The increasing popularity of vaping has introduced new concerns for both dental professionals and public health experts. Electronic cigarettes were originally promoted as a safer alternative to traditional tobacco products, but their use, especially among adolescents and young adults, has grown rapidly. While much of the public discussion around vaping focuses on lung health, research is beginning to show that vaping can
also have harmful effects on the oral cavity. As vaping becomes more common, understanding its impact on oral health is important for prevention, patient education, and long-term health outcomes.
Vaping exposes the mouth to aerosols that contain nicotine, flavoring chemicals, and other substances that can negatively affect oral tissues. Nicotine causes reduced blood flow to the gums, which can impair the body’s ability to fight infection and heal properly. Studies have found that individuals who vape may experience increased gum inflammation, bleeding, and early signs of periodontal disease, even if they do not smoke traditional cigarettes (Irusa et al., 2020). Because these changes can develop gradually, many users may not realize the damage vaping is causing to their oral health.
In addition to its effects on the gums, vaping may alter the balance of bacteria in the mouth. Research suggests that e-cigarette aerosols can disrupt the oral microbiome, encouraging the growth of harmful bacteria associated with cavities and periodontal disease. Ingredients commonly found in vaping liquids, such as propylene glycol and glycerin, can contribute to dry mouth by reducing saliva production. Since saliva plays a critical role in protecting teeth and neutralizing acids, decreased saliva can increase the risk of tooth decay and oral infections over time (Pushalkar et al., 2020).
The rise of vaping among adolescents and young adults is particularly concerning from a dental perspective. Many young users have never smoked traditional cigarettes, yet they may begin to experience oral health problems at an earlier age than expected. Early exposure to nicotine can also increase the likelihood of long-term addiction, making cessation more difficult. Dental professionals may begin to see signs such as gum irritation, dry mouth, or increased caries risk in patients who otherwise appear healthy, raising concerns about the long-term oral health consequences for this population (Centers for Disease Control and Prevention, 2023).
Despite growing evidence of harm, many people continue to believe that vaping is largely harmless. Dental visits may be one of the few opportunities for healthcare providers to discuss vaping habits with patients and explain potential oral health risks. Dentists and dental hygienists are well positioned to identify signs of vaping-related damage, educate patients, and offer guidance on quitting. Including questions about vaping use as part of routine dental assessments may help promote early intervention and prevention.
From a public health standpoint, the rise of vaping presents new challenges for oral health education and policy. Prevention efforts such as school-based education programs, public awareness campaigns, and restrictions on flavored vaping products have been proposed to reduce youth use. Continued research is needed to better understand the long-term effects of vaping on oral health and to inform evidence-based
public health strategies.
Overall, vaping represents a growing concern for oral health that is often underestimated. While it is commonly viewed as a safer alternative to smoking, evidence suggests that vaping may contribute to gum disease, changes in oral bacteria, and increased risk of dental caries. Recognizing vaping as a dental public health issue is essential for protecting oral health, particularly among younger populations, and for
guiding future prevention efforts.
