THIS dental habit is directly linked to Alzheimer's and dementia

Oral Health and Brain Health

The video argues that oral health may be connected to brain health. It says the gum-disease bacterium Porphyromonas gingivalis has been found in brain tissue from people who died with Alzheimer’s disease. It suggests that inflamed or bleeding gums could allow oral bacteria to enter the bloodstream.

The video links these bacteria and inflammation with brain changes, but its subtitles do not name specific studies or establish that gum disease directly causes dementia.

Practical Steps Highlighted

• Brush your teeth twice a day.
• Floss regularly and use suitable toothpaste.
• Don’t ignore bleeding gums or other signs of gum problems; arrange a dental check-up.
• Keep up with dental visits, including for older family members.
