Oral Microbiome: The New Frontier in Longevity and Health

In the early 2020s, the wellness industry became captivated by the concept of the microbiome, with a particular focus on gut health. However, recent research suggests that the secrets to longevity may also be found within the mouth. The oral microbiome, the second largest microbiota in the human body, comprises over 700 different species of bacteria. Its diversity impacts much more than just oral hygiene; it plays a significant role in overall health, influencing conditions such as heart disease and cognitive function.

Dr Sam Jethwa, a leading dentist and president of the British Academy of Cosmetic Dentistry, emphasizes the importance of maintaining a balanced oral microbiome. “Maintaining balance in the oral microbiome is vital for healthy gums, preventing cavities and tooth decay, but it is also linked to our overall health,” he explains. Dr Rizwan Mahmood, co-founder of Ruh Dental at Harrods, adds, “When this delicate ecosystem is disrupted — what we call dysbiosis — harmful bacteria can flourish. These bacteria don’t just stay put. They can enter the bloodstream via inflamed gums and contribute to systemic inflammation, which is increasingly linked to chronic conditions.”

The Oral Microbiome and Systemic Health

The connection between oral health and systemic diseases is becoming increasingly evident. The British Heart Foundation has published research indicating that 69% of individuals with gum disease have a higher likelihood of developing type 2 diabetes, which subsequently raises the risk of heart disease. Moreover, emerging studies suggest that harmful oral bacteria, which can cause gum disease, are also linked to Alzheimer’s disease.

Dr Mahmood succinctly states, “In short, a healthy mouth sets the stage for a healthier you.” This insight underscores the importance of oral health in the broader context of overall well-being.

Promoting a Healthy Oral Microbiome

The market for products that support the oral microbiome is expanding rapidly, with oral probiotics becoming a popular new category. However, both Dr Jethwa and Dr Mahmood stress the importance of mastering basic oral hygiene practices. “Looking after your mouth’s microbiome means doing more than just brushing vigorously twice a day,” advises Dr Mahmood. “It’s about gentle, effective cleaning, avoiding excessive use of harsh mouthwashes that can wipe out good bacteria, and being mindful of sugar intake, which fuels the harmful bugs.”

Dr Jethwa highlights often-overlooked areas in oral care, such as brushing the gum line, tongue, and inside the cheeks, as well as flossing at least once a day with interdental brushes. “Almost half the surface area of your teeth is between them, and if you’re not cleaning there, plaque builds up, putting you at risk for gum disease and decay,” Dr Mahmood warns.

Modern Dental Care: Risks and Innovations

The rise in popularity of cosmetic dentistry has led to a projected global market value of over £45 billion by 2026. However, this trend comes with its own set of risks. Dr Mahmood cautions against the use of mail-order or DIY aligners, which can damage tooth roots or worsen gum health, and notes that at-home whitening can increase sensitivity and weaken enamel.

Dr Jethwa also warns about “Turkey teeth,” often crowns rather than veneers, which involve drilling down natural teeth and can lead to sensitivity, pain, and infection. “Ensuring you have any tweakments on your mouth performed by a trusted, registered professional is essential,” he advises.

Meanwhile, a new wave of dental care products focuses on oral health with longevity in mind. Suri’s hygienic electric toothbrush, for example, is gaining popularity for its UV-light clean case that kills 99% of bacteria in a minute. Additionally, new toothpastes with natural ingredients and appropriate fluoride levels are emerging. Products like Tooth Angel in Cinnamon Mint and Selahatin’s Steam Will Rise are leading the charge.

The Path Forward

An increased interest in oral health reflects a broader understanding of its impact on overall well-being. Regular dental check-ups and updating your at-home dental care kit can significantly contribute to maintaining a healthy oral microbiome. As research continues to uncover the connections between oral and systemic health, the emphasis on comprehensive oral care is likely to grow, promising not only healthier smiles but also improved longevity.
