Can Flossing Your Teeth Help Fight Against Cognitive Decline?

Strong oral hygiene can help us in many ways. One such part of effective oral hygiene is flossing each day. Recent research has suggested that tooth loss is linked to cognitive decline, which therefore shows the importance of adopting excellent oral hygiene, which appears to help battle against cognitive conditions like Dementia or Alzheimer’s Disease.

Flossing is an important part of oral hygiene. The simple action of passing a thin cord between our teeth can have huge benefits, with food and dental plaque being removed.

The intention is to clean those hard-to-reach areas in our mouth that a toothbrush can’t quite get to. Flossing regularly can help to prevent gum disease and the build up of plaque, which therefore improves our oral health [1].

Interestingly, poor oral hygiene has been linked to cognitive decline. This potential link has been researched heavily in the past, which has yielded inconsistent results [2].

However, a recent study suggests there is a certain link between poor oral hygiene and cognitive decline [3]. This study reinforces the importance of flossing as part of our day-to-day oral health routine, and suggests it can help to prevent cognitive decline.

The Study

The study in question was a meta-analysis conducted by researchers at The New York University’s Rory Meyers College of Nursing. The research analysed 14 pre-existing studies that investigated a link between tooth loss and cognitive decline.

After combining the 14 studies, there were 34,074 participants, with 4,689 cases of people with diminished cognitive function – such as having Dementia or Alzheimer’s Disease [3].

The results showed that adults with more tooth loss had a 1.48 times higher risk of cognitive impairment. Moreover, tooth loss was also linked to a 1.28 times higher risk of developing Dementia [3].

Furthermore, the more teeth that are missing – the higher the risk of cognitive impairment. These are very worrying statistics, and shows the importance of strong oral hygiene to protect against tooth loss and gum disease.

Another interesting finding that the study concluded was that for those that lose teeth, they were likelier to have cognitive decline if they didn’t have dentures. This was an unexpected finding, but shows how dentures can be very effective for our oral health.

What the results mean

Senior author Bei Wu – who is a Professor in Global Health at the college – said “Given the staggering number of people diagnosed with Alzheimer’s disease and dementia each year, and the opportunity to improve oral health across the life span, it’s important to gain a deeper understanding of the connection between poor oral health and cognitive decline” [3].

The authors of the study stated that limited access to dental care was a big problem and was contributing to this situation. An example of where this is also happening in Canada is the Sioux Lookout, where similar problems exist (click here to read more).

The authors attempted to look for consistencies to draw conclusions on what caused these results. They suggested that the problem of missing teeth can affect chewing, which has the potential to make a person’s diet unhealthier.

Moreover, tooth loss can also happen as a result of gum disease, which involves inflammation, and already has a pre-existing link to cognitive impairment [4]. Untreated gum disease also increases the risk of developing other health conditions [5].

The importance of oral hygiene

The findings of this study show us all how important strong oral hygiene is. While many people brush their teeth twice a day, not many floss as well. But this study shows that flossing should be an important part of our oral health routine.

Flossing should be an every-day part of our oral health routine. Importantly, this routine should extend to our wider diet – including trying to avoid sugary foods wherever possible, along with drinks with a high-sugar content and alcohol.

It is most crucial to attend regular dental check-ups, as these check-ups help us to detect problems early. The earlier that oral problems are detected, the easier they are to treat. Dental problems won’t go away, therefore they should be acted on as soon as possible.

What we offer our patients at Savanna Dental

At Savanna Dental, we are proud to offer our patients a vast array of services, whilst providing them with a convenient, caring and comfortable experience. Our dental clinic is based in an easy-to-reach part of Calgary, Alberta, Canada.

As we have mentioned, getting regular dental check-ups is important. When treatment is required following a check-up, then we will provide our patients with a treatment plan that is suited to their circumstances.

Among the services we provide at our Calgary dental clinic are regular cavity fillings, root canals, and dentures. The study mentioned earlier shows how useful dentures can be. Dental implants can be a useful alternative to dentures, if you want to avoid them. We also provide some cosmetic dentistry treatments, including teeth whitening.

We mentioned flossing earlier, and it is likely that some people will be new to the practice of flossing. We can give you advice on how is best to floss, or advice on any other dental issues you have.

Accessing dental care in Canada is renowned for being difficult, and this poor access, along with the high costs involved, puts many people off visiting the dentist. However, our Calgary dental clinic Savanna Dental follows the Alberta Dental Fee Guide, which means that we offer affordable and transparent care to our patients.

Summary

Cognitive decline largely appears inevitable, with cases of Dementia and Alzheimer’s Disease continuing to rise [6]. For many years, efforts have been made to try and find a way of addressing these rising numbers. It seems that good oral hygiene can make a difference, which underlines the importance of us all taking our oral health seriously.

Our Calgary dental clinic Savanna Dental offers our patients a wide range of services, as mentioned above. We hope that you consider coming to our clinic for your regular check-ups.
