If you are trying to reduce your chance of developing Alzheimer’s disease, you may want to plan an appointment with your dentist. New research shows that gum disease should be included in the list of factors that can increase the likelihood of Alzheimer’s disease development. Some new studies have been integrated into earlier research that links the changes in the oral environment with a higher risk of dementia. In addition, new research suggests that after a Mediterranean diet can improve your oral health.
Mediterranean diet and gum disease:
The periodontal disease has been linked to heart attacks and strokes. A study of about 200 Britons reports that those who follow a balanced diet with the Mediterranean diet are less likely to have gum disease and systemic inflammation (Periodontics newspaperSeptember 15th 2025). More than half of the participants, 112 of them, reported close adhesion to a Mediterranean diet. The rest of the volunteers were more likely to have a serious gum disease, as their diet deviates from a Mediterranean standard. Eating very red meat, in particular, was associated with high levels of difficulty and inflammatory markers in the blood. Continue to read to find out about possible consequences.
Oral health associated with a lower risk of dementia:
British researchers report that oral health appears to be associated with a lower risk of dementia (Pnas nexusJanuary 2025). They analyzed the bacteria that live in the mouths of 115 older people. 55 of the participants experience mild cognitive impairment or MCI. Those with more Nose The bacteria in their mouths had better visual attention and executive function than the MCI. These bacteria were also associated with better work memory between volunteers without cognitive difficulties.
If Purple The bacteria were present, people were much more likely to have cognitive difficulties. According to scientists, diet has a strong impact on oral microbicide. Nitrate -containing vegetables, such as the DASH diet or a Mediterranean diet, appear to encourage bacteria associated with the best cognitive function.
Oral germi associated with the risk of stroke:
A Japanese study recently presented at International Congress Strengthened the amazing relationship between the composition of the oral and intestinal germ and the risk of stroke. Scientists had previously discovered a link between the presence of Streptococcus Mutans in the mouth and the risk of bleeding in the brain. These bacteria are responsible for the decomposition of teeth, but they are not the only ones.
According to researchers, the presence of Streptococcus AnginosusAnother type of bacteria, either in the saliva or the intestine, was associated with a 20% higher risk of stroke. Two different bacteria, Anaerostipes Hadrus and Bacteroides plebeiuswere associated with lower stroke risk.
Two years of follow -up revealed that stroke survivors who hosted S. Anginosus were at a significantly higher risk for significant cardiovascular events or death after. This study included 189 people who had strokes and 55 who did not. Scientists are hoping to expand the study to appear in the future with the potential risk of oral dysfunction in the stroke.
Time for thread to avoid gum disease:
Another study suggests that the thread may be good for your brain (Meeting: AHA 2025 International Conference). The researchers analyzed data from 6200 elderly people who participated in the risk of atherosclerosis in the study of communities (ARIC). About 65% of volunteers had the habit of being made on a regular basis.
During the 25 years of follow -up, just more than 400 participants had a stroke. The usual flossers were 22% less likely to have ischemic stroke and 44% less likely to have a cardiovascular stroke. They were also less likely to have developed vaginal fibrillation. Even people who were only once a week got some protection, but the more often people rushed, the less likely they were to have a stroke. Since strokes can often contribute to dementia, reducing the risk of stroke increases the likelihood of avoiding it.
What is the link between gum disease and Alzheimer’s disease?
In previous research, scientists compared brain samples from autopsies of people with Alzheimer’s disease and people of similar ages without brain condition (Presentation at the Annual Experimental Biology Meeting, 4/7/19). Found distinctive DNA indicating the presence of Gingivalis porphyromonasBacteria responsible for periodontitis, most often in brains affected by Alzheimer’s. P. Gingivalis It produces bacterial toxins known as scars that also existed in these brains.

Following P. Gingivalis and the brain:
The researchers conducted experiments in mice. They showed that P. Gingivalis It moves easily from the mouth to the brain. However, it can stop if the scars blocked. A drug company is already testing a drug that prevents Ulou, hoping that it will prove useful against Alzheimer’s disease.
Most of Alzheimer’s disease research has focused on the accumulation of plaques consisting of beta-amyloid proteins and taunts tau. When they accumulate in the brain, it is believed to damage the nerve cells and disrupt the neuron connections necessary for thought and memory. Some people carry a specific variant of a gene-arose-E4-that can increase the risk of developing such plates and tangles.
Other chronic diseases associated with periodontal disease:
Alzheimer’s disease is not the only serious problem associated with periodontal infection. Gum disease has previously been associated with type 2 diabetes, osteoporosis, rheumatoid arthritis and a series of cardiovascular complications. Researchers have even found links with certain types of cancer. In addition, people with poor oral health seem to have tougher time to control their high blood pressure (HypertensionOctober 22, 2018). The researchers examined data from the US National Health and Inquiry Research (NHANES). In the process, they found that about half of the participants had gum disease. The worse the periodontal disease, the more difficult it was to manage high blood pressure.
While beta-amyloid has been treated as the first culprit behind Alzheimer’s disease, some scientists assume that it may be part of the brain’s attempt to protect it from infection.

Among those receiving medical blood pressure, gum disease increased systolic measurement by 2 to 3 mm Hg. (Millions of mercury is the typical measure of blood pressure.) In addition, the treatment of periodontal disease has reduced the possibility of antihypertensive treatment.
Do not count on the oral solution against gum disease:
Periodontal treatment may need to overcome and rinse. Back in 2010, the FDA warned manufacturers in the mouth not to claim that their products could prevent or cure gum disease. The manufacturers of Listerine Total Care Actorywash; Cvs full care altourwash and Walgreen mouth rinse full action They were punished for advertising that their products can remove the plate or prevent periodontal disease. In summary, the FDA says consumers can use these products to reduce the likelihood of cavity growth, but there are no reliable data to suggest that they will protect the gums.
What can you keep your mouth healthy?
The key elements for preventing gum disease are simple: brush and thread at least twice a day. In addition, see a dentist for a thorough cleaning at least twice a year. In addition, your dentist (or periodontist, if you have one) will recommend tools such as soft hair options or water options for use between teeth. Providing gums with gentle stimulation can improve circulation and help them fight the infection. Sometimes periodontal infections require antibiotic treatment. On the other hand, conscientious oral hygiene can proceed a lot in the direction of maintaining gum people.
