Current thinking about the effects of e-cigarettes on oral cancer risk.

Abstract

In the last decade there has been a significant increase in the appeal and popularity of e-cigarettes. Recent national news headlines outline that one million smokers will be given a free vaping starter kit to encourage them to give up tobacco products. An independent report commissioned by the UK Government has cited promotion of vaping as a critical recommendation to ensuring England is smoke-free by 2030. Undoubtedly, the dental team will now encounter many more questions from patients keen to know more regarding the safety of electronic nicotine delivery systems and their effects on the oral cavity. However, it is often difficult to answer these questions due to a lack of evidence regarding their impact. Although there are some preliminary animal and in vitro data, additional well-designed, long-term studies are required to investigate oral health outcomes of e-cigarette use.We aim to summarise the latest evidence to better inform clinicians about the effects of vaping on oral health, particularly regarding the risks of oral cancer, so they can better inform their patients.
