The Diary Of A CEO with Steven Bartlett
Hosted by Steven Bartlett
Written by a model from the transcript; not yet reviewed.
Steven Bartlett interviews Victoria, a dentist who runs The Health Society clinic in central London, about the oral microbiome and its connection to systemic health. Victoria explains that Fusobacterium nucleatum, a specific oral bacterium, has been shown to accelerate tumour growth in mice and is linked to colorectal and breast cancer, though she cautions against calling it causal yet. She describes a pending study where an antibiotic targeting only that bacterium will be given to colorectal cancer patients to test whether it slows progression.
The conversation covers practical oral care: why sugar in hot tea is worse than eating a biscuit, the "sugar attack" principle of consuming all sugar at once rather than sipping over time, why you should never brush immediately after acidic or sugary foods, and why rinsing after brushing wastes the toothpaste. Victoria demonstrates brushing technique on a tooth model, explains why electric toothbrushes outperform manual ones (the average person brushes for 20–30 seconds, not the recommended two minutes), and discusses safe whitening, probiotics for the oral microbiome, and the use of straws to bypass teeth when drinking acidic or sugary beverages.
Oral Bacteria Linked to Tumour Growthinsight
Victoria explains that Fusobacterium nucleatum accelerates tumour growth in mice and is associated with colorectal and breast cancer, though she stops short of calling it causal.
Green Tea Kills Harmful Oral Bacteriainsight
Victoria notes that green tea is extremely effective at killing Fusobacterium nucleatum, and she gave a colleague a "big vat of green tea" as a gift after his test showed high levels.
Sugar in Tea Worse Than Biscuitsinsight
Victoria explains that sugar dissolved in hot tea causes more damage than eating a biscuit, and that sipping sugary tea over an hour keeps saliva acidic, leading to decay.
Wait Thirty Minutes Before Brushingstrategy
Brushing immediately after acidic or sugary foods grinds the acid into enamel. Instead, wait 30 minutes and chew sugar-free gum or a mint to neutralise saliva.
Never Rinse After Brushingstrategy
Rinsing with water after brushing removes the toothpaste from your teeth, which Victoria compares to showering off sunscreen before going into the sun. Spit only.
Most People Brush Far Too Brieflydata
The recommended brushing time is two minutes, but the average person manages only 20 to 30 seconds. Electric toothbrushes help because they time the session and include a pressure sensor.
Smoking Masks Gum Disease Symptomsinsight
Smoking constricts blood vessels in the mouth, so smokers often do not experience bleeding gums even when they have gum disease, making it harder to detect.
Dentistry and Medicine Fully Integratedinsight
Victoria envisions a future where a dentist's saliva test can flag heart or diabetes issues, and blood is no longer the only way to understand what is happening in the body.
Dr Victoria Sampson is a leading integrative dentist, researcher, and founder of The Health Society clinic in London. She is internationally recognised for her pioneering work on the oral microbiome and its links to systemic health. In today’s Moment, Dr Sampson reveals the link between oral bacteria and cancers, and how your daily habits - like when you brush your teeth or what you drink - can significantly influence your oral microbiome. She shares practical tips to protect your mouth and the domino effect that can have on your overall health.
