NEW YORK (Reuters Health) – Daily cleaning of teeth can reduce the risk of developing Alzheimer's disease, according to a recent study.
The study emphasized the importance of cleaning teeth at least twice a day, stressing that this step would protect humans from many diseases.
Scientists have discovered bacteria that cause gum disease and tooth decay in brain tissue, cerebrospinal fluid and Alzheimer's disease.
Experiments on mice have shown that bacteria spread from the mouth to the brain, where the cells of this vital organ are destroyed.
Scientists at Cortexyme Pharmaceuticals in San Francisco later this year will apply the experiment to humans, the Sun newspaper reported.
According to Dr. Stephen Domeni, the mouse study was the first to link an oral disease to Alzheimer's disease.
According to medical statistics and figures, about 45% of the world's population suffers from periodontal disease.
Commenting on the study, the British Dental Society said: "The study confirms the importance of oral health as a fundamental issue and not as a secondary."
