Peppermint for Dental And Oral Health

Research suggests that peppermint-containing mouthwashes have been examined in the context of oral hygiene and, more recently, potential antiviral properties relevant to dental settings. The single available linked study, a laboratory-based experiment rather than a clinical trial, evaluated commercially available mouthwashes against SARS-CoV-2 and found mixed results depending on the active ingredient, with some formulations achieving substantial viral inactivation while others showed little to no effect. Peppermint itself was not isolated as an active variable in this research, making it difficult to draw conclusions specifically about peppermint's contribution to any observed outcomes. Overall, the evidence base here is extremely limited, consisting of one in vitro study, and further clinical research would be needed to draw meaningful conclusions about peppermint's role in dental or oral health applications.
