Good oral health can reduce cancer risk, improve overall health: AIIMS Delhi study
New Delhi: Oral healthcare plays a significant role in enhancing health-related outcomes, including those associated with cancer, researchers from AIIMS Delhi said, underscoring the necessity of integrating oral care practices not only at the primary level but throughout all health management. Emerging evidences indicate that poor oral health is closely associated with several health problems, including cardiovascular disease, diabetes, adverse pregnancy outcomes and Alzheimer's disease, oncologists Dr Abhishek Shankar and Dr Vaibhav Sahni from All India Institute of Medical Sciences (AIIMS), Delhi said in an article published in The Lancet Regional Health - Southeast Asia earlier this month. Oral hygiene has been implicated in cancer risk and its prediction, particularly in head and neck cancers (HNC). The current literature also suggests a link between periodontal disease, also known as gum disease, and cancers of the digestive tract, prostate, breast, pancreas, oropharynx, uterus, and lungs. The international head and neck cancer epidemiology (INHANCE) consortium, through a pooled analysis of 13 studies involving 12,527 controls and 8,925 HNC cases, reported that good oral hygiene (defined by annual dental visits, fewer missing teeth and daily tooth-brushing) was associated with a modest reduction in the risk of HNC, the researchers said. Presence of pathogenic oral bacteria such as Porphyromonas gingivalis and Prevotella intermedia has been shown to elevate cancer incidence and adversely affect overall survival whether with specific-cancer or disease-free, they said. Oral health is crucial in the context of cancer therapy. A recent systematic review concluded that radiotherapy (RT) to the head and neck region significantly alters the oral microbiome, typically reducing beneficial bacteria while increasing potentially harmful species, leading to post RT complications, the research suggested. Patients with severe periodontal disease undergoing intensity-modulated radiotherapy (IMRT), with or without chemotherapy, have shown higher susceptibility to post-treatment bone healing complications, the researchers said. These findings make it imperative to maintain optimal oral hygiene before, during and after RT, given its role in influencing survivorship outcomes, they added. Data from the CHANCE study revealed that routine dental visits over the past 10 years were associated with reduced cancer mortality, according to the research. Dr Shankar and Dr Sahni, however, pointed out that there is a dearth of original data from Southeast Asia reporting on the association between oral health and cancer, as most original studies tend to limit their scope to epidemiological findings. "It is abundantly clear that oral healthcare plays a significant role in enhancing health-related outcomes, including those related to cancer survivorship . This evidence underscores the necessity of integrating oral health practices not only at the primary care level but throughout all healthcare settings," the doctors said. Efforts should focus on innovating and implementing point-of-care diagnostics in oral health that are evidence-based, economical, validated, and offer sufficient sensitivity and specificity, they stressed. The researchers stated that the World Health Organisation (WHO) - South East Asia Region (SEAR) could benefit from public health initiatives to improve oral health. Researchers also pitched for supervised tooth-brushing programmes for children alongside sensitising teachers and families regarding the importance of oral health and providing free toothbrush and toothpaste to foster behavioural change. In England, supervised tooth-brushing programmes for children have proven to be an economical intervention, reducing health-related inequalities and tooth decay, they said. "Implementing a similar programme in India may provide comparable oral health benefits and, given its effectiveness in resource-constrained settings, is particularly encouraging," they said. Various operational challenges like the economic viability of families, leading to unintentional health neglect, low priority to oral health, inadequate incentives and motivation among teaching staff to ensure their effective involvement. Oral health has been shown to significantly influence cancer outcomes and survivorship; however, research in this domain could be more relevant if supported by data from the SEAR, the researchers stated. Public health interventions like labels of 'nutrition' and 'sugar warning' may assist consumers in making informed decisions. It is essential to enforce policies against proxy advertisements for tobacco products while also implementing measures to prohibit the use of likable characters promoting sugar-laden snacks and beverages to children, they said.

