It's something strange indeed; scientists have recently found that dental bacteria may play a role in some cases of Alzheimer's! Bacteria linked to gum disease traveled to the brains of people Alzheimer's disease, suggesting that dental hygiene plays a role in the development of the memory robbing illness, some British researchers said.
An analysis of the brains of twenty dead people, 10 of whom had Alzheimer's, by researchers at University of Central Lancashire revealed the presence of bug P. gingivalis. The researchers suggested that the presence of the microbe triggers a chemical immune response that kills off brain cells. Bacteria in the mouth could hop into the bloodstream and travel to the brain after losing a tooth. Chewing, brushing and flossing are also able to transfer oral bacteria into the bloodstream, the study's lead scientist, StJohn Crean of the University of Central Lancashire, said that people should keep brushing and flossing. Keeping your mouth clean reduces the number of bacteria in it and the likelihood that they'll travel elsewhere. On the other hand, some experts including Dr Simon Ridley of the charity Alzheimer's Research UK, suggest that the poor oral health could be as a result of Alzheimer's rather than its cause. However, there is still plenty more to be understood about this topic
