Dental-Related Diseases Raise Dementia Risk

According to the results of a recent study, dental and periodontal diseases may increase the risk of developing dementia.

In fact, the risk of developing types of dementia such as Alzheimer’s disease and vascular dementia was found to increase by up to 1.18 times.

This study was conducted by a joint dental and medical research team from Seoul National University, Korea University, and others, based on data from about 2.55 million patients who underwent cardiovascular and dental checkups registered with the National Health Insurance.

It was found that dental conditions such as periodontal disease, dental caries, and tooth loss contribute to an increased risk of developing dementia. In particular, periodontal disease increased the risk of all-cause dementia by 1.07 times, Alzheimer’s by 1.09 times, and vascular dementia by 1.04 times.

The results also showed that dental caries and tooth loss increase the risk of dementia. When there were 15 or more missing teeth, all-cause dementia increased by 1.04 times, Alzheimer’s by 1.05 times, and vascular dementia by 1.18 times.

On the other hand, professional toothbrushing and brushing your teeth at least twice a day were found to significantly lower the risk of each type of dementia by about 10%.

The research team explained, "Periodontal disease, cavities, and tooth loss have an independent association with the risk of developing dementia, and having two or more dental conditions has a greater impact on the onset of dementia. Comprehensive oral hygiene management, such as professional toothbrushing, will help reduce the risk of dementia."

This highlights the importance of maintaining oral health and paying attention to dental care in order to maintain brain health. I recommend that everyone make sure to care for their teeth even if it feels bothersome, and I also recommend visiting the dentist regularly. Thank you.