New study links oral hygiene to cancer risk: 10 tips to protect your oral health
We often view oral hygiene as a cosmetic habit, important for white teeth and fresh breath, but new research suggests it may be far more vital to our health. A recent commentary in The Lancet Regional Health, Southeast Asia links poor oral hygiene to a higher risk of cancer, especially in head and neck cases. Professionals from AIIMS urge a shift in focus: from daily brushing to broader public health efforts like school-based dental care and stricter sugar marketing regulations. As cancer rates rise in Southeast Asia, maintaining good oral health could be a simple yet powerful tool for prevention and survival. What the study says: Link between oral hygiene and cancer outcomes In a commentary published in The Lancet Regional Health , Southeast Asia, AIIMS oncologists Dr Abhishek Shankar and Dr Vaibhav Sahni discussed the rising body of evidence linking oral bacteria such as Porphyromonas gingivalis and Prevotella intermedia with higher cancer incidence and poorer survival outcomes. The researchers noted that routine dental checkups are associated with reduced cancer mortality, underlining that oral hygiene should be integrated into standard oncology care. With the cancer burden increasing in Southeast Asia and preventative care often neglected, they stress the urgent need for structured public health programmes that prioritise oral health. Some of the interventions they proposed include School-based toothbrushing programmes Oral rinse-based point-of-care testing for gum disease detection Distribution of free toothbrushes and toothpaste Health warnings on high-sugar food packaging Incentives for educators and families to promote oral care Dr Shankar noted that 'oral healthcare plays a significant role in enhancing health-related outcomes, including those related to cancer survivorship.' by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Many Are Watching Tariffs - Few Are Watching What Nvidia Just Launched Seeking Alpha Read More Undo His colleague, Dr Sahni, also warned against the marketing of sugary foods using cartoon characters, calling for region-specific research to better inform prevention strategies. 10 Tips to maintain your oral hygiene Brush your teeth twice a day Brushing your teeth in the morning and before bed is crucial. Night brushing removes plaque, food debris, and bacteria that build up during the day, reducing your risk of tooth decay and gum disease. Use proper brushing technique A rushed brushing job can leave plaque behind. Use a soft-bristled brush in gentle, circular motions for at least two minutes. Avoid aggressive scrubbing, which can erode enamel and damage gums. Don't forget your tongue Bacteria can accumulate on your tongue, contributing to bad breath and oral health problems. Gently brushing your tongue every time you brush your teeth helps keep your whole mouth clean. Choose fluoride toothpaste Fluoride is essential for strengthening tooth enamel and protecting against decay. Always choose a fluoride toothpaste, regardless of the brand or flavour. Floss daily Flossing helps clean areas your toothbrush can't reach between the teeth and under the gumline. Daily flossing reduces plaque buildup and lowers your risk of cavities and gum disease. Rinse with a mouthwash A fluoride-based mouthwash can further protect your teeth and freshen your breath. Use it at a different time of day than brushing, such as after meals, to avoid rinsing away fluoride from toothpaste. Drink plenty of water Water, especially if fluoridated, helps rinse away food particles and maintain saliva flow, which is vital for neutralising harmful acids in the mouth. Limit sugary and acidic foods Frequent consumption of sugar and acidic drinks like sodas, tea, and citrus can erode enamel. Try to reduce their intake and rinse your mouth with water after consuming them. Schedule regular dental checkups Visit your dentist every six months for a professional cleaning and exam. Dentists can detect early signs of decay, gum disease, or other issues before they become serious. Maintain a complete oral care routine Good oral health involves consistent habits. Brushing, flossing, tongue cleaning, and regular dentist visits form the foundation of long-term dental wellness.

Oral health key for cancer care, boosting survival rates: AIIMS
Oral health plays a significant role in cancer care, and increasing survival rate, according to researchers from the All India Medical Science (AIIMS). The presence of pathogenic oral bacteria such as Porphyromonas gingivalis and Prevotella intermedia has been shown to elevate cancer incidence and adversely affect overall cancer-specific and disease-free survival. In a comment published in the journal, The Lancet Regional Health - Southeast Asia, oncologists Dr. Abhishek Shankar, and Dr. Vaibhav Sahni from AIIMS stated that urged the need to boost public health initiatives as oral health can significantly influence cancer outcomes and survivorship. 'It is abundantly clear that oral healthcare plays a significant role in enhancing health-related outcomes, including those related to cancer survivorship. This evidence underscores the necessity of integrating oral health practices not only at the primary care level but throughout all healthcare settings,' the researchers said in the paper. The oncologists also cited several global studies that cited the link between oral health and cancer, particularly in head and neck cancers (HNC). The studies showed that routine dental visits over the past 10 years were associated with reduced cancer mortality. They urged for initiatives such as the toothbrushing programmes for boosting oral care and implementing oral mouthrinse- based point-of-care 3 (PoC) testing for early diagnosis of periodontal disease. 'We tried to emphasise the importance of oral health in cancer care particularly for the Southeast Asia region to promote awareness and policy-level decision-making,' Dr Shankar, Assistant Professor of Radiation Oncology at AIIMS, Delhi, told IANS. 'We want public health initiatives to be structured around oral health such as school toothbrushing programmes stand to aid not only the population at large but the exchequer as well,' he added. Further, the paper suggests sensitising and incentivising teachers and families regarding the importance of oral health, alongside providing free toothbrush and toothpaste samples to help foster behavioural change. In addition, public health interventions like nutrition and sugar warning labels may assist consumers in making informed decisions. 'Prohibiting sugar-laden foods marketed using likable characters needs to be taken up seriously at a policy level,' Dr Sahni, Scientist of Radiation Oncologat, AIIMS Delhi, told IANS. He highlighted the systemic and public health importance of oral health in cancer-related outcomes as well as emphasise the need for relevant data. The expert also called for proper studies in Southeast Asia and not a simple translation of Western findings to the region's context.

