For those diagnosed with COVID-19, having inflamed and infected gums may lead to higher rates of complications and fatal outcomes. This is the conclusion of a recent international study conducted by McGill  University. The study, which was published in the Journal of Clinical Periodontology, found a link between gum disease, medically known as periodontal disease, and greater COVID-19 complication risks, including admission to the ICU and death.

The results of the study were based upon examining the records of 568 Qatari patients with severe COVID-19 cases. All of their records were digitized, making it possible to completely gather the data and quickly perform the research. 

Study Findings

Some of the key findings of the study among patients with both COVID-19 and gum disease are: 

  • Intensive care unit admissions were 3.5 times more likely.
  • Need for a ventilator was 4.5 times higher.
  • Fatality rates were 8.8 times more likely.

The McGill University study is the first of its kind to research the combined effects of COVID-19 in those with existing periodontal disease.

One of the leaders of the study, Belinda Nicolau, stressed that the results indicated that good oral health is extremely important in both preventing and managing COVID-19 complications. She expressed that their study highlighted the extremely strong link between periodontal disease and COVID-19 disease outcomes.

What is periodontitis?

Periodontitis is an end-stage periodontal disease. Periodontal disease is a dental condition affecting the gum tissue and bone structures supporting the teeth. It is caused by plaque that creates acids that inflame gum tissue, further leading to a chronic infection.

In its earliest form, periodontal disease is known as gingivitis – a condition that can be prevented or reversed by proper oral care, such as regular brushing and flossing. As gingivitis progresses, it develops into periodontitis. At this stage, the condition is considered to be irreversible, potentially causing teeth to loosen and fall out.

Biomarker Red Flags

Researchers noted a significant increase in biomarkers like C-reactive protein in patients affected by both COVID-19 and gum disease. Biomarkers like these are strong indicators of bodily inflammation.

The researchers behind the study believe that combined levels of inflammation due to both COVID-19 and gum disease may be too much for these patients, leading to increased immune system stress and systemic inflammation. The result of this increased level of inflammation is poor patient outcomes.
