Did you know that good oral health could protect you from Alzheimer’s disease? That’s the conclusion of break-through scientific studies published in the last year. We provide patients with regular cleanings at Healthy Smiles Family Dental in Salem, but we hope our patients will come see us whenever they notice the signs of gingivitis. The bacteria that cause it could become a big problem. Porphyromonas gingivalis is a species of bacteria that causes gum disease. It excretes toxins called gingipains as a means of defending itself against white blood cells. These toxins are common, but are found in especially high levels in the brains and spinal fluid of people who suffered from Alzheimer’s disease. Testing on animals confirmed that the gingipains from oral bacteria that affects their species trigger the production of neural plaque. Another study found that P. gingivalis is able to travel from the mouth to the brain in humans. Scientists caution that gum disease is probably not the ...
