Researchers have concluded that the way our immune system “learns” from previous threats may actually have a negative impact on areas like inflammation. The researchers used gum disease to investigate their theory. They found that the inflammation caused by gum disease ends up having a negative effect on physical health, and can actually worsen future inflammation-based conditions.

Our immune system is a remarkable thing. It fights diseases, protects us from viruses and can detect any issues that may compromise our safety and overall health.

The various battles that the immune system encounters results in it developing a “memory” of sorts to protect us in the future from similar threats.

This is mostly great for our overall health. But this also has the negative impact of the immune system sometimes responding to something that it determines to be a threat – even if it isn’t.

For example, when the immune system is challenged by an internal driver like chronic inflammation, it can result in a misguided immune system response.

Researchers have looked into the overall process of inflammation, with a specific focus on gum disease. Therefore, this research is very important for oral health.

Background

Some of the authors in this study had previously worked together on research into the “memory” of the immune system. They found that the immune system is capable of memorizing past threats, which helps it to become more responsive to new threats [1].

A trained and responsive immune system is mainly a positive thing. However, this isn’t always the case, as the immune system can sometimes misinterpret supposed threats.

The researchers focused on gum disease in this study. Gum disease is one of the most common dental disorders, with research finding that 47.2% of adults aged 30 and over in the United States have some form of gum disease [2].

Therefore, any research into gum disease can be very useful. A common problem with gum disease is that most people do not realize the impact that gum disease has on our physical health.

The Research

The research was completed by researchers at the University of Pennsylvania’s School of Dental Medicine. Their findings were then published in the journal Cell [3].

The research sought to find out the impact gum disease has on the immune system in terms of future interactions with inflammatory-based conditions.

At first, the researchers exposed a mouse to gum disease. Within a week, some of the cells in the mouse expanded in the bone marrow [3].

The researchers found that the immune system of the mouse was capable of handling the periodontal disease [3]. Therefore, there were limited changes in the cells initially.

However, the researchers soon found that the cells appeared to have memorized the inflammation they were exposed to [3]. Therefore, the researchers found that when triggered by inflammation in the future, the immune system would react differently.

The mouse that was exposed to gum disease then had some cells transplanted to mice that had never previously been exposed to gum disease [3]. A few months later, the mice were exposed to collagen antibodies – which triggered arthritis. Arthritis is also associated with inflammation.

To act as a control, cell transplants were also conducted between mice without any form of gum disease and a group of separate mice [3]. This would allow the researchers to compare findings.

The researchers found that the mice that received the cells from mice with gum disease developed more severe arthritis when compared to mice that received cells from mice that were free of gum disease [3].

Overall, the researchers said that this showed the link between inflammatory conditions. The idea was that this study essentially replicated a bone marrow transplant [3]. The mouse with gum disease acted as a donor, with the healthy mice being the recipient.

The researchers were able to conclude that the mice that received a transplant from the group of mice with gum disease were predisposed to more severe arthritis [3].

Impact on dentistry

This research shows the impact that oral health can have on physical health. If these findings were applied to humans – it would show that those with gum disease are vulnerable to severe arthritis. Furthermore, they would also put those receiving a bone marrow transplant from them at heightened risk of inflammatory conditions.

Professor George Hajishengallis, one of the researchers, talked about the impact of these findings on dentistry. “I’m proud for the field of dentistry that this work, with significance to a wide range of medical conditions, began by investigating oral health”, Hajishengallis said [4].

The researchers also spoke of the wider impact these findings may have. They noted that their conclusions could result in a reconsideration of how bone marrow donors should be selected in the future [4]. The conclusions suggest that some bone marrow donors may unwittingly place their recipient at higher risk of inflammatory disorders.

Thinking points…

1) So many of us suffer from gum disease. As this research shows, gum disease does have a big impact on physical health. Treatments are available though for gum disease – including scaling and root planing. If you do have gum disease, it may be worth discussing treatment options with your dentist at your check-up. Consider booking an appointment today!

