While common and unpleasant, may have far-reaching consequences beyond oral health. Growing evidence suggests it could be connected to an unexpected range of seemingly unrelated health problems. Proper oral hygiene and regular dental care are now being recognized as crucial for more than just a bright smile.
Plaque, a sticky substance containing bacteria, can build up on teeth and, if not brushed away, irritate the gums, leading to swelling, soreness, or infection known as gingivitis. While maintaining good oral health can prevent or treat gum disease, if left untreated, it can progress to periodontitis, which weakens the supporting structures of the teeth.
Although spatially the gums are near the brain, one wouldn’t normally associate dental complaints with neurological conditions.
However, some studies have found a link between periodontal disease and tooth loss and cognitive function. One study looking at cognitive performance followed 597 men for up to 32 years. The authors conclude:
Risk of cognitive decline in older men increases as more teeth are lost. Periodontal disease and caries, major reasons for tooth loss, are also related to cognitive decline.
Researchers have made compelling connections between periodontal disease and Alzheimer's disease, uncovering potential implications for neurological health. Studies have found an association between periodontal disease and increased buildup of beta-amyloid in the brain, which is a hallmark of Alzheimer's.
Further investigations have revealed that a specific type of bacteria, Porphyromonas gingivalis, commonly found in cases of periodontitis, can also be present in the brains of individuals with Alzheimer's. Building on this discovery, a more recent study demonstrated that infection with P. gingivalis can actually stimulate the production of beta-amyloid in the brain.
These intriguing findings raise important questions about the potential role of periodontal health in the development and progression of Alzheimer's disease. The ongoing research sheds light on the intricate relationship between oral health and brain health, emphasizing the significance of maintaining a healthy mouth for overall well-being. As our understanding of these connections grows, so does the importance of comprehensive dental care as part of a holistic approach to health.
