Poor Dental Health And Brain Shrinkage

The Link Between Poor Dental Health And Brain Shrinkage


A ground breaking study recently published in the journal ‘Nature Aging’ which has shed light on a potential connection between poor dental health and brain shrinkage, specifically in the hippocampus, a critical region responsible for memory and learning. Led by researchers at Tohoku University in Japan, the study examined data from over 1,700 individuals aged 65 years and older, revealing a correlation between individuals with compromised dental health, such as gum disease or tooth loss. Also a smaller hippocampus compared to those with good dental health.

Understanding the Association

While the precise mechanisms underlying the association between poor dental health and brain shrinkage are yet to be fully understood, researchers hypothesize that inflammation may play a significant role. Inflammation is a natural response to infection and its chronic presence can inflict damage on brain tissue over time, potentially contributing to brain shrinkage.

Tips for Maintaining Good Oral Health

  • Regular Brushing: Brush your teeth thoroughly twice a day, dedicating at least two minutes to each brushing session. Use a fluoride toothpaste and a soft-bristled toothbrush to ensure effective cleaning.
  • Daily Flossing: Flossing once a day helps remove plaque and food particles from between the teeth and along the gumline, promoting gum health and preventing tooth decay.
  • Professional Checkups: Schedule regular dental checkups and cleanings with your dentist. These visits allow for the early detection of potential dental issues and the removal of plaque and tartar buildup.
  • Healthy Diet: Adopt a nutritious diet rich in fruits, vegetables and whole grains. These foods provide essential vitamins and minerals that support oral health.
  • Limit Sugary Drinks and Processed Foods: Reduce your consumption of sugary drinks and processed foods, as they can contribute to tooth decay and gum disease.

By adhering to these oral hygiene practices, you not only contribute to the well-being of your teeth and gums but also potentially safeguard your brain health.


The overall findings in the studies that link poor dental health to brain shrinkage highlight the significance of maintaining good oral hygiene practices for overall well-being. The potential association between compromised dental health and a smaller hippocampus emphasizes the potential impact on cognitive function and brain health.
