Can Using Colloidal Silver Help You Prevent Dementia?

Hi, Steve Barwick, for

In a recent study, researchers from the University of California followed nearly 5,500 elderly people over a period of 18 years.

They found that those who brushed their teeth less than once per day were 65% more likely to develop dementia than those who brushed more frequently.

How could brushing your teeth more frequently result in lower risk of dementia?

According to Annlia Paganini-Hill, who led the study, which was published in the Journal of the American Geriatrics Society:

“Some studies have also found that people with Alzheimer's disease, the most common form of dementia, have more gum disease-related bacteria in their brains than a person without Alzheimer's.”

In other words, according to Paganini-Hill, when proper oral health care is not followed, bacteria known to cause gum disease can migrate into the brain, “causing inflammation and brain damage.”

Other Studies…

Have there been other studies demonstrating a link between poor oral health and the onset of dementia?

Indeed, there have.

For example, in a study titled, “Tooth Loss, Dementia and Neuropathology in the Nun Study,” published in the Journal of the American Dental Association, it was discovered by researchers that the more teeth a person loses to periodontal disease during aging, the greater the incidence of dementia. 

According to an article in Prevention magazine:

Experts think oral bacteria may spread to the brain through cranial nerves that connect to the jaw or through the bloodstream, and may contribute to the type of plaque that’s been linked to Alzheimer’s.

And according to an article on

“A growing body of research finds that bacteria and inflammation in your mouth are also associated with other problems, including heart attack and dementia, and may well jeopardize your overall health.”

What’s more, an article on tells a similar tale:

“Dementia and mental confusion has also been linked to poor oral hygiene.  A recent study showed that people who had cases of gingivitis or periodontal disease tended to exhibit sings of early Alzheimer’s, dementia or extreme mental confusion. 

Health care experts believe this is because the bacteria that forms in the mouth and causes many of the dental problems can easily enter the bloodstream, travel up to the brain and cause infections o inflammation.”

Finally, according an article by Elizabeth Kaye, MPH, PhD, professor and director of the epidemiology division in the Department of Health Policy & Health Services Research at Boston University Henry M. Goldman School of Dental Medicine:

“Within the past several years, an increasing number of studies have reported associations between oral health status and measures of impaired cognition in community-dwelling older adults.”

How Can Colloidal Silver Help?

Researchers already know that inflammation triggered by oral bacteria (also known as plaque bacteria) is implicated in a number of other serious conditions, including heart disease, stroke and diabetes.” 

In Angela Kaelin’s great article, Colloidal Silver, Oral Health and Heart Health, you’ll learn how good oral health habits – including regular oral colloidal silver usage to keep populations of problematic oral pathogens at bay -- can lower your risk for heart-related ailments.

And in one of my older articles, Colloidal Silver Tames the Dental Plaque Monster, you’ll learn that colloidal silver is a proven effective method for preventing the buildup of bacterial plaque.

Indeed, you’ll learn about a patent for a new dental procedure for stopping tooth and gum disease that depends exclusively upon the release of silver ions.  The patent states, in part:

“Administration of metal ions, preferably silver ions, to the site where microorganisms that cause gum disease reside…can destroy bacterial plaque on teeth and bacterial pockets under the gum line!”

In other words, bacterial plaque on the teeth and under the gum lines are extremely susceptible to the infection-fighting qualities of silver ions.

What’s more, according to a 1999 study conducted at Brigham Young University, the bacterium Streptococcus mutans, which is a major cause of dental plaque and tooth decay, was inhibited and destroyed using just 5 ppm of colloidal silver.

In fact, in the study colloidal silver was demonstrated to be as good at destroying the bacteria as five different classes of antibiotics, including: the tetracyclines, fluorinated quinolones (Ofloxacin), thepenicillins, the cephalosporins (Cefaperazone) and the macrolides (Erythromycin).

Finally, according to an article in, antimicrobial silver is also effective against yeast and fungal oral pathogens:

“A new study published in the Society for Applied Microbiology journal Letters in Applied Microbiology reveals that silver is fully capable of killing yeast-based mouth infections caused by Candida albicans and Candida glabrata.

Professor Mariana Henriques and her colleagues from the University of Minho in Portugal evaluated the effects of a silver nanoparticle solution on oral thrush, dental stomatitis, and various other mouth infections caused by the two aforementioned strains of yeast.

They came to the conclusion that, in all cases, the silver solution was effective at combating these infection-causing yeast strains, even when the size of the silver particles used varied dramatically.”

Little Doubt…

So there’s little doubt that regular and judicious use of colloidal silver as part of a good oral health care program can help prevent the overgrowth of oral bacteria that are known to cause tooth and gum disease, and are now implicated in damage to both the heart and the brain!

In my recent article, Colloidal Silver and Healthy Teeth and Gums, I discuss several ways colloidal silver can be used to keep oral bacteria at bay.

If you have not yet read that article, now might be a good time. 

And if you’ve already read it, now might be a good time to review it, considering the most recent information on the ability of oral bacteria to trigger the onset of dementia in people who do not practice good daily oral health care. 

But to summarize the article, I found that regular daily use of colloidal silver in my personal oral health care regimen over the course of five years produced a dramatic difference in the health of my teeth and gums. 

Indeed, for the first time in my life there have been no cavities, no plaque and no bleeding gums whatsoever, for five straight years, whereas in years past these signs of poor oral health were common to me.   

And what did I do differently?

First of all, I increased my teeth brushing schedule from once per day to three times a day.

Secondly, I began saturating toothbrush in colloidal silver before brushing, even spraying it directly onto the toothpaste. 

Third, after particularly heavy meals, I even add a bit of colloidal silver gel right on top of my toothpaste before brushing. 

After brushing, I spray colloidal silver onto my little “floss pic” and use it to poke out any food particles from between my teeth so that bacteria can’t use them as food. And I use the same “floss pic” with colloidal silver to scrape away any plaque between my teeth.

Afterwards, I also rinse my mouth with a mouthful of colloidal silver, swishing it around forcefully between the teeth and gums, and then spit it out. 

Finally, I rinse my toothbrush with warm water after each brushing, and then spray it lightly with colloidal silver before placing it in the toothbrush holder, in order to keep germs from growing on it while it’s not in use.

Not a Panacea

Of course, some researchers are quick to point out that while neglecting to brush your teeth might be “a sign of early vulnerability to dementia,” other factors can play a role, too, including poor nutrition, head injury and even infections by other types of pathogens not related to oral pathogens.

As these researchers point out, good oral health care is not a 100% guarantee against dementia. 

I agree.  And I’d hasten to add that we can’t go through life being afraid of everything. 

Nevertheless, practicing the principles of good oral health each day – including the use of colloidal silver during oral health care -- seems to be a simple way to help mitigate at least one potential avenue for dementia onset, i.e., the oral route.
