A simple step-by-step study may reduce the risk of Alzheimer's, according to a recent medical report.
The study highlights the importance of cleaning teeth at least twice a day, indicating that this step will protect the person from many diseases.
Scientists have found bacteria responsible for periodontal disease and tooth decay in brain tissue, spinal fluid and Alzheimer's patients.
Experiments on mice show 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, reports Sun.
According to Dr. Stephen Domeni, a study of mice, is the first to link oral disease to Alzheimer's disease.
According to medical data and figures, about 45% of people worldwide suffer from periodontal disease.
Commenting on the study, the British Dental Society said: "The study confirms the importance of oral health as a key issue, not a secondary issue."
