Everybody on the planet knows about COVID19. Yet with each day, come new discoveries about this mysterious disease. For many, experiencing COVID19 is no more severe than catching a cold. But for others, they experience far worse outcomes such as respiratory failure and death.
The risk for contracting a severe form of COVID19 is higher if you have certain medical conditions including cancer, kidney disease, obesity, type 1/2 diabetes, respiratory conditions, high blood pressure and heart disease, as well as being in an advanced age group.
Now, recent new studies reveal that one other health condition may also increase your risk of experiencing severe COVID19 – untreated gum disease and poor oral health.
What is the link between untreated gum disease & COVID19?
German researchers have discovered that when COVID19 patients experienced an inflammatory response leading to respiratory failure, their levels of a pro-inflammatory cytokine called interleukin-6 (IL-6) were elevated.
This is the same cytokine implicated in the phrase “cytokine storm” – a term coined to describe the out-of-control immune response occurring in patients with severe COVID19 and other serious auto-immune disorders.
People with chronic, untreated gum disease (periodontal disease) experience higher levels of IL-6 as a result of the body’s constant inflammatory response to infected gum tissue.
Since elevated levels of IL-6 indicate a strong potential for respiratory complications in COVID19 patients, the authors of the study concluded that treating gum disease and decreasing IL-6 levels may help prevent or reduce severe COVID19 complications.
Earlier British study correlates German findings on IL-6
In June 2020, an English study also found that high IL-6 levels, along with a high oral bacterial load in the mouth, were significant risk factors for severe COVID19 respiratory complications. Their advice: keep good oral hygiene, regular checkups and get gum disease treated!
Treating gum disease to reduce IL-6 levels in the body
The treatment for periodontal disease is quite simple. It is performed by a dentist in a basic dental procedure known as a scale and root planning – a deep dental clean right down to the roots. During this treatment, all oral bacteria are removed above and below the gum line – keeping your teeth and gums healthy.
Once gum disease is being properly managed and treated, the body’s inflammatory response winds down along with lower levels of IL-6.
