Key Points :
Japanese researchers have discovered that “gum disease” and “loss of teeth” are related to the shrinkage of “Hippocampus,” which is the memory brain. If teeth and gums are strong The teeth are complete and can chew normally. It will increase the flow of blood and oxygen to the brain. Makes the brain strong. Dr. Rodrigo Neva said that gingivitis and periodontal disease is a very silent disease. Patients are often unaware until they become severe and lose their teeth. Some research suggests that periodontal disease is linked to dementia, diabetes and heart disease.
In early July 2023, a report in the neuroscience journal Neurology described a study by Satoshi Yamaguchi, a researcher at Tohoku University in Japan, who discovered that “gum disease” and “loss of teeth” were the cause of the disease. ” is associated with the contraction of “Hippocampus,” which is the memory brain. And this type of contraction is often found in patients with Alzheimer’s disease.
Earlier in 2020, a similar report was released as well. This is the research of Dr. Angela Kamer from the College of Dentistry. New York University by demonstrating the relationship between An “unbalanced group of bacteria” found under the gums which is linked to some biological substances in ‘CSF’ that indicates Alzheimer’s disease in adults
These findings in both cases are telling “working people” at all age levels that “Dementia and Alzheimer’s disease” are no longer far away, but close enough to reach for a toothbrush every day.
How can oral health affect the “brain”?
Japanese researcher Satoshi Yamaguchi explains that this study shows that chronic inflammation in the gums and teeth is a common cause. may increase the risk of Dementia in the hippocampus or what science calls this reaction “Shrinking the brain” because it was found that the microorganisms that cause gingivitis are May invade brain cells and damage nerve tissue
Regarding the case of “dental decay and tooth loss,” Yamaguchi said Missing teeth can reduce the urge to chew. This has been shown to be linked to cerebral shrinkage in patients with missing teeth. while if the teeth and gums are strong The teeth are intact and perform normal chewing functions. It will increase the flow of blood and oxygen to the brain. Make your brain healthy
However, the researchers emphasized that This study did not prove a causal relationship between gum disease and brain shrinkage. But this study clearly indicates that Number of missing teeth and incidence of gingivitis Correlated with the rate of atrophy of the hippocampus. Most often found in the late working age group and the elderly group aged 55 years and over (results from the experiment in a relatively small sample of 172 people).
“We need to reconfirm the results of this study. By studying a larger and more diverse sample size. Intervention studies are also needed to confirm a causal relationship. and to explain the mechanism of such a link,” Yamaguchi said.
“Gum disease” is a “silent threat” and can get worse without realizing it!
despite these limitations But the study provides convincing evidence that Maintaining good oral hygiene can protect us from brain disease later on. However, gum disease is considered a “silent threat” and can progress without pain. As a result, many people overlook proper care of their gums and teeth.
Penn Dental Medicine’s president of periodontology, Rodrigo Neiva, told the New York Times that it was consistent with the above. Gingivitis and periodontitis are very silent diseases. Patients are often unaware until they lose their teeth.
According to the U.S. Centers for Disease Control and Prevention, nearly half of adults in the United States over the age of 30 show symptoms of “gum disease,” and 9 percent have severe gum disease, also known as gum disease. “Periodontitis” when left untreated Gum disease will be more difficult to cure. and some research suggests Periodontal disease has also been linked to dementia, diabetes and heart disease.
In addition, a 2021 international study of more than one million people found that People with poor dental health have a 21% chance of developing Alzheimer’s disease, including several studies confirming “Gingivitis” has been linked to the occurrence of “diabetes”, “heart disease”, as well as leading to chronic inflammation in various systems.
How to care for gums and teeth far from risk “Dementia”
It is important to take care of oral health at all ages. by starting simple By having the discipline to brush your teeth twice a day, there are also additional recommendations from the University of Rochester Medical Center:
1. Brushing and flossing at least twice a day can help prevent gingivitis, tooth decay and tooth loss.
2. Scaling and dental examination should be performed by a dentist at least once a year.
3. Brush your teeth properly by placing the toothbrush at a 45-degree angle to the gums and brushing each tooth 15 to 20 times. Gently move the brush up and down in short strokes. Do not scrub in a left-right direction.
4. Always use a soft brush and fluoride toothpaste.
5. Toothbrushes should be replaced every 3 or 4 months or following a cold, strep throat.
6. Don’t store your toothbrush in a closed container. because it stimulates the growth of microorganisms
7. Use dental floss carefully. Hold the floss firmly between your thumb and forefinger. Place the floss between the teeth and gently move the floss up and down.
8. When the floss reaches the gum line, wrap it around one tooth, gently rubbing the sides of the tooth, moving the floss up and down. (Level below the gum line). Repeat for all teeth. Be sure to floss the back teeth as well.
