in treating conditions like chronic inflammatory diseases. For example, resolving periodontal disease, a common oral condition, can significantly reduce inflammatory markers throughout the body and alleviate systemic symptoms, improving conditions such as rheumatoid arthritis.

Unveiling the Connection to Alzheimer's:
One of the most surprising connections between oral health and overall well-being is the link between the mouth and Alzheimer's disease. While the exact cause of Alzheimer's remains unknown, recent research suggests that Porphyromonas gingivalis, a bacteria associated with chronic periodontal disease, may play a role. P. gingivalis releases neurotoxic enzymes called gingipains, which can travel from the mouth to the brain. Studies have found elevated levels of gingipains in the cerebrospinal fluid of Alzheimer's patients, along with increased production of amyloid plaques, a hallmark of the disease. Additionally, long-term gum disease has been associated with a 70% increased risk of developing Alzheimer's disease.

Tooth Loss and Cognitive Impairment:
The connection between oral health and cognitive function extends beyond bacteria. Research has revealed that adults with more tooth loss face a higher risk of dementia and cognitive impairment. The reasons behind this correlation are multifaceted, including difficulties in chewing and reduced nutrient intake due to tooth loss. Additionally, gum disease releases inflammatory markers that can contribute to inflammation in other parts of the body, including the brain.

Early Detection and Prevention:
Both periodontal disease and Alzheimer's often involve a preclinical stage of silent degeneration before clinical signs become evident. To address this, researchers are exploring the use of biomarkers found in saliva and blood to catch these conditions early. By identifying these "silent" diseases before irreversible damage occurs, personalized oral care regimes can be implemented. Biomarker testing, such as assessing levels of P. gingivalis, allows for targeted interventions to restore oral microbiome balance and improve overall health.

Taking Action for Better Oral and Brain Health:
Here are some practical tips to incorporate into your oral care routine:

1. Get your oral microbiome tested to identify any imbalances, including heightened levels of P. gingivalis.
2. Consult a dentist to develop a personalized treatment plan to reduce P. gingivalis levels through methods like Guided Biofilm Therapy and specific oral sprays.
3. Consider using Propolis, a natural substance known to combat periodontal disease and target P. gingivalis.
4. Make flossing a twice-daily habit to remove bacteria residing between the teeth that brushing alone can miss.
5. Switch to an electric toothbrush, as studies show it promotes healthier gums, reduces tooth decay, and helps maintain teeth for longer.

Conclusion:
The connection between oral health and brain health is an emerging field of research, shedding light on the profound impact that oral conditions can have on overall well-being. By recognising the mouth as a crucial aspect of full-body health, individuals can prioritise their oral care routines and work alongside dental professionals to detect and address potential issues early. Ultimately, by maintaining good oral hygiene practices, such as regular flossing, individuals can contribute to the improvement of both their oral and brain health, leading to a healthier and more fulfilling life.
