Simple brushing routine could reduce dementia risk, dental health experts say
NEWYou can now listen to Fox News articles!
Brushing your teeth could do more than brighten your smile. It may also help you live longer.
Growing research suggests that good oral hygiene is linked to a reduced risk of serious conditions, including Alzheimer’s disease and rheumatoid arthritis.
At the annual American Association for the Advancement of Science (AAAS) conference in Arizona last week, a group of researchers explored this evidence, calling the mouth a “gateway to overall health.”

During the event, “The Mouth as a Gateway to Overall Health,” panelists from medical schools across the U.S. discussed how the mouth was previously viewed as a separate entity from the rest of the body.
“However, researchers now know that the oral cavity and the body are deeply interconnected,” the presentation synopsis states on the AAAS website.

The panelists noted that past research suggests the oral cavity can influence the health of other organs, including the joints, brain and gut, according to Euro News.
Panelist Alpdogan Kantarci, a professor at the University of Minnesota’s School of Dentistry, reportedly said during the event, “We now think that maintaining your teeth in health may be associated with a reduced risk of more than 50 systemic conditions.”

“Research is now showing that in people with mild or moderate diseases, those who are brushing and taking care of their teeth or seeing a dentist and having advanced cleanings are showing much better cognitive responses,” he added.

The presenters discussed how periodontitis, a severe form of gum disease that worsens with age, affects the bone and tissues supporting the teeth.
The condition leads to “ongoing inflammation and progressive damage,” triggering immune responses and increasing the risk of rheumatoid arthritis and dementia.
Oral health and longevity
Research from Tufts University School of Dental Medicine in Boston, published in The Lancet, Health Longevity, in 2024, concluded that oral health should be considered an “integral component of the overall healthcare system and an important factor in accessing aging.”

“Oral health conditions could be potential risk factors for physical frailty or functional disability,” the authors stated. “The importance of oral health for overall well-being and longevity should be emphasized.”
Additional research published in the journal Neurology in 2023 found that people with good dental hygiene had better memory, while gum disease and tooth loss were linked with less gray matter in the brain and reduced decline in mental health.
“From a preventive health perspective, brushing three times a day helps control the bacterial biofilm that fuels gum disease and chronic inflammation,” a dentist said. (iStock)
The role of daily brushing
Dr. Michael J. Wei, a cosmetic and restorative dentist in New York City, confirmed that there are numerous benefits to brushing your teeth more frequently.
“From a preventive health perspective, brushing three times a day helps control the bacterial biofilm that fuels gum disease and chronic inflammation,” he told Fox News Digital. “Inflammation in the mouth does not remain isolated. It can influence cardiovascular health, metabolic function and immune balance.”
When plaque is disrupted throughout the day, the body’s inflammatory triggers are reduced, Wei said.

“Over time, lowering that burden may contribute to healthier aging and a reduced risk of systemic disease,” he said. “Small, disciplined daily habits often have the greatest long-term impact.”
Although maintaining proper oral health is not a “guaranteed safeguard” against dementia, Wei considers it “one meaningful way to reduce modifiable risk factors.”
“Protecting the health of your gums is part of supporting overall brain health,” a dentist told Fox News Digital. (iStock)
Consistently brushing, flossing, getting routine dental cleanings and addressing issues like grinding or jaw tension “all contribute to lowering inflammation and preventing long-term damage,” he added.
Technique matters
Brushing too much or too aggressively can lead to different complications, experts caution.
“Brushing too aggressively or using a hard-bristled toothbrush can lead to enamel wear, gum recession and tooth sensitivity,” Wei warned. “The balance comes down to frequency paired with proper technique, using a soft-bristled or electric toothbrush and gentle, controlled movements.”

Dr. Richard Lipari, a cosmetic and general dentist at Lipari & Mangiameli Dentistry in Chappaqua, New York, agreed that brushing teeth twice a day for two minutes with a soft-bristled toothbrush and gentle pressure is sufficient for proper hygiene and oral health.
“Oral care should be viewed as a core component of preventive medicine,” a dentist said. (iStock)
“Brushing a third time per day is fine as long as it’s done gently and correctly,” he told Fox News Digital. “Think of it as massaging the teeth and gums, not scrubbing them.”

Dr. Luis R. Dominicis Jr., associated vice president of dental services at AltaMed Health Services in California, recommends scheduling a routine dental checkup and asking about the proper way to brush and floss.
“Ask which toothbrush and toothpaste are best for you and whether there are signs of gum recession or enamel wear,” he advised in an interview with Fox News Digital. “Following your recommended treatment plan can help you maintain a healthy mouth and support your overall well-being.”

