The link between gum disease and dementia

A key bacteria that causes gum disease – Porphyromonas gingivalis –  may also be the root cause of Alzheimer’s disease, a form of dementia.

According to a study by King's College London and the University of Southampton,  brushing your teeth regularly could slow down the progression of Alzheimer’s disease.  Scientists discovered gum disease speeds up mental decline by six times.
