The Oral-Brain Connection: Understanding the Effect of Poor Oral Hygiene on Cognitive Decline

Scientific research has indicated a potential link between oral inflammation and a decline in cognitive abilities, emphasizing the significance of maintaining oral hygiene. Adults aged 65 years or older must take extra care of their oral health, as they are at a greater risk for developing periodontal disease, which can be associated with cognitive decline. The upcoming webinar from Professional Learning Services (PLS) titled “Poor Oral Hygiene and Cognitive Decline” aims to delve deeper into the relationship between oral hygiene and cognitive abilities, highlighting types of dementias associated with poor oral hygiene, p. gingivalis, the herpes virus, oral and systemic inflammation, brain atrophy, and comorbidities.

As the global population ages, dementia is expected to increase significantly, urging dental and health professionals to educate and motivationally interview clients to maintain good oral hygiene and continue care to prevent the development of comorbidities from systemic inflammation and shared risk factors. Oral infections, particularly gingivitis and periodontal diseases, may contribute to systemic inflammation or vascular issues such as bacteremia. Periodontal disease has been connected to Alzheimer’s disease and  Lewy body dementia, a dementia from abnormal protein deposits in the brain. The periodontal pathogen, p. gingivalis, plays a role in periodontal disease and can lead to the brain causing a chronic inflammatory response, increasing cognitive decline. Neuroinflammation, neuronal damage, and genetic predisposition from recurrent herpes viral activity can also contribute to severe cognitive decline. Therefore, there is a need to create prevention strategies against viral infections to reduce the risk of developing neurodegenerative conditions. Periodontal disease may exacerbate vascular dementia, which is from reduced blood flow to the brain. At the “Poor Oral Hygiene and Cognitive Decline” webinar, the exact mechanisms of oral infections and cognitive decline diseases, such as dementia, will be investigated.
