From the youngest age we're told we ought to brush our teeth to avoid losing them as we age.
"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," YamaguchiA healthy PD range is between one and three millimeters; PD of three or four millimeters in multiple spots is classified as mild gum disease; and severe gum disease involves PD of five or six millimeters in several spots. Analysis was based on the average PD for each participant at baseline and four years later.
The researchers discovered that the number of teeth and the extent of gum disease were related to changes in the left hippocampus of the brain. The hippocampus experiences volume loss early in Alzheimer's disease progression. frameborder="0″ allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen>
The left hippocampus shrank more quickly in people with mild gum disease who alsi had fewer teeth. One less tooth increased the rate of brain shrinkage in people with mild gum disease by an amount that was nearly equal to an additional year of brain aging.teeth was linked to a faster rate of brain shrinkage in the same region. The increase in left hippocampus shrinkage caused by one more tooth was equivalent to 1.3 years of brain aging, in people with severe gum disease.
The study involved a small number of people, all from one region in Japan, making it important that studies should be undertaken on a larger, more diverse populations before these results can be generalized.