Oral Health Could Shape Cognitive Decline, and Ways to Improve It
'Maintaining good oral hygiene, addressing dental issues early, and supporting a healthy oral microbiome may influence brain health more than we ever realized,' Joanna L'Heureux, a researcher at the University of Exeter Medical School, told The Epoch Times. The oral microbiome—the community of bacteria, fungi, and viruses that live in our mouths—can influence brain health in multiple ways. Some microbial species are linked to better memory and focus, while others have been tied to cognitive decline and genetic risk factors for dementia. Simple, inexpensive habits like brushing, flossing, and even what we eat can help tip the balance in our favor. The Link to Cognitive Health When oral health is compromised, harmful bacteria can enter the bloodstream through inflamed gums after chewing or brushing. An overgrowth of harmful bacteria, A healthy immune system typically clears bacteria out, but older adults with weakened immunity may struggle to eliminate harmful bacteria. Over time, bacteria and inflammation can disrupt the blood-brain barrier, leading to neuroinflammation, the buildup of toxic proteins like amyloid-beta and tau, and changes in blood vessels—all of which are Another way oral health appears to influence brain function is through the nitrate–nitrite–nitric oxide (NO) pathway. Beneficial oral bacteria help convert dietary nitrate into nitrite, which the body then turns into nitric oxide—a molecule essential for blood flow, nerve signaling, immune defense, and memory. As we age, the body naturally produces less nitric oxide, which may contribute to cognitive decline. Related Stories 9/23/2024 4/27/2025 A January This raises the possibility that early changes in the oral microbiome could act as warning signs for cognitive decline—and an opportunity to intervene before symptoms begin, said L'Heureux, one of the study's researchers. Early Signs How can you tell if your oral bacteria might be affecting your brain? There are a few red flags to watch for, Angel Planells, registered dietitian nutritionist, told The Epoch Times. Chronic gum issues—like gingivitis or periodontitis—persistent bad breath, bleeding or receding gums, and frequent mouth infections can all signal an imbalance in the oral microbiome. These are signs that harmful bacteria may be taking over. Some dentists and specialty labs now offer oral microbiome testing, which can detect overgrowths of these harmful microbes, he added. Specific patterns in oral bacteria, such as higher levels of Prevotella intermedia, might also serve as early warning signs for dementia risk. A 2020 Finally, subtle, unexplained cognitive changes like memory lapses or brain fog, paired with poor oral health hint at a deeper connection, Planells said. How to Support a Healthier Oral Microbiome 'Targeting the oral microbiome could be a promising way to help prevent cognitive decline,' L'Heureux said. That starts with good oral hygiene. Regular brushing, flossing, and dental check-ups go a long way toward keeping harmful bacteria in check, she said. A 2020 Diet matters, too. Cutting back on sugar and refined carbs can reduce the fuel that harmful bacteria thrive on, Planells said. At the same time, loading up on fibrous fruits and vegetables helps sweep away oral plaque and feeds the beneficial bugs. Leafy greens and beets, which are high in dietary nitrates, may be especially helpful. These foods support the growth of helpful bacteria that boost nitric oxide, L'Heureux said. Polyphenol-rich foods like berries, green tea, and dark chocolate can help suppress harmful bacteria, Planells said. And don't forget fermented foods like yogurt, kefir, and sauerkraut. While they benefit the gut microbiome, they may also indirectly support the oral microbiome by enhancing immune function and microbial diversity. Planells also recommends staying well-hydrated to keep saliva flowing, since it contains natural antimicrobial compounds. Avoid smoking and limit alcohol, both of which can disrupt the microbiome. Managing stress and getting enough restorative sleep are also key, as both impact immunity and oral health. 'And remember, not all bacteria are bad,' Planells said. 'A healthy oral microbiome is diverse. Using mouthwashes with strong antiseptics, alcohol, or harsh chemicals can wipe out both the good and bad bacteria, disrupting that balance.' What About Genes? Is it all about oral hygiene and bacteria, or do our genes have a say too? L'Heureux's study found that people with mild cognitive impairment who carried the APOE4 gene had higher levels of harmful oral bacteria linked to dementia. 'Our genes might play a role in shaping which bacteria thrive in our mouths, and that, in turn, could influence brain health,' L'Heureux said. It's still unclear whether APOE4 directly alters the mouth's environment or whether it's part of a broader genetic influence on the microbiome, she added.
