The Mediterranean diet is broadly recognized for its advantages, from enhancing heart health to maintaining cognitive function. Recent research now indicates it may also help safeguard against gum disease.Diet’s Role in Oral Health“Gum disease is often seen as purely a hygiene issue, but our findings suggest that what we eat can play a supporting role,” Luigi Nibali, PhD, senior author and a professor of Periodontology at King’s College London, cited Health. “A balanced, plant-rich diet may help reduce inflammation and support healthier gums alongside regular oral care.”
In a study published in the Journal of Periodontology, researchers examined data from 200 hospital patients, that includes dental exams, blood tests, and diet questionnaires, gathered through the King’s College London Oral, Dental and Craniofacial Biobank. Findings indicated that participants who strictly followed the Mediterranean diet experienced better gum health and lower levels of inflammation. In contrast, individuals who did not maintain this diet showcased worse gum health, severe gum disease, and higher inflammation, especially those consuming an increased amount of red meat.
Research LimitationsWhile the results add to earlier studies connecting the Mediterranean diet to enhance oral health, researchers warn that the study only demonstrates an association, not causation. An extensive sample size would have offered stronger evidence.Gum Disease in the U.S.Gum disease, or periodontal disease, is prevalent in the United States, impacting nearly 2 in 5 adults aged 30 and above. The condition is mainly caused by inadequate brushing and flossing, which enables plaque accumulation along the gumline. This plaque triggers inflammation as the body tries to fight off harmful bacteria, a process where diet may impact outcomes.

“The Mediterranean diet is rich in anti-inflammatory nutrients, like antioxidants, fiber, and healthy fats, which may help modulate the body’s immune response,” Nibali stated. “On the other hand, diets high in processed foods and red meats tend to promote inflammation, which can aggravate gum tissue and contribute to disease progression.”Practical Advice for Gum HealthAlthough existing evidence does not definitively prove that a Mediterranean diet will prevent gum disease, it may serve as a beneficial strategy to minimize systemic inflammation. Beatriz Bezerra, DDS, PhD, associate clinical professor and director of the predoctoral program in the Section of Periodontics at UCLA School of Dentistry, cited, “Regular dental visits, daily brushing and flossing, along with other healthy habits that include, but are not limited to, an anti-inflammatory diet, can aid in reducing the onset and the severity of gum disease.”Disclaimer: The information provided in this article is intended for educational and informational purposes only and is not a susbstituion as medical advice.
