Doctor Reveals Simple Two-Minute Routine to Lower Dementia Risk

A recent podcast episode has brought attention to a simple two-minute routine that may help reduce the risk of dementia. Dr Amir Khan, a well-known medical practitioner and regular contributor on ITV, discussed this daily bathroom practice during his show, *No Appointment Necessary*. His insights suggest that flossing can significantly impact not just oral health, but also cognitive function.

In a conversation with co-presenter Cherry Healey, Dr Khan explained the connection between oral hygiene and dementia risk. He stated, “It’s true. It doesn’t prevent it, it reduces the risk. It’s incredible.” He emphasized that poor oral health can lead to gum disease, allowing harmful bacteria to enter the bloodstream and potentially reach the brain. This process can trigger an immune response, leading to chronic inflammation, which may be linked to cognitive decline.

Research supports Dr Khan’s claims. A study published in *PNAS Nexus* earlier this year indicated that maintaining proper dental hygiene through practices like brushing and flossing can influence brain function. Scientists from the University of Exeter, in collaboration with other researchers, examined the oral bacteria of 120 elderly individuals. Half of the participants had been diagnosed with mild cognitive impairment (MCI), a condition that can precede dementia, while the other half consisted of healthy individuals of similar ages.

The study found distinct patterns in the bacterial communities present in the participants’ mouths. According to *Study Finds*, two types of bacteria, Neisseria and Haemophilus, were linked to better performance in memory and cognitive tests. Conversely, the presence of certain bacteria, particularly Prevotella, correlated with lower cognitive assessment scores.

Dr Khan’s guidance is reinforced by additional research. A separate study published in the *Journal of Alzheimer’s Disease* in 2020 found that older adults exhibiting signs of gum disease and oral infections at the beginning of the study were more likely to develop Alzheimer’s over time.

To help maintain oral and dental health, the Health Service Executive (HSE) recommends scheduling regular check-ups with a dentist if any issues arise.

Dr Amir Khan’s insights highlight the importance of daily dental care, not only for preventing dental diseases but also for potentially lowering the risk of cognitive decline. As research continues to unravel the connection between oral health and brain function, simple habits like flossing may play a significant role in promoting overall health.
