Brush and floss!

In the Daily Wire, Amanda Prestigiacomo reports, Porphyromonas gingivalis, a key bacteria in chronic gum disease, appears to be the cause of Alzheimer's disease, researchers believe.

"Bacteria involved in gum disease and other illnesses have been found after death in the brains of people who had Alzheimer’s, but until now, it hasn't been clear whether these bacteria caused the disease or simply got in via brain damage caused by the condition," reports New Scientist.

The finding, says the site, could lead to a vaccine for Alzheimer’s: "[A] drug that blocks the main toxins of P. gingivalis is entering major clinical trials this year, and research published today shows it might stop and even reverse Alzheimer's."

...According to Colgate.com, signs of gum disease include, "gums that bleed when eating, brushing, and flossing because they are swollen and tender. You may also notice that your gums are receding. When this happens, your teeth look longer. If you notice sores in your mouth or pus in between your gums and teeth, then chances are you may have gum disease."
