Brushing Your Teeth and Longevity

Brushing your teeth might do more than just enhance your smile; it could actually contribute to a longer life.

Emerging studies indicate that maintaining good oral hygiene is associated with a lower risk of serious health conditions, including Alzheimer’s disease and rheumatoid arthritis.

At the recent American Association for the Advancement of Science (AAAS) conference in Arizona, researchers examined this correlation, describing the mouth as a “gateway to overall health.”

During a session named “The Mouth as a Gateway to Overall Health,” medical professionals from various U.S. universities discussed how the mouth has often been perceived as separate from overall bodily health.

Interestingly, the synopsis of their presentation noted that researchers now recognize a close connection between the oral cavity and the body as a whole.

The panelists highlighted previous findings suggesting that oral health can impact other organ systems, including the joints, brain, and gut, as reported by Euro News.

Professor Alpdogan Kantarci from the University of Minnesota’s School of Dentistry stated, “We now believe that keeping your teeth healthy may correlate with a reduced risk of over 50 systemic conditions.”

He went on to point out that research shows individuals with mild or moderate diseases who brush regularly and visit the dentist for cleanings exhibit noticeably improved cognitive responses.

The discussion also touched on periodontitis, a serious gum disease that worsens with age and affects the supporting structures of teeth.

This condition can cause “chronic inflammation and progressive damage,” potentially triggering immune responses that elevate risk for rheumatoid arthritis and dementia.

Research from Tufts University School of Dental Medicine, published in The Lancet, emphasized that oral health should be viewed as an “integral component” of overall health care and is vital for aging.

The authors noted, “Oral health conditions may be risk factors for physical frailty or disability. The significance of oral health for overall well-being and longevity cannot be overstated.”

Another study in the journal Neurology in 2023 found that individuals with good dental practices had better memory retention, while gum disease and tooth loss were linked to lower gray matter levels in the brain and worsened mental health.

From a preventive health viewpoint, Dr. Michael J. Wei, a dentist in New York City, highlighted that brushing three times daily can help manage the bacteria that contribute to gum disease and chronic inflammation. He explained that inflammation doesn’t stay localized; it can affect cardiovascular health, metabolic function, and immune systems.

“Disrupting plaque throughout the day lessens inflammatory triggers,” Wei noted, suggesting that these small habits can significantly impact long-term health.

While maintaining oral hygiene isn’t a foolproof way to prevent dementia, Wei thinks it serves as a meaningful method to lower modifiable risk factors.

Keeping your gums healthy is closely related to brain health, according to dental experts. Regular brushing, flossing, and routine dental visits are instrumental in minimizing inflammation and preventing damage over time.

However, they cautioned against the dangers of over-brushing, which can lead to enamel erosion and other complications. Wei remarked, “It’s about frequency combined with the right technique—using a soft-bristled toothbrush and adopting gentle motions.”

Dr. Richard Lipari, another dentist, concurred that brushing for two minutes twice daily with a soft brush is typically sufficient for good oral hygiene and overall oral health.

He added that brushing a third time daily is acceptable as long as it is done gently, treating it more like a massage than a scrub.

Dr. Luis R. Dominicis Jr. from AltaMed Health Services recommended routine dental checkups and consultations about the best brushing and flossing techniques tailored to individual needs. He stressed that following dental advice can help ensure a healthy mouth and enhance overall wellness.
