This Unlikely Body Part Affects Your Brain Health

If you’re like most people, you want to be able to count on your brain for dependable memory and reasoning as you age. No one wants to get lost in the bleak land of dementia.

But while you can’t count your brain cells or neurons to see how many you’re hanging on to as the years pass, there’s another part of the body where you can see and count how much you’ve got left, and it does give an indication of how your brain is aging. Let me explain. . .

The part of the body where you can calculate your odds for better brain health is your mouth and the number of teeth that remain. Researchers have found that, in general, the health of your mouth and teeth exerts a significant influence on the wellness of your brain and thinking ability.

Dentition Takes a Bite out of Dementia

When scientists at the University of Kentucky College of Medicine and College of Dentistry examined the dental records of women who enrolled in what was called the “Nun Study,” they found that the more teeth the women retained into old age, the more likely they were to avoid Alzheimer’s disease.

The Nun Study was designed to analyze aging and Alzheimer’s disease among Catholic sisters of the School Sisters of Notre Dame who lived in Milwaukee. The scientists from Kentucky correlated the dental records of 144 women with the annual mental ability tests they completed. The women were 75 to 98 years old at the start of the study.1

“Of the participants who did not have dementia at the first examination,” the researchers wrote, “those with few teeth (zero to nine) had an increased risk of developing dementia during the study compared with those who had 10 or more teeth.”

Chewing Ability

Along with how many teeth you keep as you age, your ability to chew on hard foods like apples and raw carrots may also indicate the likelihood of maintaining your mental capabilities.

To investigate this relationship, researchers at the Karolinska Institutet in Sweden analyzed loss of teeth, chewing ability and cognitive function in a random sample of 557 Swedes who were 77 years old or older. They found that the people who had the most trouble chewing on hard food ran the highest risk of developing cognitive impairments as they aged.2

The Swedish researchers theorize that a lack of teeth (and chewing) may be connected to less blood flow to the brain, and the reduced blood flow may harm brain health. They also found that people with dentures who could still chew well did not suffer as many brain problems.

Gum Problems

While you’re busy holding on to your teeth, don’t forget to brush, floss and maintain the health of your gums. A 20 year study in Denmark of people who were 50 years old at the start of the research found that those with inflamed gums and gum disease were nine times more likely to have cognitive problems by age 70.3 Gum disease is a clear, shocking risk factor.

“The research suggests that cognitively normal subjects with periodontal inflammation are at an increased risk of lower cognitive function compared to cognitively normal subjects with little or no periodontal inflammation,” says researcher Angela Kamer.

Unhealthy teeth and diseased gums have not only been linked to Alzheimer’s and dementia. They’ve also been linked to heart disease, cancer, arthritis and more. Did you know that the presence of root canals can put you at much higher risk of cancer? And that you can have this bad dental work fixed if you go to the right type of dentist? If not, then I urge you to order our Special Report The Secret Poison in Your Mouth. It’s a complete guide to WHY dental problems are so dangerous and how to get them fixed. Mainstream dentists won’t do it for you. It’s necessary to seek help from a biological dentist or an “alternative” dentist, if you will. Click here to learn more about this report.
