Japanese scientists have come forward with the results of a study linking tooth loss with dementia in the elderly.
In a study done on 4,200 individuals, those who reported symptoms of memory loss were the ones who also had fewer of their own teeth. Dr. Nozomi Okamoto, the chief investigator of the study, has a couple of theories about this link. He says that the death of sensory receptors int he mouth can be linked with dying neurons in the brain, and that inflammatory substances released from infected gums can contribute to inflammation in the brain.
Food for thought, indeed.
