This was demonstrated in an animal model study conducted by researchers at the Ribeirão Preto School of Dentistry at the University of São Paulo (FORP-USP) in Brazil. The results were published in May in the scientific journal Calcified Tissue International. https://medicalxpress.com/news/2026-08-rat-early-secondhand-exposure-tooth.html Sat, 01 Aug 2026 07:00:03 EDT news704769247 A major study has ruled out inflammation as the cause of a developmental condition affecting children's teeth while also revealing how common the condition is. https://medicalxpress.com/news/2026-07-root-common-dental-defect-children.html Thu, 30 Jul 2026 10:20:03 EDT news704622291 Every year, untreated tooth decay sends thousands of young U.S. children to emergency departments for dental problems doctors can't treat. Many eventually undergo surgery under general anesthesia, while others endure pain and infection. https://medicalxpress.com/news/2026-07-silver-diamine-fluoride-treatment-halt.html Mon, 27 Jul 2026 15:20:05 EDT news704381521 A team of researchers from VCU Massey Comprehensive Cancer Center, the VCU School of Dentistry and the University of Pennsylvania recently published a study in Nature Communications examining why some oral inflammatory diseases progress much more rapidly than others. https://medicalxpress.com/news/2026-07-oral-inflammatory-diseases-human.html Sat, 11 Jul 2026 13:00:01 EDT news702822164 Temporomandibular disorders (TMDs) are a group of more than 30 conditions that cause pain and dysfunction in the jaw.

Their study, published in Cell Reports, describes a molecular mechanism—a defect in calcium signaling—behind low saliva production, along with other factors that may contribute to gum disease. https://medicalxpress.com/news/2026-06-faulty-calcium-dry-mouth-syndrome.html Wed, 01 Jul 2026 11:00:21 EDT news701970721 Periodontal (gum) disease is one of the most prevalent diseases worldwide, caused by the bacterium Porphyromonas gingivalis (P. gingivalis). In Japan alone, approximately 80% of adults 30 and older are affected or considered at risk. https://medicalxpress.com/news/2026-06-cryo-em-mechanisms-dental-plaque.html Tue, 30 Jun 2026 13:20:08 EDT news702038341 Researchers at the University of Basel have developed a miniature dental robot that could one day automatically prepare teeth for crowns. The technology could help reduce the number of appointments needed for dental treatment. https://medicalxpress.com/news/2026-06-mini-robot-dental-treatment-teeth.html Tue, 23 Jun 2026 10:00:07 EDT news701426761 Continuous consumption of foods containing heat-inactivated Lactiplantibacillus pentosus can help reduce gum bleeding, report researchers from Institute of Science Tokyo. These postbiotic foods can improve inflammatory conditions and enhance gum health in adults with mild gingivitis. The study suggested that these postbiotic foods offer a simple and practical way to support oral health in daily life without altering oral care habits. The findings also aid in the prevention of early-stage periodontal disease. https://medicalxpress.com/news/2026-06-postbiotic-gummies-gum-weeks-trial.html Wed, 17 Jun 2026 20:20:01 EDT news700914617 Dental implants have given tens of millions of people something dentures never could: a full set of fixed and fully functioning teeth. Unfortunately, 10% to 20% of implant patients eventually experience an aggressive jawbone infection called peri-implantitis. Antibiotics usually fail to stop the infection for reasons that researchers have not understood until now. https://medicalxpress.com/news/2026-05-titanium-particles-antibiotics-dental-implant.html Thu, 28 May 2026 16:00:06 EDT news699199321 A new study led by Prof. Michael Klutstein at the Hebrew University of Jerusalem and Prof. Asaf Wilensky at the Hebrew University-Hadassah Medical Center and spearheaded by the students Dr. Paz Kles and Stephen Ameho has uncovered a striking biological link between chronic oral inflammation and female fertility, suggesting that conditions in the mouth may have far-reaching effects on reproductive health. https://medicalxpress.com/news/2026-05-oral-inflammation-ovaries-fertility-decline.html Thu, 28 May 2026 10:20:01 EDT news699179549 Cancer diagnosis can be challenging, and delayed diagnosis can allow cancer to progress, complicating treatment. Oral squamous cell carcinoma (OSCC), the most common type of oral cancer, can sometimes mimic benign conditions, such as gum disease or oral infections, making diagnosis difficult. Therefore, identifying new diagnostic methods for OSCC is crucial. https://medicalxpress.com/news/2026-05-rare-burrowing-oral-cancer-distinct.html Tue, 26 May 2026 07:40:20 EDT news698999227 With age, teeth get increasingly brittle and susceptible to damage from tooth decay, which can eventually lead to tooth loss. Teeth have an intrinsic capability to regenerate, a process that is driven by dental pulp stem cells (DPSCs) that replenish the dental pulp, including the dentin-producing cells called odontoblasts. https://medicalxpress.com/news/2026-05-stem-cells-root-tooth-aging.html Thu, 21 May 2026 11:00:14 EDT news698511718 A study from the Hebrew University of Jerusalem has identified a significant link between maternal care and lifelong oral health. Led by Prof. Avi-Hai Hovav and the DMD/Ph.D. student Reem Naamneh from the Faculty of Dental Medicine at Hebrew University, the team discovered that maternal antibodies do not just offer a temporary shield for newborns but actually program the offspring's immune system to fight oral diseases well into adult life. The research is published in the journal Nature Communications. https://medicalxpress.com/news/2026-04-maternal-antibodies-pregnancy-lifelong-defenses.html Wed, 29 Apr 2026 18:20:08 EDT news696697202 People who experienced early socioeconomic disadvantage (SED) were 12–16% less likely to go for preventive dental visits during both adolescence and adulthood, a new University of Bristol study has found.
