The COVID connection: how leaving gum disease untreated may increase your risk of COVID-19 complications

Gum disease, also known as periodontal disease, encompasses  gingivitis and periodontitis. It is a bacterial infection involving the gums and often the bone that surrounds your teeth. Gum diseases can affect just one tooth or many teeth.


In this article, Dr Neesha Patel, a leading consultant periodontist practicing at Pure Periodontics in London, explains more about gum disease and its newly found connection with COVID-19, as well as how you can safeguard against the virus and keep your periodontal health under control!




How common is gum disease?

Gum disease  is a chronic inflammatory disease that damages the soft tissue and bone supporting your teeth. It is estimated that around  50 per cent of the population suffer from a mild or moderate form of the disease, while 10% are believed to have a severe form.


It is one of the most prevalent non-communicable diseases, but if it’s diagnosed and treated promptly and you maintain proper oral hygiene, the damage caused by periodontitis can be stopped! Periodontitis is the sixth most common condition affecting humanity and has long been linked with respiratory diseases, cardiovascular diseases, diabetes, rheumatoid arthritis, and even premature mortality.


How is gum disease linked to COVID-19?

Gum disease is currently under research with regards to its connection to COVID-19. In its moderate to severe forms, the disease has been identified as placing patients with COVID-19 at a much higher risk of COVID complications. Specifically, there has been a link shown between patients with pre-existing periodontitis and the increased risk of ICU admission, the need for assisted ventilation and ultimately, the death of patients who also acquire COVID-19.


A recent study has shown that more than 80% of all patients who had COVID complications had periodontitis compared to just 43% of those without COVID complications.


While continued research needs to be conducted to assess exactly how significant the correlation is between these diseases, the initial findings demonstrate an extraordinarily compelling link between periodontitis and COVID-19.


Where are we with COVID-19?

Since China reported its first cases to the World Health Organization in December of 2019, COVID-19 has been reported in 219 countries and territories. So far, 108.5 million cases have been reported and there have been 2.4 million deaths so far*. There is no disputing that COVID’s impact is on a global scale.


COVID-19 shows no sign of going anywhere soon. The new variants have emerged and are rapidly spreading. Whilst we have become better at adapting to it by wearing masks, following social distancing and frequent hand-washing, it has altered the lives of all of us, forcing us to change how we go about our regular day-to-day activities.


How can you look after your health?

In the UK, we have all been trying to implement positive and proactive practices. While we wait to receive our COVID-19 vaccines, it is important to pay closer attention to your stress and anxiety levels, as when elevated for prolonged periods they are known to weaken the immune system.


Many people have also become more proactive with their nutritional nourishment and where possible, choosing nutrient and vitamin-rich foods and daily supplements or multi-vitamins to boost immunity. But what about your periodontal health? And how can you improve it?
