Poor dental health has long been associated with a range of health issues, from cavities and gum disease to heart disease. Now, new research suggests that it may also have a negative impact on brain health and increase the risk of stroke.
The study, which is yet to be published in a peer-reviewed journal, was presented at the American Stroke Association’s International Stroke Conference. It examined the link between oral health and brain health, specifically focusing on markers of poor oral health such as gum disease, missing teeth, and plaque buildup.
The researchers analysed data from the UK Biobank, which included information from around 40,000 adults with an average age of 57. They found that individuals with a genetic predisposition to cavities and missing teeth were more likely to have brain health issues, including damage to white matter in the brain.
Dr. Cyprien Rivier, a postdoctoral fellow in neurology at the Yale School of Medicine and one of the study authors, emphasised the importance of maintaining good oral hygiene. He stated that the study’s findings highlight the need to be “extra careful” with oral hygiene as it can have implications beyond just the mouth.
While the research is still in its early stages, Dr. Rivier and his colleagues hope that future studies will further confirm the link between oral health and brain health. They also believe that improving oral health could have significant benefits at a population level.
This study adds to the growing body of evidence that poor oral health can have negative effects throughout the body. Dr. Alan Reisinger, the associate medical director of healthcare company MDVIP, explains that when the body fights the bacteria that cause gum disease, it raises inflammation throughout the body. This systemic inflammation can increase the risk of various health problems, including heart attacks, strokes, dementia, pregnancy complications, and certain cancers.
Dr. Reisinger also highlights the importance of collaboration between the medical and dental communities in recognising the link between oral health and overall health. Organisations like the American Academy for Oral Systemic Health and the Integrative Dental Medicine Scholar Society are working towards fostering stronger collaboration and raising awareness of the impact of oral health on systemic diseases.
Preventing dental problems is crucial in maintaining overall health. Many dental issues develop slowly over time and can lead to more significant complications if left untreated. Regular visits to the dentist, along with daily at-home oral care, are essential for maintaining good oral health. Experts emphasise the importance of both aspects of oral care. At-home care helps keep the bacterial load down, while dental visits allow for professional cleaning and the removal of hard-to-reach bacteria.
This latest research suggests that poor oral health, including gum disease, missing teeth, and plaque buildup, may be linked to an increased risk of stroke and brain health issues. Maintaining good oral hygiene through regular dental visits and daily at-home care is crucial for overall health. Medical and dental communities are working together to raise awareness of the impact of oral health on systemic diseases. By taking steps to improve oral health, individuals may be able to prevent a range of health problems and enjoy better overall well-being.
