The mouth plays a critical role in the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) owing to the fact that both the tongue and salivary glands are conducive environments for the storage and spread of the virus. This case series aimed to describe the oral manifestations of coronavirus disease (COVID-19) and report the rapid response to Phtalox® treatment in all patients who tested positive for the virus. The patients were grouped based on whether according to convenience as soon as they tested positive for COVID-19. All patients had mouth ulcers and were advised to use 5 mL of Phtalox® mouthwash for 1 min, five times daily, in addition to standard COVID-19 treatment. Complete healing of mouth ulcers occurred in all patients diagnosed with COVID-19, and the mean duration for complete healing was 2.37 days. General improvement of COVID-19 symptoms was also observed. Based on the rapid recovery of mouth ulcers observed, we suggest that Phtalox® is effective as a complementary oral treatment for ulcers associated with COVID-19.
