The new study included 172 people. Their average age was 67 years. There were no memory problems at the start of the study.
As a result, the team of scientists found that in humans, the number of teeth and gum disease are associated with changes in the left hippocampus of the brain. Those suffering from mild gum disease experienced a faster reduction in brain volume in the left hippocampus. In participants with severe gum disease, more teeth were associated with faster brain shrinkage in the same area.
Experts have also found that in people with mild gum disease, faster brain shrinkage due to the loss of a single tooth is equivalent to almost 1 year of brain aging. For those suffering from severe gum disease, the reduction in brain volume was equivalent to 1.3 years of aging.
