The study, published in the Journal of Epidemiology and Community Health, assessed how tooth retention influences the number of years lived with and without limitations in daily activities (Activities of Daily Living [ADLs], such as bathing, dressing and eating and physical function such as walking and climbing stairs). https://medicalxpress.com/news/2026-04-teeth-years-independent.html Wed, 15 Apr 2026 14:40:08 EDT news695476873 Recent advancements in digital and immersive technologies underscore the need for transformation in dental education; however, a new international study reveals that their adoption remains strikingly limited. Traditional simulations, such as phantom heads and benchtop exercises, still dominate about 80% of clinical training time, while haptic virtual reality (HVR) and mixed reality together account for only about 14% and are used in just a small minority of postgraduate programs. https://medicalxpress.com/news/2026-04-immersive-technologies-dental-limited-global.html Tue, 14 Apr 2026 15:40:01 EDT news695397541 Losing teeth might cause you to gain weight, a new study says. https://medicalxpress.com/news/2026-04-teeth-weight-gain.html Mon, 13 Apr 2026 22:00:01 EDT news695295963 Fluoride is a naturally occurring mineral that has been shown to strengthen teeth and reduce cavities. Many municipalities add fluoride to their drinking water—a process called community water fluoridation—as a public health measure to support dental health. In recent years, however, some have claimed that ingesting fluoride can harm children's IQ. Now researchers at the University of Minnesota have led a team that investigated the connection between fluoride in drinking water and children's IQ to see if these claims had merit. The work is published in the journal Proceedings of the National Academy of Sciences. https://medicalxpress.com/news/2026-04-fluoride-kids-iq-decades-analysis.html Mon, 13 Apr 2026 17:20:06 EDT news695316481 The human body is often described as a marvel of "perfect design": elegant, efficient and finely tuned for its purpose. Yet, when we look closer, a rather different picture emerges. https://medicalxpress.com/news/2026-04-human-body-isnt-masterpiece-patchwork.html Sat, 11 Apr 2026 15:30:01 EDT news694958813 Facial pain is one of the most common forms of chronic pain. Despite this, there has previously been no standardized burden measurements, such as impact on the individual and health care costs across countries and in relation to other diseases. A new international research collaboration, led by researchers at Umeå University, has now developed lay descriptions that make it possible to visualize the global burden of disease caused by facial pain. https://medicalxpress.com/news/2026-04-visualizing-global-burden-facial-pain.html Thu, 09 Apr 2026 19:00:01 EDT news694972021 Children who don't go to the dentist are less likely to participate in school-based cavity prevention programs, according to research published in JAMA Network Open.

It can lead to tooth loss and the destruction of supporting bone. This disease has also been linked to other health problems, including diabetes, respiratory infections, and heart disease, impacting quality of life and increasing health care costs. https://medicalxpress.com/news/2026-04-stiff-defense-physical-rigidity-healthy.html Wed, 01 Apr 2026 18:40:01 EDT news694258168 Oral Cancer Awareness Month is observed every April, and it highlights the urgent need for early detection. According to the American Cancer Society, oral and oropharyngeal cancers still claim about one life every hour in the U.S. This year, 59,600 Americans will be diagnosed with oral or oropharyngeal cancer. Many people are unaware of symptoms because early stages often cause no pain and may be inconspicuous. Most cases are diagnosed late, when treatment is harder and survival drops. https://medicalxpress.com/news/2026-04-hidden-dangers-oral-cancer.html Wed, 01 Apr 2026 16:30:05 EDT news694274708 A healthy mouth is key to protecting the well-being of people battling liver disease, a new study reports. Veterans with early-stage cirrhosis had fewer health problems and complications—including a lower risk of liver cancer—if they received routine dental cleanings, according to findings published in the Journal of Hepatology Reports. https://medicalxpress.com/news/2026-03-dental-cirrhosis-patients-liver-cancer.html Tue, 31 Mar 2026 20:20:02 EDT news694168370 Recently analyzed evidence points to a connection between oral health and kidney health, according to work led by University of Cincinnati College of Medicine researchers.

The research addresses the large overlap between gum disease and diabetes and is published in the Journal of Dentistry. https://medicalxpress.com/news/2026-03-prediabetes-diabetes-patients-dental.html Tue, 03 Mar 2026 19:50:01 EST news691754183 For years, treating gum disease has meant scraping away plaque, cutting out damaged tissue or turning to antibiotics that kill bacteria indiscriminately. While newer therapies can regenerate lost tissue, doctors still lack a precise way to stop the infection without harming the mouth's healthy microbiome. New research from the University of Florida College of Dentistry offers a breakthrough. https://medicalxpress.com/news/2026-03-gentler-aggressive-gum-disease-future.html Tue, 03 Mar 2026 15:50:01 EST news691775042 A tooth cavity and bleeding gums is a common scenario among Danish children—and one that researchers now connect to health problems long after the last baby tooth has left the mouth. Children who have multiple tooth cavities or suffer from severe gingivitis show a markedly higher incidence of stroke, heart attack, and coronary artery disease as adults. That's the conclusion of a new study by researchers at the University of Copenhagen. https://medicalxpress.com/news/2026-03-children-poor-oral-health-cardiovascular.html Mon, 02 Mar 2026 22:30:01 EST news691686195 Older Americans with oropharyngeal and oral cancers face high medical costs but are missing out on needed dental care, according to a new study by Associate Professor Onur Baser and colleagues. The study, published in Cancer Epidemiology, Biomarkers & Prevention, examined insurance claims from 2013–2024 for more than 100 million commercially insured adults and 7 million Medicare beneficiaries to track prevalence, health care spending and dental use among people with oropharyngeal and oral cancers. The researchers found that while these patients experienced serious treatment-related oral complications, they had fewer annual dental visits than similar adults without cancer in both Medicare and commercial plans. https://medicalxpress.com/news/2026-02-reveals-urgent-dental-coverage-reform.html Sun, 01 Mar 2026 16:30:03 EST news691335922 Nitrous oxide used for sedating patients during dental appointments has a significant environmental impact, with wide variation in use and wastage across the UK, according to a new study by UCL (University College London) researchers. https://medicalxpress.com/news/2026-02-dentists-unnecessary-nitrous-oxide.html Fri, 27 Feb 2026 15:00:04 EST news691426209 Everyone who's had regular dental care knows the heavy lead apron that's draped across your body before taking X-rays of your teeth. https://medicalxpress.com/news/2026-02-dental-guidelines-judicious-rays.html Fri, 20 Feb 2026 17:20:01 EST news690796664
