Can Mouthwash Stop the Spread of COVID-19?

Ever since the outbreak of COVID-19, people have been spouting rumors left and right on how to prevent or “cure” this new disease. Unfortunately, there is no cure yet. However, there are several precautions you can take to keep yourself from contracting the coronavirus, such as adhering to social distancing measures, wearing masks when you do go out, and washing your hands frequently. You may have heard that rinsing and gargling with mouthwash help get rid of the virus, but is there any truth to that idea? Keep reading to find out.

Can Rinsing with Mouthwash Kill COVID-19?

The answer isn’t actually all that clear-cut. According to this video that the American Dental Association released, there is no significant evidence that rinsing with mouthwash kills the coronavirus. However, they claim that a study in China found a link between using mouthwash and lower rates of COVID-19. It’s worth noting, though, that mouthwash in China has a different chemical makeup than mouthwash here in the United States. Because of this, rinsing with Chinese mouthwash may affect the coronavirus, but the same can’t be definitively said for American mouthwash.

Should You Still Use Mouthwash Anyway?

Yes! Although brushing and flossing are excellent ways of keeping your teeth and gums clean, these actions only clean a portion of the soft tissues in your mouth. As a result, bacteria that form on these soft tissues can re-deposit back onto your teeth and gums, contributing to oral health problems like gum disease and tooth decay.

However, keep in mind that not all mouthwashes are the same. The mouthwash you select may vary based on your individual oral health needs. For example, if you have a history of gum disease, you might want to invest in a mouthwash that fights plaque. Some mouthwashes contain fluoride to boost the strength of your enamel. Some contain chemicals that whiten your teeth.

One thing to remember, though, is to NEVER use a mouthwash that contains alcohol. This is because alcohol actually contributes to dry mouth, a condition in which you don’t have enough saliva. Without saliva, excess food particles don’t get rinsed away, so they can attract bacteria that cause cavities.

Even though mouthwash doesn’t necessarily kill the coronavirus, you should still use it since it benefits your oral health. If you’re not sure which type of mouthwash is best for you, then ask your dentist.
