Use of mouthwashes against COVID-19 in dentistry

Updated: Sep 26, 2021

Antiseptic mouthwashes have been widely used as a standard measure before routine dental treatment, especially preoperatively.

They have an essential role in reducing the number of microorganisms in the oral cavity. Recent publications have suggested that rinsing the oral cavity may control and reduce the risk of transmission of SARS-CoV-2.

Pathogenesis of coronavirus disease 2019

Coronaviruses are a group of enveloped RNA viruses that present a typical structure with the “spike protein” in its membrane envelope. A high SARS-CoV-2 viral load has also been detected in saliva, and it its presence has even been suggested in periodontal pockets. These findings agree with previous investigations that have suggested that virus transmission can be closely connected with saliva interactions making oral tissues a possible reservoir from which SARS-CoV-2 transmission may occur during coughing,

sneezing, talking, and even during dental care.

Oral antiseptics used against viral infections

Mouthwashes are widely used solutions for rinsing the mouth, especially before oral surgery, due to their ability to reduce the number of microorganisms in the oral cavity and colony-forming units in dental aerosols. The American Dental Association and the Center for Disease Control and Prevention have recommended the use of preprocedural

mouthwashes before oral procedures.

Hydrogen peroxide (H 2 O 2 )

Since SARS-CoV2 is vulnerable to oxidation, preprocedural mouthrinses containing

oxidative agents such as 1% H 2 O 2  have been suggested to reduce the salivary viral load.


we suggest the use of preprocedural mouthwashes in dental practice to reduce SARS-

CoV-2 viral load from previous dental procedures and to reduce the cross-infection risk

while treating patients during the pandemic.
