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.

NewsA comparison of the efficacy of non-chemical versus chemical cleansers against Candida species on removable dental prostheses
A new review aims to systematically compare the efficacy of chemical and non-chemical denture cleansers in reducing Candida spp. on removable dental prostheses.
-
NewsNew biosensor offers early warning system for disease
Researchers have developed a tissue-adhesive sensor for real-time oral health monitoring to combat long-term issues such as gum disease and tooth loss.

NewsHow bacteria in the mouth may offer new clues to cognitive dysfunction in people with schizophrenia
An association between oral microbiota and cognitive performance in schizophrenia has been reported by researchers. The study shows that lower oral microbial diversity is associated with poorer cognitive function, with specific predicted microbial metabolic pathways potentially linked to this relationship.
-
NewsHow genes influence the microbes in our mouths
A new study has found human genetic factors that influence the oral microbiome and may increase risk of cavities and tooth loss in some people. Analysis of the now largest collection of oral microbiome profiles reveals interactions between human and bacterial DNA.
-
NewsBreath carries clues to gut microbiome health
Researchers have shown that disease-associated bacteria in the gut can be detected through exhaled breath. They found that chemicals released by gut microbes and captured from the breath of children and mice can reveal the composition of the bacteria living in the intestines.
-
NewsOral bacterium may promote breast cancer development and spread
Researchers found that Fusobacterium nucleatum, an oral bacterium commonly associated with periodontal disease, can promote breast cancer initiation, tumor growth and spread by inducing DNA damage and altering cancer cell behavior.
-
NewsAltered microbiome: Oral bacteria play a role in chronic liver disease
A new study shows that identical bacterial strains occur in both the mouth and gut of patients with advanced chronic liver disease and also reveals a mechanism by which oral bacteria affect gut health. The researchers also found that this process coincides with worsening liver health.

NewsA new ally against tooth decay: Arginine offers sweet relief
A new human clinical trial finds arginine can prevent caries due to bacterial plaques by reducing the acidity, altering the plaque structure and reducing harmful bacteria in the plaques.
-
NewsGut bacteria changes at the earliest stages of inflammatory bowel disease
People newly diagnosed with the most common IBD subtypes, Crohn’s disease and ulcerative colitis, lose beneficial anaerobic bacteria that help with digestion of complex carbohydrates. Patients instead experience a rise in oxygen-tolerant bacteria from the mouth that travel in the gut.
-
NewsOral bacterium tied to disability severity in multiple sclerosis
A research team has conducted a study with findings that suggest a potential association between the relative abundance of Fusobacterium nucleatum (F. nucleatum), a bacterium found in the mouth, and disease severity in multiple sclerosis (MS) patients.

NewsCloves and miswak: Antimicrobial effects of Syzygium aromaticum and Salvadora persica against common pathogens in vitro
Clove essential oil (CEO) derived from Syzygium aromaticum and miswak (Salvadora persica) contains bioactive compounds with antimicrobial properties. This study aimed to evaluate the in vitro antimicrobial efficacy of CEO, miswak, and their combination against key peri-implantitis pathogens.
