Objective: In this article, the potential oral health consequences of vaping are described. While most dentists are likely aware of the potential serious health effects involved with vaping, the aim of this article was to raise awareness on identified oral health consequences. Clinical considerations:Three patients presented to one dental practice with unusual patterns of dental caries, and all three admitted to regular vaping. Vaping components include propylene glycol, glycerin, nicotine, and flavors, which contain sucrose, sucralose, and ethyl maltol. The vapor produced by vaping devices is thick and viscous and much of it is retained on oral tissues. There are over 10 000 different vaping liquids, including some that contain tetrahydrocannabinol (THC) and vitamin E acetate. Vaping clearly has the potential to negatively affect general health, periodontal health, and accelerate the development of caries. There is also evidence that teenagers are being attracted to vaping in astonishing numbers. Conclusions:The general health consequences of vaping have received considerable attention in the national media. There is much to be learned about the consequences of this behavior. There are also potential serious oral health consequences to vaping.It is likely that the composition of certain vaping solutions may make them more harmful than others Clinical significance: It is important that dental professionals are made aware of the potential problems related to vaping. Initial reports show that the effect of ecigarettes on periodontal tissues is similar to that of conventional cigarettes. Some vaping formulations may be highly cariogenic, especially those with sweet flavors, which are used to attract young people. Patients should be routinely questioned about their vaping habits in the medical-dental history. K E Y W O R D Scarrier, dental caries, nicotine, THC, vaping, vaping solution, viscous aerosol
