As we age, our oral health becomes increasingly important, not just for maintaining a healthy smile, but also for our overall well-being, including cognitive function. Interestingly, oral microbial dysbiosis, a chronic condition affecting more than 50% of older adults, has been linked to a higher brain amyloid-beta load and the development of Alzheimer's disease.
The link between oral health and Alzheimer's disease can lead to early diagnosis and interventions. Assessing specific microbiome diversity in the oral cavity may serve as a valuable risk biomarker for the early stages of Alzheimer's or as a predictor of disease progression.

What Is Alzheimer’s Disease?
Alzheimer's disease (AD) is a neurodegenerative disorder characterized by progressive cognitive decline, including memory loss, impaired thinking and problem-solving skills, and changes in behavior and personality.
Your risk of developing Alzheimer’s is influenced by a complex interplay of environmental, epigenetic, and genetic factors. The accumulation of amyloid-beta (Aβ) plaques in the brain is a central pathological feature of AD. These plaques are believed to result from the host's immune response to pathogens in both the central nervous system and peripheral systems.
Understanding the risk factors and underlying mechanisms of AD is crucial for developing effective prevention and treatment strategies. Research suggests that environmental factors, such as oral microbiome dysbiosis, may contribute to the development of AD.
Recent studies have highlighted the potential role of the gut microbiota in AD progression. Modulating the gut microbiota through interventions such as diet and probiotics has shown promise as a therapeutic approach for AD.
What Is The Oral Microbiome?
The oral microbiome is a community of microorganisms, including bacteria, fungi, viruses, and protozoa, that reside in our mouth. These microorganisms form biofilms, which are complex structures that play a crucial role in maintaining oral homeostasis and protecting our mouth from diseases.
When our oral microbiome is in balance, beneficial microorganisms keep harmful pathogens in check, preventing the development of dental caries, gum disease, and bad breath. It's important to note that several factors can influence the balance of our oral microbiome, including genetics, diet, oral hygiene practices, and environmental exposures.
A healthy oral microbiome is also believed to support our immune system and contribute to our overall systemic health. However, when the balance of our oral microbiome is disrupted, a condition known as dysbiosis occurs.
Dysbiosis in the oral microbiome can have significant implications for our oral health and contribute to the development of various diseases. Pathogenic microorganisms can flourish, leading to oral health issues such as dental infections, periodontitis, and oral candidiasis.
While it may be challenging to completely alter the oral microbiome, certain lifestyle changes can contribute to microbial balance.
Alzheimer's Disease And The Oral Microbiome
Several studies have investigated the potential link between oral microbial dysbiosis and AD. These studies have found that oral microbial dysbiosis is associated with a higher brain Aβ load and an increased risk of developing AD.
Furthermore, an oral-derived and predominant microbiome has been identified in the brains of patients with AD and other neurodegenerative diseases. This suggests that oral bacteria may play a role in the pathogenesis of AD.
One specific bacterium that has been implicated in AD is Porphyromonas gingivalis (P. gingivalis). P. gingivalis is an oral pathogen that contributes to the development of chronic periodontitis, a common oral inflammatory disease. Studies have shown that P. gingivalis can promote the formation of Aβ plaques and contribute to AD pathology.
These findings suggest that oral microbial dysbiosis, particularly the presence of specific bacteria like P. gingivalis, may play a role in the development and progression of AD. While the exact mechanisms through which oral bacteria contribute to AD pathology are not yet fully understood, further research in this area may provide valuable insights into potential preventive and therapeutic strategies for AD.
Balancing The Oral Microbiome Through Functional Dentistry
Functional dentistry offers a personalized and integrated approach to dental care that goes beyond treating symptoms. It recognizes the bidirectional relationship between the oral and gut microbiomes and understands the impact of various factors on oral health, including genetics, diet, oral hygiene practices, and environmental exposures.
One way functional dentistry can assist with balancing the oral microbiome is through functional testing. Functional dentists can utilize oral microbe testing to gain a better understanding of an individual's unique microbiome composition. This testing can provide insights into the overall health status of the oral microbiome and help identify any imbalances or dysbiosis.
Gut microbiome testing may also be relevant as the oral and gut microbiomes have a bidirectional relationship, influencing each other. By assessing the health of the gut microbiome, functional dentists can gain a better understanding of overall oral health status.
Functional dentists also collaborate with medical providers to ensure a coordinated approach to oral and systemic health. This collaboration allows for a more complete understanding of how various factors, such as nutrition, stress, and sleep, influence oral health.
Lifestyle Changes For Improved Oral Health
Functional dentistry and lifestyle changes can play a crucial role in improving oral health and potentially reducing the risk of cognitive decline associated with Alzheimer's disease. By educating patients about the role of nutrition in oral health and providing personalized dietary recommendations, functional dentistry can help individuals make informed choices that support their oral health.
In addition to testing and education, functional dentistry also offers practical interventions to balance the oral microbiome. Practices such as oil pulling, which involves swishing oil in the mouth, can help remove harmful bacteria and promote a healthier oral microbiome.
Avoiding excessive sugar consumption and processed foods, as well as including prebiotic-rich foods in the diet, can also support the restoration of a healthy oral microbiome.
By involving patients in the decision-making process and empowering them to participate in their oral health journey, functional dentistry enhances patient education and improves treatment adherence and outcomes.