2) While you may not think you are at risk of gum disease, the truth is that we all are. A common theme in the news is that gum disease has a big impact on physical health. Therefore, if possible, preventing gum disease is crucial. The easiest way to do this is to have excellent oral hygiene, and attend regular dental check ups. We would recommend booking an appointment now!

Research has shown that certain foods result in types of bacteria in our mouths that are known to contribute to tooth decay and gum disease. These foods are those with a high sugar and high glycemic level. Moreover, as well as impacting oral health, they also impact our physical health. The results of this research reaffirm the importance of eating healthily and having excellent oral hygiene.

Recent research has looked into the impact that the foods we eat have on the bacteria in our mouths. The collective group of bacterium in our mouths is called the oral microbiome.

Moreover, the research has then considered how the oral microbiome affects our overall health. This includes both oral health and our wider physical health.

The study focused on the impact that sugary foods have. It is already known that such foods are linked to tooth decay. However, the researchers sought to investigate in further detail.

Background

Bacteria inevitably gets into our mouths. Every time we eat, chew, drink or even bite a nail, bacteria enters. In fact, over 700 types of bacteria have been identified in the oral cavity, with humans typically having over 50 types in their mouths at any one time [1].

But not all bacteria is necessarily bad. However, many types of bacteria can be damaging, and are often linked to tooth decay and gum disease.

It is already known that bacteria can also have some physical health consequences. For example, a recent study found that some types of oral bacteria can be linked to hypertension problems in later life [2].

The research focuses on sugary foods and high glycemic foods. The Glycemic index is a system that shows the rates that different foods are broken down in the body [3].

Foods that are high in the glycemic index cause a rapid increase in blood sugar. Therefore, these foods can be considered unhealthy. For example, high glycemic foods include sweets, doughnuts, soft drinks, baked goods and white bread among others [3].

The research

The research was conducted by scientists from the University at Buffalo. Subsequently, their findings were published in the Scientific Reports journal [4].

The researchers sought to investigate whether carbohydrates and sugar were associated with certain oral bacteria. They used a sample of 1,204 women. The data used came courtesy of the Women’s Health Initiative [4].

Samples from the women were taken. These samples were taken from subgingival plaque – which is bacteria that occurs under the gums. This is important, as this is the bacteria that isn’t visible, and is often neglected [4].

Most studies use saliva as a sample. But by using subgingival plaque, the researchers would get a clearer picture of what was causing gum issues [4].

The researchers also analyzed eating habits, and then cross-referenced these habits with the types of bacteria found in the samples. Therefore, this allowed the researchers to get an overall picture of the impact that certain foods had.

The results showed that a higher intake of sugary and high glycemic foods appears to influence oral health. Furthermore, the authors also suggested that these foods appear to have a long-term impact on health outcomes in older women [4].

Overall, the researchers concluded that a bacteria named Strteptoccus mutans – which is known to contribute to tooth decay and cardiovascular disease – was present strongly in those with poor diets [4].

Moreover, the researchers also found a type of bacteria called leptotrichia, which has been associated with gingivitis – a form of gum disease – in the past [4].

Other types of bacteria that hadn’t previously been thought to contribute to oral health problems were also found. However, the researchers suggested these types of bacteria may now need further research [4].

What this means

The researchers were able to show how eating certain types of food impacted the oral microbiome. There are clearly consequences for oral health and overall physical health.

Therefore, these results emphasize the importance of having excellent oral hygiene and trying to eat healthily wherever possible. After all, we all want to avoid harmful bacteria in our mouth.

Amy Millen, Associate Professor at the University at Buffalo’s School of Public Health and Health Professions, commented on the findings of the team [5]. Millen said that the researchers placed specific emphasis on glycemic foods, as this was “not well studied in relation to the oral microbiome” [5].

