E-cigarettes and tobacco heating products cause significantly less staining to teeth than conventional cigarettes, a new study has found.
While cigarette smoke caused significant enamel discolouration, vapour from the e-cigarettes and aerosol from the tobacco heating products caused only minimal staining.
These next generation products do not involve combustion; the vapour and aerosol they produce are less complex and contain significantly lower levels of certain toxicants compared to cigarette smoke.
"Many studies have postulated that it is the tar in cigarette smoke that stains teeth," said Annette Dalrymple, senior scientist at British American Tobacco in the UK.
"The study clearly shows that the e-cigarettes and tobacco heating products assessed caused minimal discolouration -- very promising for consumers. However, further studies are required to understand the long-term effect on teeth staining and oral health when smokers switch to using next generation products," Dalrymple added.
