Oral health is often overlooked despite its crucial role in overall well-being. The mouth acts as a gateway to the body, with conditions affecting nutrition, speech, confidence and wider systemic health.
Historically, dentistry has focused on treating problems rather than preventing them, even though most oral diseases are preventable. As World Oral Health Day approaches on 20th March, Dr Maria Papavergos, known as The Lifestyle Dentist, is calling for greater emphasis on prevention, particularly through nutrition and daily care.
Widespread oral health challenges
Recent data highlights the scale of the issue. Around 41% of adults in the UK have untreated tooth decay, a rise from 28% in 2009 and a return to levels last seen in 1998. Nearly half of adults report experiencing at least one oral health impact in the past year. Among children, more than one in five five-year-olds in England have visible tooth decay, and tooth decay remains the leading cause of hospital admissions for those aged 5–9. The financial burden is also significant, with child tooth extractions costing the NHS more than £40 million annually.
There are approximately 10,825 new cases of mouth cancer in the UK each year. Inequalities persist, with oral health closely linked to deprivation. Brushing twice daily is reported by 69% of people in the most deprived areas, compared with 85% in the least deprived.
Nutrition and its role in oral and overall health
Nutrition plays a central role in maintaining both oral and general health, yet it is often overlooked. A balanced diet supports mental and physical performance while also protecting the mouth.
Around half of mouth cancer cases are associated with diets low in fresh fruit and vegetables, which provide antioxidants, vitamins and minerals that help protect against harmful cellular changes. In contrast, highly processed foods rich in refined carbohydrates are pro-inflammatory and linked to a higher risk of gum disease.
Gum disease itself is associated with broader health risks, including a threefold increase in the risk of diabetes and a causal role in the development of cardiovascular disease.
Dr Papavergos said: “The connection between the mouth and the rest of the body is indisputable with oral-systemic links being well established not only in terms of chronic inflammatory disease, but immunity and longevity too. It’s time to put the mouth on the map to health.”
Practical steps for better oral health
Experts recommend simple daily measures to improve oral hygiene and overall health. Brushing twice a day and cleaning between teeth using floss or interdental brushes remain essential. It is also advisable to wait at least an hour after consuming acidic foods before brushing to protect enamel. When brushing, individuals should spit out excess toothpaste but avoid rinsing immediately so fluoride can continue to protect the teeth.
Maintaining hydration is important to support saliva flow and a balanced oral microbiome. Reducing sugary foods and drinks can lower the risk of tooth decay, while increasing intake of anti-inflammatory foods such as oily fish, dairy products and leafy green vegetables can help strengthen teeth and bones. Regular dental visits, ideally every six months, are also recommended. In addition, targeted oral probiotics may support microbiome balance when used alongside a healthy diet.
Focus on the oral microbiome
Maintaining a balanced oral microbiome is increasingly recognised as key to preventing disease. This can be supported through diet, hydration, proper brushing techniques and the use of targeted probiotics.
Luvbiotics, a British oral care brand developed by microbiologists and dentists, promotes this approach by focusing on supporting beneficial bacteria rather than eliminating all microbes. Its range includes toothpastes, mouthwashes and oral health lozenges available through major retailers and online platforms.
Dr Papavergos, who has more than 10 years of clinical experience, advocates a holistic approach to dentistry that views the mouth as integral to whole-body health. She continues to emphasise the importance of prevention and education, particularly as campaigns for World Oral Health Day encourage simple steps to reduce preventable disease and improve overall health.
