It is estimated that approximately fifty million individuals across the world are affected by dementia, and this number is projected to triple by 2050. Various factors contribute to the increase in dementia cases, and research has indicated a strong correlation between inadequate oral hygiene and the degeneration of brain functions that are emblematic of dementia. This write-up delves into the scientific association between oral health and dementia and guides how to maintain proper oral hygiene to decrease the likelihood of developing dementia.

Dementia is a collection of symptoms marked by cognitive decline, including loss of memory, reasoning, and thinking abilities. It should be noted that dementia is not a distinct ailment, but rather an encompassing term for these symptoms. While it is commonly believed that dementia is a natural part of the aging process, this is not the case. As one age, one's oral health can play a significant role in determining the likelihood of developing dementia. Experts assert that the link between oral health and dementia is more complex than one might imagine.

The Relationship Between Oral Health And Dementia

The connection between oral hygiene and dementia is significant.

When your oral hygiene is inadequate, there's a higher likelihood of harboring harmful oral bacteria. These bacteria can spread through the bloodstream and find their way to the brain, causing disruptions in nerve connections, damaging nerve cells, and even injuring brain tissue. Additionally, gum diseases can elevate inflammatory markers in the blood that have been known to harm brain cells. These mechanisms are widely researched and are considered significant factors linking oral health to dementia.

Individuals with varying dementia stages frequently experience difficulty in performing simple daily activities, such as brushing and flossing their teeth. As dementia progresses, they become reliant on others to look after their oral and general health. Some may even resist aid and have difficulty communicating, posing challenges in oral care. Unfortunately, this leads to the deterioration of teeth and gums due to the accumulation of plaque, which eventually results in gingivitis and tooth loss.

After learning about the scientific link between dementia and oral health, it's time to explore the findings of relevant studies.

Dementia And Oral Disease: Study


The correlation between oral health and dementia works both ways. Research reveals that inadequate oral health can result in a reduction in cognitive abilities and dementia, but individuals with dementia are also vulnerable to oral ailments. It is worth examining the figures.

Dementia And Gingivitis


Individuals afflicted with dementia tend to harbor an increased amount of plaque on the surfaces of their teeth. This demographic is susceptible to experiencing inflammation of the gums, gingivitis, and periodontitis. A study revealed that individuals with gum inflammation face more than twice the risk of developing dementia. A separate study confirmed that individuals displaying a high level of oral plaque face a fifteen-fold higher likelihood of experiencing significant cognitive deterioration as they age.

Dental Cavities And Dementia


Individuals who suffer from dementia and cognitive decline frequently receive prescriptions for medications that have the unintended consequence of diminishing saliva production. Insufficient saliva leads to a parched mouth and heightens the likelihood of tooth decay. Research has demonstrated that individuals who are diagnosed with dementia can experience numerous instances of tooth decay on their enamel surfaces within a single year.

Teeth Loss And Dementia


If you have at least 20 healthy teeth, your risk of developing dementia decreases significantly. However, losing even one tooth over 10 years can increase your risk of cognitive decline by 12%. Dementia can cause forgetfulness, such as forgetting to take out dentures at night, which can lead to an oral infection called stomatitis. Additionally, some people with dementia may forget to wear their dentures, which can accelerate the progression of the disease.

Learn How To Maintain Your Oral Health.


Dementia is caused by multiple factors, making complete prevention impossible. Nevertheless, preserving good oral hygiene is an effective way to delay cognitive decline. If you're seeking ways to combat dementia and oral issues, scheduling an appointment with your dentist is a great place to begin.

Be mindful of what you eat. Consuming a well-rounded diet that is abundant in fruits, veggies, and whole grains can aid in maintaining the health of your teeth and gums. Refrain from indulging in sugary or acidic foods and beverages, as they can lead to erosion of your teeth.

Make it a point to see your dentist on a regular basis. Consistent dental exams and cleanings are crucial in preserving optimal oral health. Your dentist can catch early indications of gum disease or tooth decay and administer treatment before they worsen. It is recommended to schedule appointments with your dentist at least twice a year.

It is advisable to utilize mouthwash for improving your oral hygiene. This solution can effectively eliminate the bacteria in your mouth and leave you with a minty fresh breath. Opt for a mouthwash containing fluoride to reinforce the enamel of your teeth.

To maintain a healthy mouth, make sure to brush your teeth twice a day. This is a simple yet highly effective method. Use a soft-bristled toothbrush and fluoride toothpaste to brush for two minutes each time. Remember to also brush your tongue to eliminate bacteria.

Ensure to floss daily. Flossing is equally crucial as brushing for maintaining good oral hygiene. It eliminates plaque and food debris from the areas between your teeth and below the gum line, which are unreachable by your toothbrush. It is recommended to floss at least once a day, preferably before going to bed.

Cease smoking. The habit can harm blood vessels and obstruct the blood flow to the brain, thereby increasing the likelihood of dementia. Additionally, it accelerates the risk of dementia, indirectly, by leading to gum diseases and oral cancer. Therefore, it's advisable to quit smoking to reduce your chances of developing dementia.

It is important to address any dental problems as soon as possible. Whether it be a cavity or gum disease, prompt treatment can prevent the issue from escalating.

If you have lost some of your teeth, it may be worth considering dental implants. These implants can assist with chewing food and keeping up nutrition levels. Moreover, they have the added benefit of keeping your remaining teeth in good health.

If you are caring for a person with dementia and they require assistance with their oral care, make sure to help them brush and floss. Additionally, if there is a history of dementia in your family and you are at risk, it is important to maintain regular oral hygiene practices. This includes visiting the dentist every 6 months to monitor your oral health.

The correlation between inadequate oral hygiene and dementia is convincing, and focusing on our dental well-being is a crucial approach to safeguarding our cognitive health as we grow older. Upholding good oral health can decrease the chances of developing dementia, and promote superior physical health for an extended period. Therefore, don't delay - begin to prioritize your oral health today!
