Gum Disease and Dementia: Are They Related?

Is there a link between Alzheimer's, dementia, and oral bacteria?

Over the past several years, we’ve seen research linking gum disease with both dementia and Alzheimer’s. In one study, almost every Alzheimer’s subject who had passed away showed evidence of periodontal (gum disease) bacteria inside of their brains. (1)

What Researchers Suspect

There are specific types of oral bacteria found in periodontal disease that are known to secrete specific toxins that are proven to destroy brain neurons. (2) We know this because researchers have exposed lab mice to this specific bacterial strain and observed neuron degeneration as a result.

Because of these studies, it’s important to consider that untreated, chronic periodontal disease could potentially place people at risk for a higher chance of developing dementia-related disorders.

What You Can Do at Home

Gum disease can easily be reversed when it’s diagnosed in the earliest stages of gingivitis. With good home care—including daily and proper flossing methods—oral bacteria can be removed before spreading into the bloodstream.

Chronic periodontal infections should be treated promptly before the infection spreads deeper and damages supporting tissues around your teeth. The earlier gum disease is addressed, the less bone loss there is. Thorough brushing along the gumlines, daily flossing—to remove bacteria between teeth and below the gum tissues—and regular professional cleanings are the most effective steps. Just keep in mind that tartar buildup and periodontal pockets need to be addressed by a dental professional, as it’s impossible to care for those areas at home.

Better Smiles, Better Brain Health

When you improve your oral health habits, you potentially reduce your risk for bacteria known for causing neuron damage in your brain. If your family has a history of dementia or an increased Alzheimer’s risk, talk to your dentist about a preventative oral health plan.
