Routine Toothbrushing Could Postpone Alzheimer’s Disease

  • Researchers in Norway have discovered a clear connection between gum disease and Alzheimer´s disease.
  • DNA-based evidence shows that the bacteria causing gingivitis can move from the mouth to the brain.

Researchers at the University of Bergen in Norway has discovered clear evidence that Porphyromonas gingivalis (P.gingivalis), the bacteria that causes gingivitis or gum disease, can move from the mouth to the brain. When it does, it produces a protein that destroys the nerve cells in the brain, which leads to loss of memory and ultimately, Alzheimer’s.

P.gingivalis causes chronic infection in the gums. This type of bacteria is also linked to esophageal cancer, rheumatism and chronic obstructive pulmonary disease (COPD).

Clean your teeth properly for good memory

According to researcher Piotr Mydel, P.gingivalis does not cause Alzheimer’s alone, but the presence of these bacteria increases the risk of developing the disease and are also linked to a more rapid progression of the disease.

To slow down Alzheimer’s, “brush your teeth and use floss.”

Mydel also recommends regular dental visits and proper oral hygiene if you have gingivitis and have Alzheimer’s in your family.

New medicine can block harmful enzymes

Mydel also says that they have “managed to develop a drug that blocks the harmful enzymes from the bacteria, postponing the development of Alzheimer´s. We are planning to test this drug later this year.”
