A Scottish dentist is urging both patients and practitioners to adopt everyday lifestyle habits that support the mouth and the body, arguing that nutrition, movement and stress reduction can make a measurable difference to oral health.

Dr Maria Papavergos sets out her approach in a study published in the British Dental Journal. Her work draws on her combined experience as a dentist and yoga teacher, emphasising the links between oral health, immunity, inflammation and longevity.

She argues that the traditional focus on brushing and flossing overlooks the wider lifestyle factors that shape the oral microbiome, the community of bacteria that influences gum health, disease risk and wider physiological functions.

“Oral diseases are largely preventable,” she explains. “If we look beyond smoking and alcohol, we find that diet, movement, and stress management all have profound effects on the mouth, and the mouth, in turn, influences the rest of the body.”

Research supports the close relationship between oral health and systemic disease. Gum disease has been associated with increased risks of cardiovascular disease and diabetes, while a balanced oral microbiome can help regulate blood pressure and reduce inflammation. Dr Papavergos argues that these connections highlight the need for preventive measures that work through everyday habits.

How lifestyle choices influence the oral microbiome

Dr Papavergos outlines several areas where simple behaviour changes can strengthen the oral environment:

• Nutrition and the oral microbiome. Prebiotic and probiotic foods such as leafy greens, yoghurt and kefir can support beneficial bacteria and lower the risk of gum disease, cavities and cardiovascular problems.
• Dietary nitrates and cardiovascular health. Vegetables including beetroot and spinach fuel nitric oxide production through oral bacteria. Studies show that nitrate-rich diets increase health-promoting bacteria and improve blood pressure and exercise performance.
• The role of omega 3. Oily fish can reduce inflammation in gum tissue. Omega 3 fatty acids have well established anti-inflammatory effects that may slow gum disease progression.
• Movement and mindfulness. Exercise can reduce inflammatory markers, while yoga and breathwork help manage cortisol spikes that worsen gum disease. Chronic stress disrupts the oral microbiome and weakens immune responses in the mouth.

A mouth-first approach to long-term health

Dr Papavergos encourages both patients and dental teams to adopt what she describes as a “mouth-first” approach to wellness. She highlights that the mouth serves as an entry point for many processes that influence overall health. Beneficial oral bacteria convert dietary compounds into substances such as nitric oxide, which supports vascular function. Disruptions caused by poor diet or high stress can shift this balance and promote harmful bacteria linked to periodontitis.

“Your mouth is the gateway to your body,” she says. “By nourishing it with the right foods, movement, and mindful practices, we can build resilience not only in oral health but in overall wellbeing.”

Her advocacy reflects a wider shift towards prevention in dental care. Oral diseases affect billions worldwide and remain largely avoidable. Established research shows that probiotic-rich foods support beneficial bacteria, nitrate sources like beetroot contribute to cardiovascular protection through oral conversion, and stress reduction techniques help lower cortisol-linked inflammation.
