How Periodontal Disease Makes COVID-19 Worse

Aging with a Vengeance is more than gaining muscle mass and losing fat around your waist; it also means that your immune system is robust. I think we often over-emphasize supplementation; while I think it’s necessary, it really should serve as support for other actions that are equally or even more important. For example, taking care of your teeth. By that, I mean regular checkups, brushing after meals, and flossing every day. Does that affect the immune system? You bet it does, and a recent study illustrates how significant that can be.

Researchers in Qatar conducted a study to see if people with periodontal disease had an increased risk of being in the intensive care unit (ICU), being put on a ventilator, or dying from COVID-19. Qatar Is a country of 2.3 million people with an advanced electronic medical records system; because dental records are a part of the medical records system, they were able to identify people with periodontal disease, sometimes called gum disease. In addition to the medical records on COVID-19 and how the subjects fared, they were also able to get data such as BMI, HbA1c, and CRP, among other health indicators.

As an observational study, researchers were able to find 568 people who were diagnosed with COVID-19 between February 2020 and the end of July. That number included 40 people with severe cases of COVID-19 that required hospitalization. The characteristics of those who had severe cases are similar to what we find in the U.S.: more were overweight or obese, had higher HbA1c levels, and had higher CRP levels.

Of those who had periodontal disease, 33 had severe cases of COVID-19; only seven people who had no periodontal disease had a severe outcome. When looking at the odds ratios, a person with periodontal disease had six times the risk of being admitted to the ICU, almost eight times the risk of being put on an ventilator, and a 17 times greater risk of death from COVID-19.

Why would having periodontal disease, an infection that appears to be limited to the teeth and gums, have such an overall effect? The reason is that it creates a state of higher inflammation that compromises the immune system. When exposed to the virus, the immune system is already stressed and the body does not have all the resources it needs to fight the infection.

The Bottom Line

Here’s my advice: if you’re overdue for your dental checkup, call and make the appointment, especially if your gums bleed regularly when you floss, if your gums seem inflamed, or if you have a very bad mouth odor. No excuses; gum disease should not be ignored.

I see many comments in social media about “all the talk being about vaccinations, masks, and social distancing.” “No one ever talks about diet and exercise, etc.” The reason, at least in my humble opinion, is that the last 50 years have clearly demonstrated that most people in the U.S. don’t eat well, don’t move enough, and eat more than they should.

Instead of criticizing people for their poor dietary and exercise habits, the current medical approach seems to be to meet people where they are. My hope is that by addressing some of the other issues related to health, such as periodontal disease and overall healthcare in our quest to age with a vengeance, all readers will see ways to make their immune system much more robust so it can do a better job of protecting them.

And if it has the side benefit of shutting up the naysayers that talk about long-term solutions only at the exclusion of the things that we know are working right now—such as vaccinations, masks, etc.—I’m good with that. As I said in May, not fear; respect.

Investigating the Architecture of Cavities

Have you ever wondered how your kids get cavities or why you got them as a kid? As I was researching studies on the microbiome, I found a fascinating article on cavities.

Cavities, also called dental caries, are a disease caused by bacteria that attack the biofilm known as plaque and damage the enamel of the teeth by creating an acidic atmosphere. In addition to the bacteria, cavities are also dependent on diet. All that stuff about sugar causing tooth decay? Yes, it’s actually true—just maybe not in the way we thought. The primary bacterium associated with tooth decay is Streptococcus mutans, an aggressive plaque builder and acid-producer. But how?

Researchers from two universities wanted to examine any types of structures that might be built on teeth by S. mutans and other bacteria that might contribute to cavities. What kind of structures are we talking about? No one really knew for sure. But to find out, they needed to study the structures as close to the mouth as possible but not actually in the mouths of children; they used the extracted teeth of children who had so much decay the teeth couldn’t be saved and preserved them for analysis. As unbelievable as it may sound, up to 2.5 billion people, mostly children, are impacted by this type of decay.

We’ll continue this look at the topic on Saturday.

Schedule Your Dental Exam

While your physician may examine your tonsils and tongue when you have your physical, that doesn’t include your teeth. For that, you need to see a dentist. Asking people to visit a dentist is right up there with the fear of public speaking—so many people just hate it. We’ve got a great dental team that takes care of our teeth and they do everything they can to make the visit a pleasure, so Paula and I don’t mind going. Find a dentist that works with you, and the only way to do that is by trial . . .
