Abstract

Introduction

The existence or lack of an association between the use of alcohol-containing mouthwashes and the development of oral squamous cell carcinoma remains a significantly contentious issue within the scientific community. The published literature on the topic includes both epidemiological studies assessing associations on a population level and mechanistic studies investigating the local effects of alcohol-containing mouthwashes in both in vitro and in vivo environments, as well as reviews evaluating, comparing and synthesising these results. Despite a broad base of evidence, there remains no clear academic consensus with regard to the relationship between alcohol-containing mouthwashes and oral squamous cell carcinoma. This review aims to present and evaluate the evidence for and against any association.

Conclusion

While there is a lack of consistent evidence, it is advisable for clinicians to promote the use of non-alcoholic mouthwashes in order to minimise any potential increase in risk, and discourage long-term use of high alcohol-containing products.
