Antioxidant in red and pink produce linked to lower severe gum disease risk

Lycopene is found in red and pink fruits and vegetables such as tomatoes, watermelon and grapefruit. (iStock)

A natural antioxidant called lycopene, found in red and pink fruits and vegetables such as tomatoes, watermelon and grapefruit, has been associated with a reduced risk of severe periodontitis in older adults, according to a new observational study published in The Journal of Nutrition, Health & Aging. Periodontitis is a chronic inflammatory gum disease that … Read more

U.S. dental practices face a fiscal squeeze heading into 2026 — here are the top 10 signals

“Looking ahead to 2026, continued uncertainty is a key theme,” says the ADA. (iStock)

American Dental Association (ADA) says new data from its Health Policy Institute (HPI) show U.S. dental practices remain under sustained financial pressure, driven by softening demand for care and rising operating costs. The Q4 2025 analysis combines dentist survey data with federal economic indicators to track confidence, patient demand, staffing trends, reimbursement and investment intentions … Read more

Natural amino acid in saliva shows promise in reshaping harmful dental plaque

Researchers say arginine could be safely incorporated into toothpastes or oral rinses, particularly for patients at higher risk of cavities — including children. (iStock)

Researchers testing a naturally occurring amino acid found in saliva say it could help make dental plaque less damaging — and potentially reduce the risk of cavities before they start. In a small human clinical trial, scientists from Aarhus University found that arginine, an amino acid already present in the mouth, can alter dental plaque … Read more

Pharmacological management of acute dental pain in pediatrics: A summary of evidence-based clinical practice guidelines from the ADA

Girl holding cheek while sitting in dental chair showing sign on pain to female dentist. Child experiencing discomfort during clinic visit. Woman dentist observing young patient appears to be suffering from a severe toothache or jaw discomfort.

Acute dental pain in children can stem from various conditions, such as extractions, pulpitis, or apical abscesses. Managing this pain effectively is crucial for improving the child’s comfort and reducing distress for both the patient and their caregivers.

Researchers find Atlantic wolffish teeth contain rare material that shrinks under pressure

The Atlantic wolffish is known for its powerful bite, capable of crushing hard-shelled prey. (iStock)

Researchers at Hebrew University of Jerusalem have discovered that the Atlantic wolffish’s teeth contain a rare internal material that contracts in every direction when compressed — a mechanical behaviour almost never seen in natural mineralized tissues. The study, led by Prof. Ron Shahar of the Koret School of Veterinary Medicine at Hebrew University, found that … Read more

Sustaining the smile: The role of the general dentist in retention and occlusal stability

With great care, orthodontic retainers would serve for a long time without any major issues. However, in some cases, the failure to notice the clinical problems early on results in functional issues that would require a comprehensive orthodontic treatment to correct it.

Sugarcane-based artificial saliva may protect teeth after head and neck radiation

The CANECPI-5 mouthwash is derived from a sugarcane protein. In laboratory testing, the protein bound directly to tooth enamel and significantly reduced demineralization. (iStock)

An artificial saliva developed from a sugarcane protein could help protect teeth in patients treated for head and neck cancer, a group at high risk of severe oral complications following radiotherapy. Researchers at the University of São Paulo’s Bauru School of Dentistry have developed a saliva substitute containing CANECPI-5, a protein extracted from sugarcane and … Read more

From mining to dentistry, Northwestern Ontario Association applauds new credential rules

Labour shortages across Northwestern Ontario could ease as the Northwestern Ontario Association backs new Ontario credential rules affecting sectors from mining to dentistry. (iStock)

 NORTHWESTERN ONTARIO — Representatives for the region’s municipalities are throwing their support behind new provincial rules they say can help fill needed labour gaps. The Northwestern Ontario Municipal Association, or NOMA, is backing new “as-of-right” rules the Ford government said went into effect at the beginning of the new year. They aim to speed up … Read more

Nine U.S. universities launch $17M NIH study to advance TMD treatment

Five University at Buffalo researchers are involved in the study, known as the Collaborative for REsearch to Advance TMD Evidence (CREATE), which forms part of the broader TMD IMPACT research network. (iStock)

Nine U.S. universities are collaborating on a five-year, $17-million research initiative aimed at improving the understanding, diagnosis and treatment of temporomandibular disorders (TMDs), following a major grant from the National Institutes of Health (NIH). The multi-institution project, funded through the National Institute of Dental and Craniofacial Research (NIDCR), brings together researchers across dentistry, medicine, neuroscience, … Read more

Tooth loss — not diet — linked to cognitive decline in aging mice

Mice that lost their molars showed significant memory impairment — even when their protein intake matched that of control animals. (iStock)

A study published in Archives of Oral Biology suggests that tooth loss — rather than reduced protein intake — plays a central role in driving cognitive decline in aging male mice, underscoring a growing link between oral function and brain health. Low protein intake has long been linked to frailty, muscle loss and cognitive impairment … Read more

Study links periodontal bacterium to multiple sclerosis disability severity

The Hiroshima University researchers note that MS prevalence in Japan has risen over recent decades, a trend thought to be influenced by environmental changes. (iStock)

A Hiroshima University study has found that higher levels of the periodontal bacterium Fusobacterium nucleatum in the mouth were associated with greater disability in people living with multiple sclerosis (MS), though the researchers caution the findings do not establish cause and effect. The cross-sectional observational study, published in Scientific Reports, analyzed tongue-coating samples collected from … Read more

A year in review: Why 2025 showed oral health matters far beyond the mouth

"Specialists who deal with inflammatory diseases are starting to recognize the connections to oral health,” says Dr. Thomas Van Dyke. (iStock)

The year 2025 may be remembered as the moment oral health moved beyond the mouth — and into the centre of systemic disease prevention. As Dr. Thomas Van Dyke noted at SmileCon in October, dentistry and medicine have historically evolved on parallel tracks. But in 2025, a growing body of research brought those worlds closer … Read more
