Recently, I attended Dr. Andrew Greenland’s webinar titled “What is the Bredesen Protocol?” —a fascinating deep dive into holistic approaches to brain health. One topic that particularly caught my attention was the emerging scientific link between Alzheimer’s disease and oral hygiene. As someone passionate about understanding how lifestyle choices impact chronic diseases, I was intrigued by the discussion on how oral bacteria could influence brain health. This prompted me to dig deeper into the connection between Alzheimer’s, oral bacteria, plaque, and calculus, uncovering compelling evidence that underscores the importance of maintaining impeccable oral hygiene (1).

The Surprising Role of Oral Bacteria in Alzheimer’s Disease

Research has increasingly pointed to a strong association between oral bacteria and Alzheimer’s disease. A recent study highlighted that bacteria responsible for gum disease are linked to the development of dementia, including Alzheimer’s (2)

These harmful microorganisms can enter the bloodstream through inflamed gums, traveling to the brain and triggering inflammatory responses. Once in the brain, they may contribute to the buildup of amyloid-beta plaques; a hallmark characteristic of Alzheimer’s disease (5).

For instance, pre-clinical studies suggest that specific strains of oral bacteria play a role in the pathogenesis of Alzheimer’s (3).

While clinical findings vary, there’s growing consensus among scientists that poor oral health creates an environment where “bad” bacteria thrive, increasing the risk of neurodegenerative conditions (10).

The Importance of Oral Hygiene in Preventing Alzheimer’s

Maintaining good oral hygiene isn’t just about preserving your smile—it’s a critical step in safeguarding your brain health. By controlling the population of harmful oral bacteria, you reduce the likelihood of them entering your bloodstream and reaching your brain. Regular removal of plaque and calculus prevents the accumulation of toxins that fuel inflammation throughout the body (6).

Dentists recommend brushing twice daily with fluoride toothpaste, flossing at least once a day, and scheduling professional cleanings every six months. These practices help keep oral bacteria in check, minimizing their potential impact on brain health. Additionally, adopting a diet low in sugar and rich in antioxidants supports both oral and cognitive wellness (2).

Practical Tips for Better Oral Health

If you’re looking to protect yourself against Alzheimer’s by improving your oral hygiene, here are some actionable tips:

1. Brush Properly: Use a soft-bristled toothbrush and brush for two minutes, covering all surfaces of your teeth.
2. Floss Daily: Don’t skip flossing—it removes food particles and plaque trapped between teeth that your toothbrush can’t reach.
3. Use Mouthwash: An antibacterial mouthwash can help kill germs and reduce plaque buildup.
4. Stay Hydrated: Drinking water promotes saliva production, which naturally washes away bacteria.
5. Visit Your Dentist: Regular dental visits allow professionals to detect early signs of gum disease and remove stubborn calculus (4).

Conclusion: Protect Your Brain by Caring for Your Mouth

The link between Alzheimer’s disease and oral bacteria is undeniable, highlighting the profound impact of oral hygiene on overall health. From plaque and calculus buildup to the proliferation of harmful microbes, neglecting your teeth and gums can have far-reaching consequences. Fortunately, taking simple yet effective steps to maintain oral health can significantly lower your risk of developing Alzheimer’s.

As I reflect on Dr. Andrew Greenland’s webinar, I’m reminded of how interconnected our bodies truly are. By prioritizing oral hygiene today, we invest in a healthier tomorrow, not just for our smiles, but for our minds as well.