Millen also said that “as more studies are conducted looking at the oral microbiome”, that the researchers could infer more “about how diet relates to the oral microbiome and periodontal disease” [5]. Such findings can be very helpful in trying to help improve oral health.

Thinking points…

1) The research above shows the potential damage of sugary foods and high glycemic foods. Now take a look at your diet – do you consume foods like this? If so, try and cut down wherever possible! Because of the damage it can do, it places emphasis on the need to attend regular check-ups at your dentist. Therefore, we recommend that you book an appointment now!

2) Remember that oral health problems are avoidable. It is important to have excellent oral hygiene. Part of this is to ensure that you attend your dental clinic for a check-up at least twice a year. Then if you do have any problems, they can be easily addressed and acted upon. Consider attending your dentist soon, as this is the best way of caring for your oral health.

The Canadian Dental Association (CDA) has released a statement in response to the Federal Government’s proposed federal dental program. This landmark program is expected to improve dental access for millions of Canadians. Therefore, the CDA has welcomed the announcement. They aim to work with the Federal Government over the coming years as part of the program.

The Canadian Dental Association (CDA) has responded to the Canadian Federal Government’s announcement of a proposed new federal dental program.

The CDA released a statement, where they reacted positively to the news. However, they did voice a degree of concern over fears that recent progress that has been made could be slowed down.

The dental program aims to increase dental coverage for millions of Canadians considered to have a low income. The dental program should be beneficial for millions of people around Canada.

About the proposed federal dental program

The federal dental program was announced by the Liberal Party. They reached an agreement with the NDP, as part of a wider confidence-and-supply agreement between the two parties, designed to keep the Liberal Party in power until 2025 [1].

The program would be for families with an income of less than $90,000 annually [1]. The program aims to involve both preventative and restorative services. For example, this would include routine examinations and cavity fillings.

Currently, the dental program is planned to begin later in 2022, before two further phases will take place [1]. The full rollout is expected in 2025.

The CDA’s response

The CDA responded to the agreement in a positive way. They said at the outset of their statement that “all Canadians have a right to good oral health” [2].

Moreover, they note that they have always supported efforts to improve access to oral healthcare for all, with particular focus on those from certain demographics or groups, including seniors, those with disabilities, indigenous people and low-income families [2].

The CDA mention the need to “invest in, and enhance, existing provincial and territorial dental programs” [2]. This refers to existing efforts, and how the Federal Government can’t afford to get complacent with current programs.

They suggest that such efforts are the “single best way” to improve oral health and access to healthcare [2]. However, the CDA also state that such programs are underfunded.

Therefore, the CDA have said that the Federal Government’s dental program left them “surprised” [2]. It appears that the history of dental programs being underfunded has resulted in surprise and concern from the CDA as to whether or not this program will be a success.

The CDA finished their statement by stating that they are looking forward to “collaborating closely with the Federal Government as it works to address the oral health needs of Canadians” [2].

The bigger picture

The CDA have certainly responded in a positive manner. However, they have also promoted caution, mainly due to concerns over past problems with dental programs.

The CDA will hope that this dental program doesn’t stunt the progress that has been made with dental coverage in recent years. Instead, they will hope that it complements it.

Dental coverage is an issue that continues to affect many people. Past research has found that in a 12-month period, just 75% of Canadians visited a dentist, with 23% being put off from visiting due to the cost [3]. This represents a sizeable amount of people who do not get dental check-ups.

Overall, this is positive news for many Canadians. Everyone deserves oral healthcare, and this plan should help millions more people receive much-needed help.

Thinking points…

1) The CDA have consistently promoted improved access to dental care. Another key area that they emphasize is the importance of attending regular dental check-ups. This is an important part of maintaining strong oral hygiene. We recommend having a check-up at least twice a year. Consider booking one now!

2) What do you think of the agreement on improved dental coverage? Are you pleased with it? If you can pinpoint anyone that might benefit from it, encourage them to attend a dental check up soon, rather than wait, as early detection of problems are important. This can also get them into good habits going forward.
