Although the use of electronic cigarettes or vaping is usually presented as a less harmful alternative to conventional tobacco, dental health specialists are sounding the alarm.
In the United States, approximately between 289.6 and 311.2 million electronic cigarette units were sold in retail stores between 2023 and 2024, according to www.tobaccomonitoring.org. Among their data they also reported that, although unit sales declined slightly in 2024, the market has experienced a massive surge in disposable devices, which now dominate sales that grew more than 500% between 2019 and 2023.
Dr. Vivian Menéndez warns that this habit is far from harmless for the oral cavity, potentially triggering problems ranging from dental aesthetics to serious periodontal diseases.
According to Dr. Menéndez, the composition of the liquids used in these devices is the main risk factor.
“Many devices contain nicotine and chemical substances that can reduce saliva flow, causing dry mouth,” she notes.
The lack of saliva (xerostomia) is not just a passing nuisance; it is a reduced protective barrier for the teeth. Without adequate lubrication, the risk of developing cavities and gum diseases increases exponentially, since saliva is responsible for neutralizing acids and cleaning food particles.
“It is essential to understand that, although vaping contains fewer toxic substances than traditional cigarettes, it is not harmless,” she explains, urging users to undergo periodic check-ups to mitigate these effects.
Does vaping stain teeth? One of the most frequent questions among users is the aesthetic impact. While it is true that stains may be less intense than those caused by the tar of traditional tobacco, Dr. Menéndez clarifies that the risk persists.
“Many vape liquids contain colorants and sugars that directly contribute to dental pigmentation and plaque buildup.”
“How to know if vaping is damaging your mouth? Early detection is key to avoiding irreversible damage. The specialist recommends paying attention to the following symptoms:
1- Gums that bleed: a clear sign of inflammation or infection.
2- Persistent bad breath (halitosis): caused by dryness and bacterial proliferation.
3- Tooth sensitivity: due to enamel wear or gum recession.
4- Bacterial plaque buildup: aided by the sugars present in the vapors.
