Some toothpastes can neutralize Covid-19 Some toothpastes can neutralize Covid-19 15 de diciembre de 2020, 0:14 London, Dec 15 (Prensa Latina) A scientific study reveals that some toothpastes that include zinc or stannous fluoride and mouthwash formulas can neutralize SARS-CoV-2 by 99.9% in two minutes. In the second case, these hygienic items must be made with cetylpyridinium chloride to eliminate the novel coronavirus in 30 seconds, the Dental Tribune magazine states. Researchers suggest that some toothpastes and mouthwash formulas can help slowing the spread of the virus by reducing temporarily the amount of the virus in the mouth. In addition, scientists believe that due to the comparable amounts of the virus not only in saliva, but also nose and throat, reducing the virus in the mouth could help prevent spread during the time that oral care products are active.
