COVID-19 Effects On Your Mouth

Updated: Jun 22

"During the pandemic, high-risk patients have tended to develop more than one problem, often exhibiting three or four at the same time because too much time has gone by without a dental check-up. Problems typically include carious lesions and periodontal disease.”

Your oral health and your general health are related so much. Over the past three years, many health professionals have wondered about the effects that COVID-19 has had on dental health.

Early findings have shown that Covid can affect blood flow, which can explain why some patients end up with discoloured “Covid teeth.” Some are finding that their enamel becomes thinner or breaks down completely. To prevent further damage to your teeth, ensure you get regular dental checkups and keep up with routine flossing and brushing.

Some of these effects haven’t been apparent until people have undergone dental procedures or seen a dentist for other reasons.


Be aware of any changes in your teeth after contracting COVID-19, especially sudden changes that may indicate an infection. If you’re experiencing any dental problems after COVID-19, don’t wait to see your dentist. Treatment is typically more manageable the sooner you’re evaluated by a dentist. Therefore, here are some of the effects on teeth and oral health that people have suffered after contracting Covid-19.

  • Discolouring - The teeth are often discoloured (turned grey, green, or very black), and the enamel becomes thinner or breaks down completely. There are also cases of black sludge in people’s mouths, which is caused by an acid reaction from the bacteria present in COVID-19.

  • Dental pain - Some people have developed toothaches, dental pain, and even bad breath after contracting COVID-19. These symptoms can be a sign that an infection is developing in the mouth. Covid teeth pain is one of the first signs people experience.

  • Cavities - Interestingly, some research has shown that cavities can be an entry point for the Covid-19 virus. Also, because Covid-19 weakens people’s teeth, they are more susceptible to tooth decay and cavities once people have been infected. This side effect is one of the more common issues with dental health after contracting COVID-19. The bacteria that live in our mouths affect teeth even if an individual does not have Covid-19 symptoms.

  • Tooth and gum sensitivity - Covid teeth have caused a heightened form of tooth and gum sensitivity in some patients. The good news is that tooth sensitivity is often short-term. Your front teeth may be sensitive to very hot or cold foods and drinks for a few months, but this shouldn’t last forever. To reduce sensitivity, use a straw when drinking and chew sugar-free gum regularly. If the pain becomes too much to bear, talk to your dentist.

  • Tooth Loss - Other people have reported that their teeth fall out after contracting COVID-19. While it’s infrequent that people’s teeth simply fall out of their sockets, this has been reported by some Covid patients. While Covid is unlikely the loan cause of this, it may be compounding existing oral health issues.

If you notice pain in your teeth after contracting COVID-19, don’t ignore it. Even if the pain isn’t constant or severe, it can lead to infections that indicate that your teeth are shifting and beginning to fit uncomfortably in your mouth.


How to Care for Your Teeth and Gums

Here are some expert tips for healthy teeth and healthy gums.

  • Brush twice a day, especially before going to bed. Many adults remember to brush in the morning, but it’s most important to brush your teeth before sleeping. Long sleeping periods give time for more plaque and germs to accumulate.

  • Remember to brush your tongue. Your tongue collects the same bacteria that your teeth do, which can lead to tongue infection and bad breath. Remember to brush your tongue softly every time you brush your teeth.

  • Floss your gums. Flossing is an important part of keeping healthy gums, and you should floss at least once a day. Flossing after a long time can cause your gums to bleed slightly, but it will stop eventually.

  • Eat healthily. Healthy food with fibre and vitamins is good for your teeth and can remove plaque. In contrast, foods high in acids or sugar can cause tooth enamel to break down, leading to tooth decay.

  • See a dentist twice a year. Dental checkups are like car engine checkups – they can prevent costly problems if you follow a regular schedule. We recommend seeing a dentist at least once every six months.
