🦷 Research shows exercise and omega-3s literally protect your teeth.

A new study has found that combining regular physical exercise with omega-3 fatty acid supplementation can significantly enhance immune function and reduce inflammation linked to chronic apical periodontitis—a dental condition that affects the root of a tooth and can lead to bone loss if untreated.

Conducted in rats, the research showed that swimming alone helped regulate immune response, but when paired with omega-3 supplements, it further minimized bacterial spread, bone degradation, and inflammation.

Published in Scientific Reports, this is the first study to show how this dual approach could strengthen oral health and prevent progression of a commonly overlooked condition.

Apical periodontitis is typically caused by untreated cavities that allow bacteria to reach the tip of the tooth root. Left unchecked, it can silently damage bone and teeth, and may worsen during immune suppression. Interestingly, this inflammation has also been linked to systemic health problems like diabetes and kidney disease. While more research is needed in humans, this animal study adds to growing evidence that lifestyle factors like exercise and diet—particularly omega-3 intake—play a powerful role not only in general immunity, but also in maintaining oral health.

In 1816, one of Sir Isaac Newton’s teeth was sold at auction for the remarkable sum of $3,633 — an enormous amount for the time. The buyer, believed to be an aristocratic admirer of Newton’s genius, had the tooth set into a ring, transforming the relic into an unusual piece of scientific and historical jewelry. Often referred to as the “Tooth of Genius,” the ring is said to feature the tooth framed in gold, a physical connection to one of history’s greatest minds.

Over two centuries later, this rare artifact remains a fascinating symbol of how deeply society revered Newton’s intellect and legacy. Collectors of historical memorabilia have continued to show interest, and the ring is now estimated to be worth around $62,000, though some appraisals place it closer to $30,000 depending on provenance and condition.

In 1816, one of Sir Isaac Newton's teeth was sold for $3,633, a substantial amount that reflects its historical and personal significance. Today, this rare and valuable artifact, now transformed into an elegant ring, is worth around $62,000. The transformation of Newton's tooth into a ring underscores the unique appeal of personal items associated with iconic figures like Newton, whose scientific contributions continue to inspire generations. As a highly sought-after collector's item, this piece exemplifies the intersection of history, science, and luxury, making it a prized asset for investors and collectors alike. Newton's legacy elevates the value of such artifacts, driving up their worth in the high-end collectibles market.

Teeth are the only part of the human body that cannot heal on their own particularly the enamel. Unlike bone or skin, enamel has no living cells, no blood supply, and no ability to regenerate. Once it’s damaged by decay, trauma, or erosion, the loss is permanent.

While minor remineralization can occur in early stages through fluoride and saliva, true biological repair never happens. Dentin and pulp may respond to irritation, but their healing capacity is extremely limited.

That’s why preventive care brushing, flossing, fluoride use, and regular dental visits remains the strongest defense. Once enamel is gone, only a dentist can restore what nature cannot.

When a tooth goes missing and isn’t replaced, the surrounding teeth slowly shift toward the gap, disrupting your bite alignment. Over time, this can lead to difficulty chewing, jaw pain, and uneven wear on remaining teeth. The jawbone beneath the missing tooth can also begin to shrink a natural process called bone resorption causing your facial structure to sag and age prematurely.

Beyond appearance, a missing tooth can trap food, increase plaque buildup, and raise the risk of gum disease. Whether through a dental implant, bridge, or denture, replacing it promptly protects both your smile and overall oral health.

Brushing your teeth twice a day morning and night is essential for good oral health. However, brushing right after a meal can actually damage your teeth, especially if you’ve eaten acidic foods like citrus, tomatoes, or vinegar-based dishes. After eating, the enamel temporarily softens, making it more vulnerable to erosion.

Dentists recommend waiting at least 30 minutes before brushing. This pause allows saliva to neutralize acids and start the natural remineralization process, protecting your enamel from wear. Brushing too soon can increase sensitivity and gradually weaken your teeth over time.

By simply timing your brushing correctly, you can maintain strong, healthy teeth and avoid unnecessary enamel damage keeping your smile bright and pain-free.

Brushing with the non-dominant hand may look awkward—but it’s one of the simplest ways to engage your brain while caring for your oral health. Studies in neuroplasticity show that performing routine actions differently forces the brain to “wake up,” strengthening communication between both hemispheres. This cross-activation boosts coordination, focus, and adaptability—just like exercising a new muscle.

When the brain encounters an unfamiliar task, it forms new neural pathways to handle it. Over time, these small daily challenges improve cognitive resilience and keep gray matter active. The process is similar to mental “resistance training,” enhancing memory and attention while reducing the long-term risk of cognitive decline. Even subtle acts—switching brushing hands or changing brushing sequence—train the brain to stay alert and flexible.

A new study shows that skipping tooth brushing at night can put more than your smile at risk it may also harm your heart. Researchers found that poor nighttime oral hygiene is linked to a higher risk of cardiovascular disease due to bacteria that thrive in the mouth while we sleep.

When teeth aren’t brushed before bed, bacteria multiply and trigger gum inflammation. This allows toxins to enter the bloodstream, contributing to artery plaque, higher blood pressure, and greater chances of heart problems. Nighttime is especially critical since saliva flow drops, making it easier for bacteria to grow unchecked.

Experts recommend brushing for at least two minutes with fluoride toothpaste, along with flossing and mouthwash. This simple habit doesn’t just protect against cavities it also supports long-term heart health, proving that caring for your smile can also protect your life.

🦠 Oral Microbes and Pancreatic Cancer: A Hidden Connection

A groundbreaking study from NYU Langone Health has found that certain microbes in the mouth can dramatically increase the risk of pancreatic cancer—the third deadliest cancer worldwide.

Researchers analyzed oral wash samples and health records from over 300,000 adults aged 50–70 and discovered that the presence of specific bacteria and fungi was strongly tied to pancreatic cancer development.

🔬 Key findings:

• The bacteria Porphyromonas gingivalis, Eubacterium nodatum, Parvimonas micra, and the fungus Candida tropicalis were linked to a 250% higher risk.

• In total, 13 oral microbes were tied to higher risk while 8 were linked to lower risk, suggesting that the balance of oral microbiota plays a protective—or harmful—role.

• The microbes may travel from saliva into the digestive tract, potentially reaching the pancreas and influencing cancer risk.

Pancreatic cancer has a five-year survival rate of only 13%, mainly because it is usually diagnosed late. This study underscores the importance of oral health, suggesting that daily brushing and flossing could one day be considered part of cancer prevention.

Next, researchers plan to investigate whether oral viruses also contribute to pancreatic cancer.
