NewsFoods containing heat-inactivated bacteria help reduce gum bleeding and improve inflammatory conditions
Continuous consumption of foods containing heat-inactivated Lactiplantibacillus pentosus can help reduce gum bleeding, report researchers. These postbiotic foods can improve inflammatory conditions and enhance gum health in adults with mild gingivitis.

NewsCohabitating people share about a quarter of their gut and oral microbiota
People who live together share more oral and gut microbes with each other than with other people in their communities, according to a study. Researchers also found a link between more transmissible microbes and health, particularly type 2 diabetes.

NewsFasting-mimicking diet reduces gum disease inflammation
A new study highlights how lifestyle modifications could be important alongside plaque control in managing gum disease. While fasting has been linked to reduced inflammation around the body, this is the first to establish a relationship with gum disease too.

NewsWhat dental calculus can tell us about the oral microbiomes of ancient Japan
Microbe DNA from ancient dental calculus offers insights into the past oral microbiomes of the Japanese people, including the phylogeny of the periodontal disease-associated archaeon, Methanobrevibacter oralis.

NewsDentistry researchers testing oral bacteria transplants to cure bad breath
To rebalance the oral microbiome and cure chronic halitosis, researchers are embarking on a first-of-its-kind experiment. These clinical trials transplant bacteria and other microbes from healthy donors into patients with halitosis. If successful, the healthy microbiota will crowd out the bad and patients’ bad breath will improve.

NewsThe road to better health requires a map of the microbes in your mouth
Different parts of your mouth have entirely different bacterial communities, reveals a new microbial map. Researchers believe mapping these microbial niches will provide a census of the good bacteria present in the mouth and help to develop targeted therapies, such as probiotics, to maintain oral health and prevent disease.

NewsBiomaterial made from jackfruit latex is a promising treatment for periodontitis
Researchers have developed a biomaterial containing jackfruit latex, pomegranate peel extract, and simvastatin that shows promising efficacy in treating periodontitis. This chronic inflammatory disease of infectious origin leads to the progressive destruction of the tissues supporting the teeth, resulting in bone resorption and loss of attachment.

NewsWhy antibiotics fail against a common dental implant disease
A study of peri-implantitis found that bacteria corrode implants, causing them to shed microscopic titanium particles into the surrounding tissue. Those particles hijack the immune cells sent to clear the infection and lock them into a state of inflammation that destroys the jawbone they are supposed to protect.

NewsModern medicine makes gut microbial diversity plummet
Even minimal exposure to modern medicine can rapidly change the human microbiome. Researchers reveal that the gut microbes of remote Amazonian Indigenous communities began shifting toward patterns more commonly seen in urban, industrialized populations after only a few medical visits.

NewsOral spray neutralizes smelly dog breath with plant extracts
An oral spray derived from molasses, a by-product of sugar cane refining, reduced bad smells, odor-producing compounds and harmful bacteria from 10 dogs’ mouths.

NewsInvisible smart bug fights gum disease
Current treatments for periodontitis often fail because they cannot simultaneously eliminate stubborn bacterial biofilms and calm the runaway inflammation that follows. Now researchers have engineered a living bacterium that does both, in the right order.

NewsResearchers fight oral cancer with bioengineered chewing gum
Research shows that antiviral and antibacterial chewing gums reduce the levels of three microbes linked to worse outcomes in oral cancers, paving the way for more effective and affordable therapies.

NewsOral-gut axis points to salivary biomarkers for early gastric cancer detection
A recent study has identified distinct microbial “signatures” within the oral cavity and gut that serve as robust biomarkers for the early detection of gastric cancer (GC). Research shows how specific lactic acid-producing bacteria (LAB) migrate from the mouth to colonize the gastrointestinal tract.

NewsImproving oral care more than halves hospital-acquired pneumonia risk, major trial finds
A landmark trial presented at ESCMID Global 2026 shows that improving oral hygiene for hospital patients can reduce the risk of non-ventilator-associated hospital-acquired pneumonia (NV-HAP) by 60%.

NewsLuis Daniel Sansores España named recipient of the 2026 IADR Norton Ross Fellowship
The International Association for Dental, Oral, and Craniofacial Research (IADR) has announced Luis Daniel Sansores España, IADR Chilean Division, as the 2026 recipient of the IADR Norton Ross Fellowship.

NewsWorld-first discovery of noma-linked bacteria opens path to early diagnosis and prevention
Researchers have identified a bacterium strongly associated with noma disease, marking a major step towards earlier diagnosis and more effective treatment. They uncovered a previously undescribed species of Treponema bacteria, which may be responsible for the disease.

NewsLemongrass essential oil may target bacteria even more effectively than conventional antibiotics, research suggests
Lemongrass essential oil can be even more effective than traditional antibiotics against some Streptococcus bacteria under certain conditions, new research to be presented at MLSFF26 has found.

NewsHow periodontitis-linked bacteria accelerate osteoporosis-like bone loss through the gut
Researchers reveal that salivary bacteria from gum disease alter gut metabolism, driving osteoclast activity and systemic bone loss. They analyzed salivary microbiota from individuals with advanced periodontitis and compared them with samples from periodontally healthy donors.

NewsBacteria found in mouth and gut may help protect against severe peanut allergic reactions
One of the big mysteries in food allergy is why two people with similar levels of peanut specific antibodies can react so differently. A new study shows for the first time how gut bacteria break down parts of an allergenic food and influence how a person reacts to peanuts.

NewsResearchers find a gentler way to treat aggressive gum disease
Researchers have discovered that the primary bacterium driving gum disease carries an internal “genetic brake” that controls its own aggression. By locking this brake in place, future treatments could silence the pathogen while leaving beneficial bacteria untouched.
