Adolescent Smoking, Vaping, and the Oral Cavity-Adolescent Smoking, Vaping, and the Oral Cavity

Video Transcription

Video Summary

A speaker addresses pediatric dentists about smoking and vaping’s effects on the oral cavity, emphasizing the profession’s role in helping children grow up unafraid of dental care. He explains tobacco versus nicotine: tobacco is the plant, while nicotine is extracted or synthesized; cigarettes contain the whole plant plus thousands of combustion-generated chemicals. Vapes deliver nicotine through e-liquids typically made of propylene glycol, vegetable glycerin, flavorings, and nicotine, heated by coils. Nicotine salts can create a smoother, faster “hit,” increasing addiction risk.<br /><br />He notes vaping aerosols may contain carcinogens and toxicants such as formaldehyde, acetaldehyde, and heavy metals from device components, but long-term outcomes (e.g., cancer rates) remain uncertain due to limited study duration. Early evidence suggests similar DNA damage in oral epithelium from vaping and smoking.<br /><br />Teen use patterns show declining cigarette smoking and more recent vaping trends that are stable or decreasing. Teens often try vaping from curiosity or friends, but continued use is more linked to mood regulation, stress relief, or the “buzz,” with social factors (cloud tricks, concealability, customization) also important. Evidence suggests vaping increases the odds of later cigarette smoking (odds ratio ~3.5).<br /><br />Orally, vaping is associated with increased gingival inflammation/periodontitis and higher caries risk through reduced protective enzymes, increased bacterial adhesion/biofilm, xerostomia, and possible enamel softening from flavor esters. Other findings include staining/calculus, black hairy tongue, nicotine stomatitis (reversible), and leukoplakia (biopsy needed). Synthetic vs extracted nicotine risks are unknown.
