Smoking, Vaping, and the Oral Cavity-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 dentists’ role in preventing lifelong dental avoidance. He explains that tobacco is the plant, while nicotine is extracted or synthesized; cigarettes contain the whole processed plant plus additives, and combustion generates over 7,000 chemicals, many harmful and carcinogenic.<br /><br />Vapes use a battery, cartridge, and atomizer to heat e-liquid—typically propylene glycol, vegetable glycerin, flavorings, and nicotine. Nicotine’s stimulant effects (dopamine-driven mood changes, focus) also raise heart rate and can cause anxiety and dry mouth; nicotine salts deliver a smoother, faster “hit.” Vaping can produce toxic compounds such as formaldehyde and acetaldehyde from heated solvents, and heavy metals from device coils.<br /><br />Long-term vaping harms are still unclear, but early evidence shows similar DNA damage to oral epithelium as cigarettes. Youth cigarette use has declined markedly, while vaping remains a concern. Teens who vape are about 3.5 times more likely to start smoking. Ongoing vaping is most associated with stress/anxiety relief, “buzz,” and social factors, aided by concealable devices.<br /><br />Orally, vaping is linked to increased periodontal inflammation (dose-dependent bleeding on probing) and higher caries risk via reduced protective enzymes, increased bacterial adhesion/biofilm, and enamel-softening flavor esters. Clinically, providers may see staining/calculus, black hairy tongue, nicotine stomatitis, and concerning lesions like leukoplakia requiring biopsy.
