One less tooth, aging One more year

Research has shown that for every tooth lost, the brain grows 1 year faster. Professor Satoshi Yamaguchi of the Graduate School of Dentistry at Tohoku University in Japan recently published this research in the international academic journal ‘Neurology’.

We were able to track the memory and dental health of 172 people without memory problems at the start of the study for four years. The age of the study subject was 67 years old. The condition of the other person's teeth, including the number of teeth, was checked every four years. At the same time, the size of the 'hippocampus' in the cerebrum, which is responsible for memory, was measured using magnetic resonance imaging (MRI).

As a result, the study subjects only progressed for one year, with the left hippocampus growing in size for each tooth studied. In the case of research subjects who experienced enough pain when chewing food, especially when they had more than one tooth, the crust was moved forward by 1 year and 4 months, so the lateral hippocampus had difficulty remembering chunky information. “As the number of teeth decreases, the stimulation for chewing food decreases, and blood flow decreases, which can affect the brain,” he said.
