Is There a Possible Link Between Dementia and Your Oral Health?

While it may appear that the simple act of brushing and flossing your teeth is primarily aimed at maintaining fresh breath and a bright smile, it plays a smaller role in a much larger health equation. Surprisingly, your oral hygiene is intricately connected to various potential health issues, including diabetes and heart disease. The primary culprit is inadequate oral hygiene, leading to the accumulation of plaque, which can result in conditions like gingivitis and periodontitis. Both of these conditions foster the growth of harmful bacteria and trigger an inflammatory response that can potentially enter your body through the bloodstream and inhalation.

Recent studies have uncovered associations between oral hygiene and dementia. In a nutshell, there exists a relationship between your dental health and the atrophy of the hippocampus, which is the shrinking of the brain’s hippocampal region. This atrophy is considered an indicator of Alzheimer’s disease (Mercola, 2023). So, what are the specifics of the connection and how can you work to improve your oral health to prevent furthering health complications?

The Connection Between Alzheimer’s & Dental Health

An unhealthy mouth is a linear process that we can work to prevent and reverse before it escalates to other serious conditions. A consistent lack of proper oral hygiene over a period of time leads to the development of gingivitis, an inflammatory disease caused by the buildup of unhealthy bacteria and plaque leading to bleeding gums and potentially escalating into periodontitis – and infection resulting in tooth loss. (Mercola, 2023). Periodontitis, commonly known as gum disease is the culprit of potential cognitive decline leading to Alzhemiers.

Together, this means the bacteria in your mouth from gum disease and associated tooth loss has potential to access your brain cavity through infected areas of the mouth. Additionally, individuals suffering from the impact of Alzthemiers might see a decline in self-care including oral hygiene leading to faster development of the disease and its symptoms (Mercola, 2023).

Protecting Yourself from Gum Disease

We know the connection of oral health to Alzhemiers primarily stems from periodontitis, known as gum disease, so how can we prevent it?

Start Early. Caring for your health isn’t limited to older adults; it is particularly impactful for individuals in their middle and young adult years. Since gum disease stems from a consistent lack of oral hygiene, establishing good practices at an early age can serve as a proactive measure to prevent it before it even begins.

Daily Practices. Implementing good daily practices into your routine is the first step in creating well-rounded oral hygiene. Start slow and begin by brushing twice a day and incorporate regular flossing and tongue scraping. These three things combined flush your mouth of harmful bacteria, prevent plaque buildup, and improve gum health.

Lifestyle. In line with other health advice, maintaining a healthy lifestyle proves highly effective in preventing diseases such as diabetes, heart disease, and Alzheimer’s. Try to minimize smoking, alcohol and sugary foods while striving to incorporate whole foods into your diet.

Oil Pulling. An additional precaution to consider adding to your hygiene regimen is oil pulling using coconut oil, known for its antibacterial properties that help reduce the bacteria in your mouth.

Importance of Brain Health

In addition to keeping your oral hygiene routine up to par, improving your lifestyle to incorporate brain healthy habits can work against a multitude of other health conditions.

Mental Health. A healthy brain is a healthy you. Proper self-care is shown in all sorts of  ways including taking good care of your mental health. Take the steps to improve your mental health through physical activity, mental stimulation like reading or crosswords, stress management, and social interaction.

Balanced Diet. Just like taking care of your oral hygiene incorporates a healthy diet, your brain health thrives on good nutrition and limited harmful substances like tobacco and alcohol. Also, don’t forget to hydrate!

Brain-Healthy Vitamins. Research has shown certain vitamins to be exceptionally effective for maintaining brain health. B-Vitamins like B12 and B6 were linked to slowing the rate of brain atrophy (Mercola, 2023). Additionally, Vitamin D and Magnesium are also shown to support healthy cognitive function. Please remember to consult with a healthcare professional before adding supplements to your routine.

All in all, the link between oral health and overall well-being is more significant than we might initially realize. The seemingly simple act of maintaining good oral hygiene through brushing, flossing, and regular dental care is not just about fresh breath and a bright smile; it’s a crucial part of a broader health equation. In addition to care at home, regular dental cleanings and checkups can help you stay on top of any emerging conditions.
