This is the number of people the World Health Organization (WHO) estimates are affected by Alzheimer’s disease. They also warn that there are nearly 10 million new cases every year. (https://www.who.int/news-room/fact-sheets/detail/dementia)
In the U.S., the disease affects over 5 million adults, with one in three seniors dying from Alzheimer’s or another form of dementia. According to the Alzheimer’s Association, Alzheimer’s disease is the nation’s sixth leading cause of death. (https://www.alz.org/)
Research is actively pursing a way to not only predict the onset of Alzheimer’s disease, but prevent it. Of course, this requires finding its cause. Major studies are continually making headway in this pursuit. One of its possible ties has revealed itself in a way that may surprise you – Periodontal (gum) disease.
The oral bacteria of gum disease is getting more and more attention from researchers for its ability to create inflammatory reactions far beyond the mouth. Research has already found links between oral bacteria and heart disease, stroke, diabetes, arthritis, impotency, preterm babies and more. Now, the correlation between oral bacteria and Alzheimer’s disease and dementia adds to a long, concerning list.
Obviously, the bacteria in your mouth are far more destructive than the cause of bad breath and cavities. According to researchers, the infectious bacteria of gum disease has been linked to brain tissue degeneration. In one study, brain tissue samples from patients with and without dementia showed that a particular component of oral bacteria was found in 4 out of 10 Alzheimer’s disease tissue samples. This same bacterial component was not found in any of the brain tissue samples of people who did not have Alzheimer’s disease.
Researchers think these bacterial components found in the brain may trigger a response by the immune system that lead to pathological changes. Through this chain reaction, the study shows a pathways is created to Alzheimer’s. While the findings do not prove that oral bacteria causes Alzheimer’s disease, the links shown are sound reasons to maintain good oral health.
Because the bacteria of gum disease can weaken oral tissues, bacteria are able to enter the bloodstream and travel through the bloodstream to the brain. This can lead to degeneration in brain tissue that appears similar to Alzheimer’s disease.
This extensive research was conducted after a previous study on mice infected with specific periodontal bacteria. Researchers in this study found the bacteria traveled to the brain in mice, which prompted further studies involving humans.
Periodontal disease begins silently. It is not always obvious in early stages. However, as gum disease progresses, you may see blood when brushing and have frequent bad breath and sore and swollen gums. As it worsens, gum tissues turn from a healthy pink color to red.
Some level of periodontal disease exists in over 47 percent of the adult population. (https://www.perio.org/consumer/cdc-study.htm) Its early-stage, gingivitis, is one of the most common diseases found in humans and is more common than the common cold. According to the Centers for Disease Control & Prevention, nearly 64 percent of adults ages 65 and over have moderate or severe levels of periodontal disease.
Yet, preventing gum disease requires minimal time and expense. Twice daily brushing (at least two minutes each time) and flossing will help keep oral bacteria to a minimum between regular dental check-ups and cleanings. These visits remove any built-up If you are a smoker or take medications that are drying to oral tissues, hygiene visits every four months may be advised.
Alzheimer’s disease is a terrible way to spend one’s final years, and just as bad when we watch people we love as they suffer through years of decline. Keep the bacteria levels in your mouth under control and stay involved with regular dental visits to lower your risk.
Remember – gum disease only worsens without treatment. In addition to increasing susceptibility for serious diseases, it is the nation’s leading cause of adult tooth loss.
