The company removed the claims in question after receiving the warning letter from the U.S. Food and Drug Administration.
In a letter dated Nov. 18, the U.S. Food and Drug Administration (FDA) issued a formal warning to OraCare related to the company's website including claims that its OraCare Health Rinse and OraCare Operatory Pre-Rinsing Set can "mitigate, prevent, treat, diagnose, or cure COVID-19."
The letter cited two specific pages on the OraCare website where the site mentioned studies showing the products were effective at killing human coronaviruses. As of the time of publishing this news both pages and the claims in question had been removed from the website.
While the claims were removed as they were not approved by the FDA at this time, OraCare has been active with research into how its activated chlorine dioxide rinse can kill bacteria, viruses, and fungi, and a page citing research in this area is still active on the OraCare website.
