Viruses, how they spread and how to protect against them, is something we have heard a lot about since COVID-19 became a pandemic. We’ve learned that COVID spreads most easily through the air, and that masks and vaccines are our best protection against infection. We know that the virus tends to become firmly established in the nasal passages, where it can be aspirated into the lungs. How much of the virus that spreads through the body varies from patient to patient, which contributes to some getting much sicker than others.

But if you are exposed to COVID, what if you were able to reduce the amount of virus in your nasal passages before it spread to your lungs, and not only prevent person-to-person spread, but also diminish the severity and length of your illness? If only there were something that reduced the “viral load” that is delivered to your lungs through the nasal passages. Well, there may be.


To keep patients and staff as safe as possible during the pandemic, many dental practices have implemented extra safety precautions. Even before the pandemic started, dentists were already practicing a gold standard level of disease control. Many are now asking patients to use a pre-procedural rinse at the office (usually xylitol or hydrogen peroxide based), and even to use a xylitol-containing gum multiple times a day to help reduce viral loads.

Recent studies are showing promising antiviral properties of xylitol, and we now recommend xylitol nasal spray to our patients. These studies show that it kills the virus, as well as blocks the adhesion of the virus to the nasal membrane, which is how most people get sick from COVID-19 and other viruses.

Xylitol has a long history of being safe and beneficial in preventing bacterial infections, and has now been reported to reduce the severity of viral infections as well.

A 2016 study demonstrated the antiviral properties of polyols such as xylitol on the H1N1 and hRSV viruses, and reported a reduction in the severity of these infections.¹

A recent case series showed that Xlear® Nasal Spray, given its established safety profile and compelling clinical results described here, could be a potential adjunct treatment option in mild-moderate COVID-19 cases.²

Xylitol is already used in a number of dental products, including toothpastes, mouth rinses, dental friendly gums, and mints. Studies are now showing that antiviral nasal sprays containing xylitol, such as Xlear® Nasal Spray, can reduce the amount of viral load in your nose, and therefore potentially decrease the viral load delivered to the lungs.

The early stages of COVID-19 is a very important time to have treatment in order to reduce serious, long-lasting effects. We believe that washing the nose with Xlear® Nasal Spray can be a crucial step in staying healthy and curbing COVID-19’s progression into later stages.
