In March 2020, shortly after the global shutdown due to the COVID-19 pandemic, the National Dental Association invited me to write a white paper exploring the role of oral rinses (mouthwash) in reducing the viral load in the mouth. My report was published in April 2020, shortly before dental practices reopened in the United States.
Here is the abstract:
The benefits of pre-rinsing prior to dental procedures have been promoted by clinical and industry studies. (Molinari ,1992), (“Pre-Rinsing A Must for the Dental Professional,” 2018) However, the practice has still not been widely adopted by most oral health and medical providers. In light of the novel coronavirus (2019-nCoV) pandemic, dental professionals must consider regular pre-rinsing as a potentially effective method of significantly reducing the viral load in the oral cavity. In this brief, we report on the efficacy of antimicrobial mouth rinses that may be particularly effective against viruses.
