Poor dental health linked to decline in brain volume

Taking good care of your teeth may be linked to better brain health, according to a study published in the July 5, 2023, online issue of Neurology, the medical journal of the American Academy of Neurology. The study found that gum disease and tooth loss were linked to brain shrinkage in the hippocampus, which plays a role in memory and Alzheimer’s disease. The study does not prove that gum disease or tooth loss causes Alzheimer’s disease; it only shows an association.

Dr Satoshi Yamaguchi, a scientist at Tohoku University in Sendai, Japan and study author, said, “Tooth loss and gum disease, which is inflammation of the tissue around the teeth that can cause shrinkage of the gums and loosening of the teeth, are very common, so evaluating a potential link with dementia is incredibly important. Our study found that these conditions may play a role in the health of the brain area that controls thinking and memory, giving people another reason to take better care of their teeth.”

The study involved 172 people with an average age of 67 who did not have memory problems at the beginning of the study.
