Brushing Your Teeth: More Than Just a Bright Smile
It turns out that brushing your teeth might do more than just enhance your smile — it could potentially increase your lifespan, too.
Research is increasingly indicating that proper oral hygiene is associated with a lower risk of serious illnesses, such as Alzheimer’s disease and rheumatoid arthritis.
At the recent American Association for the Advancement of Science (AAAS) conference in Arizona, researchers discussed this growing body of evidence, suggesting that the mouth acts as a “gateway to overall health.”
During the session titled “The Mouth as a Gateway to Overall Health,” experts from various U.S. medical schools highlighted how the relationship between the oral cavity and the rest of the body is far more interconnected than previously thought, as indicated in the presentation summary on the AAAS website.
The panel pointed out that older studies implied the mouth was separate from the body’s other systems. However, new findings reveal it can actually influence the health of major organs like the brain, joints, and gut, according to Euro News.
Alpdogan Kantarci, a professor at the University of Minnesota’s School of Dentistry, remarked at the event that maintaining healthy teeth is now believed to correlate with a reduced risk for over 50 systemic conditions. This could be quite significant.
He also mentioned that individuals suffering from mild or moderate diseases who engage in regular brushing and dental care exhibit enhanced cognitive responses compared to those who don’t.
The discussion also touched on periodontitis, a severe form of gum disease exacerbated by age, which affects the supporting tissues of the teeth. This condition often leads to prolonged inflammation, immune responses, and an elevated risk for issues like rheumatoid arthritis and dementia.
A study by Tufts University School of Dental Medicine, published in The Lancet, Health Longevity, in 2024, highlighted the importance of oral health as a critical aspect of overall health care, especially as we age.
The authors noted that oral health conditions could be significant risk factors for physical frailty. They stressed the importance of oral health for overall well-being and longevity.
Further research published in the journal Neurology found that individuals with good dental hygiene exhibited better memory. Conversely, gum disease and tooth loss were linked to decreased gray matter in the brain, which can contribute to a decline in mental health.
From a preventive health standpoint, Dr. Michael J. Wei, a cosmetic dentist in New York City, noted that brushing three times a day can aid in controlling the bacterial film that leads to gum disease and chronic inflammation. He pointed out that inflammation in the mouth can also affect cardiovascular health and immune function.
Disrupting plaque regularly helps to lower the body’s inflammatory triggers, which might contribute to healthier aging and a reduced risk of systemic disease.
Maintaining proper oral hygiene surely isn’t a “foolproof safeguard” against dementia, but Wei sees it as a valuable way to minimize risk factors we can control.
Consistent brushing, flossing, and addressing teeth grinding or jaw tension can all play a role in lowering inflammation and preventing long-term damage. However, experts do caution against brushing too vigorously. Overdoing it can lead to problems like enamel wear and gum recession, which isn’t ideal for anyone.
Dr. Richard Lipari, another dentist based in New York, agreed that brushing twice a day for two minutes with gentle pressure is usually sufficient for maintaining oral health. He added that brushing a third time is acceptable as long as it’s done carefully — thinking of it like a gentle massage rather than a scrub.
Lastly, Dr. Luis R. Dominicis Jr., who oversees dental services at AltaMed Health Services in California, urged individuals to schedule regular check-ups and get personalized advice on effective brushing and flossing techniques to ensure a healthy mouth and support overall health.
