Hidden tooth-root infections may be linked to poorer blood sugar control, studies suggest

Evidence summarized in a May 15, 2026 report indicates that apical periodontitis—an infection around the tip of a tooth root that can be painless and go unnoticed—may contribute to low-grade systemic inflammation and be associated with worse blood sugar regulation. In observational research cited in the report, people treated with root canal therapy for these infections showed improved long-term blood sugar measures and lower inflammatory markers during follow-up, though researchers caution that causation has not been proven.
A small clinical trial found that short periods of calorie restriction lowered inflammation markers tied to gum disease. Researchers at King's College London led the study involving patients in Spain. The results suggest dietary changes could complement standard dental treatments.

A new analysis of primate teeth suggests that grooves once attributed to ancient tooth-picking may form naturally instead. Researchers also found no signs of a common modern dental issue in wild primates.
The Professional Regulation Commission has released the results of the November 2025 Licensure Examination for Dentists, with 1,282 out of 1,474 candidates passing.

Researchers at the University of Sharjah report that garlic extract mouthwash can provide antimicrobial effects comparable to chlorhexidine, the long‑standing gold standard in oral antiseptic rinses. A new systematic review highlights garlic’s potential as a natural alternative, though it may cause more discomfort even as it appears to offer longer‑lasting residual activity.
People with both cavities and gum disease had an 86% higher risk of ischemic stroke than those with healthy mouths, according to research published October 22, 2025, in Neurology Open Access. The two-decade study of 5,986 adults linked poor oral health to higher rates of major cardiovascular events, while emphasizing the findings show association, not causation.

A peer‑reviewed study in rats reports that moderate exercise combined with omega‑3 supplementation improved immune markers and limited bone loss in chronic apical periodontitis, an inflammatory infection at the tooth’s root tip often arising from untreated decay. The authors and research backers stress that human trials are needed to confirm clinical relevance.
