How taking care of your teeth could protect your heart and brain health
In recent years, there has been a growing body of research suggesting a potential link between oral bacteria and Alzheimer’s disease. This connection has raised concerns for individuals with poor dental health, highlighting the importance of maintaining good oral hygiene for overall health benefits.
With close to 700 different species of bacteria residing in the human mouth, experts emphasize the significance of proper oral care not only for dental health but also for the well-being of the heart and brain. Studies have indicated that good oral health practices could potentially play a role in preventing Alzheimer’s disease. For example, a study published in the Journal of Alzheimer’s Disease found that individuals who consistently flossed had a reduced risk of developing Alzheimer’s compared to those who did not prioritize oral hygiene.
Despite the promising findings, researchers caution that there is still limited evidence to definitively prove that flossing directly prevents Alzheimer’s disease. Dr. Celine Gounder, a medical contributor for CBS News, explains that poor gum and dental health essentially amount to a bacterial infection, which can lead to chronic inflammation and increase the risk of various diseases, including heart and brain conditions.
According to the Centers for Disease Control and Prevention, approximately 40% of adults aged 30 and above in the United States have some form of periodontal disease. In addition to causing inflammation, the bacteria associated with gum disease can produce enzymes that are harmful to nerves and weaken the blood-brain barrier, potentially allowing toxins and bacteria to enter the brain. These oral bacteria have also been linked to an increase in amyloid, a protein plaque associated with Alzheimer’s disease.
The pathway from the mouth to the brain occurs when bacteria from oral issues enter the bloodstream, emphasizing the importance of good oral health practices in overall health maintenance. While tools like water picks and mouthwash can offer some benefits, they are not sufficient replacements for flossing. Dr. Gounder stresses that flossing is crucial for removing plaque and bacteria from hard-to-reach areas between teeth.
The National Institutes of Health identify several signs of gum disease, including red, swollen, or bleeding gums, pain while chewing, persistent bad breath, and loose or sensitive teeth. To prevent gum disease and its potential consequences, the NIH recommends brushing teeth with fluoride toothpaste, flossing regularly, visiting the dentist biannually, and avoiding smoking.
The general recommendation is to floss at least once daily, preferably before bedtime. Individuals with specific health conditions such as gingivitis, receding gums, diabetes, or heart disease may benefit from flossing at least twice daily. By prioritizing good oral hygiene practices, individuals can potentially reduce their risk of developing not only dental issues but also systemic conditions like Alzheimer’s disease.