‘Call a Boomer’ payphones help cure loneliness, spark friendships across generations
NEWYou can now listen to Fox News articles!
Along a bustling sidewalk in Boston, a bright yellow payphone invites folks to “call a Boomer.”
Almost 3,000 miles away in Reno, Nevada, a nearly identical phone prompts residents of Sierra Manor – an apartment complex for seniors – to “Call a Zoomer.” The goal is simple: to get strangers to talk to each other.
The project, often referred to as simply “Call a Boomer,” is the latest initiative from Matter Neuroscience, a New York-based company dedicated to mapping the “biomarkers of happiness.”
NEARLY HALF OF SENIORS IMPROVE WITH AGE — AND RESEARCHERS THINK THEY KNOW WHY
By connecting “two of the loneliest demographics” (older adults and younger adults), the project aims to prove that on a molecular level, “humans need one another in order to be happy,” according to Calla Kessler, a social strategist at Matter Neuroscience.

“Younger adults and older adults tend to experience the highest levels of loneliness of any age group,” the company wrote on its website. “So the goal of this project is to inspire generational connection through meaningful conversations, despite differences in age, lifestyle or politics.”
GRANDPARENTS WHO BABYSIT THEIR GRANDCHILDREN STAY MENTALLY SHARPER, NEW STUDY REVEALS
The hope, according to Kessler, is that the calls will shift the brain’s focus from stress to bonding.
“Our neuroscience angle is cannabinoids over cortisol,” Kessler told Fox News Digital. “Cannabinoids are the feel-good neurotransmitter in our brain that creates that warm feeling with a friendship — and when you activate cannabinoids, you’re counteracting the negative effects of cortisol, which is our primary stress hormone.”
“Younger adults and older adults tend to experience the highest levels of loneliness of any age group,” the company noted. (Matter Neuroscience)
This isn’t Matter’s first round of payphones. Its initial experiment connected one of the most liberal cities in the U.S. (San Francisco) with one of the most conservative (Abilene, Texas).
“We basically just wanted people to find common ground and encourage people to think beyond labels,” Kessler said.

Family pleads for help as teen faces life-threatening bone marrow failure
NEWYou can now listen to Fox News articles!
A New York City father is desperately seeking a donor to save his teenage son’s life.
Max Uribe, now 15 and a high-school freshman, has just weeks until he will need to be hospitalized with a rare blood disorder that could lead to a deadly cancer.
“Max was just 6 when we first noticed there was something wrong with his blood counts,” his father, Juan Uribe, told Fox News Digital. “At the time, we thought it was due to a viral infection, but they never fully recovered back to their normal level.”

In December 2024, Max’s condition grew worse, and he was diagnosed with clonal cytopenia, a condition involving the blood and bone marrow.
“All three of his blood counts are low — red, white and platelets,” Uribe said.

In August 2025, another bone marrow biopsy revealed that Max is on a path to bone marrow failure, creating an urgent need for a stem cell transplant.
“The disease has continued to progress, as his blood counts continue to drop, and therefore, we have to take him to transplant in May of this year,” Uribe said.
MOM WITH NO SYMPTOMS HAD STAGE 4 COLORECTAL CANCER — AND A RARE SURGERY SAVED HER LIFE
If left untreated, Max’s condition could lead to MDS (myelodysplastic syndrome), a type of blood cancer, and from there possibly into acute myeloid leukemia (AML).
A bone marrow match must have a specific type of HLA (human leukocyte antigen), which are proteins found on the surface of most cells in the body, according to the National Marrow Donor Program (NMDP).

The closer the donor’s HLA markers are to the patient’s, the more likely the body will accept the new cells without a high risk of complications.
People from the same ethnic background are more likely to share similar HLA types, meaning a patient is most likely to find a compatible donor among individuals with similar ancestry, per the NMDP.

Non-Hispanic White patients have a 79% chance of a perfect match. That drops to 49% for Hispanic/Latino patients, 29% for Black patients and even lower for mixed ancestries, the NMDP reports.
Because Max is a “very rare combination” of half-Colombian from his father and a mix of Italian, British and German from his mother, his path to a perfect match is proving much more difficult, Uribe noted.
“For a kid like Max, with complex, mixed heritage, the math is devastating.”

Max, who participates in competitive tennis and varsity wrestling, just had additional blood work done on Friday, which revealed that his counts continue to plummet.
“We’re at the point where this is beginning to manifest a bit more, which is why the urgency is so critical,” Uribe said.

If a donor is not secured by Max’s hospitalization in May, the medical team will have to proceed with a partial match, which is not ideal for a number of reasons.

“The survival rate is meaningfully lower with a partial match, and there’s more risk of graft versus host disease (GVHD), which could lead to complications in the process,” Uribe said. With GVHD, the donor cells begin to attack the body.

To help prevent this with a partial match, Max would likely need chemotherapy and immunosuppressants for a longer period of time, which could weaken his immune system.
