Electronic smoking device usage is on the rise. Vaping is gaining popularity with younger patients who have never used nicotine products before and are now trying flavored electronic cigarettes.
I recently caught an episode of a popular sitcom in which a teenage daughter candidly admitted to her mom that she had tried a vaping pen. Her mom got very upset, and the daughter had no clue why her mom would be so put off by it. I thought to myself, “What do I know about vaping, and why is this a prime time storyline?” So I began to research, and I discovered that this is a controversial issue both nationally and worldwide. Vaping is gaining popularity, and young people are being exposed to it while not being fully aware of the consequences to their health. A recent study conducted by Monitoring the Future conducted a survey of 44,000 students last year spanning from 8th grade to 12th grade and discovered that the rate in which vaping products were used doubled in one year’s time.1
Times are changing
“In the late 1990s and early 2000s, some states implemented comprehensive smoking bans that prohibited smoking in most workplaces and all public places, including previously exempted bars and restaurants.”2 Cigarette smoking has been decreasing since laws were enacted that banned smoking in public places. Use among middle school and high school students has been steadily decreasing since 2014 due to education about the harmful effects of tobacco. This has left the consumer market wide-open for alternative uses of nicotine. Electronic devices are promoted as a less harmful alternative with fun flavors for recreational and social use.3
In 2019, the FDA took steps to restrict the sales and marketing of electronic smoking devices to minors. “Some people have suggested that use of e-cigarettes by young people might ‘protect’ them from using cigarettes further down the road. There is no evidence to support this claim. Some studies show that nonsmoking youth who use e-cigarettes are more likely to try tobacco cigarettes in the future than nonsmoking youth who do not use e-cigarettes.”4
Vapor lounges, sometimes called vapor houses, are popping up everywhere—in big cities, small towns, shopping malls, strip malls—usually centrally located in heavily trafficked areas. I passed by one vape shop next to a game store and video arcade in my local community, clearly attempting to attract young people. Consumers can purchase their favorite flavors from coffee to maple syrup all while relaxing and vaping in plush lounge chairs indoors. Electronic cigarette users report using energy drinks while vaping. Some vapor liquid contains substances such as caffeine and ginseng for an energy boost or as an alternative to non-nicotine vaping.5,6,7
Risks of vaping
Electronic cigarette users may experience xerostomia and increased risk for tooth decay as a result of the vaporized liquid entering the mouth. Aerosols from vaping irritate the lining of the mucosa and are absorbed into the buccal mucosa and the pharyngeal tissues. According to the British Dental Journal, e-liquids from electronic cigarettes create an aerosolized cariogenic vapor delivered directly to the mucosa and hard tissues of the mouth, bonding with streptococcus mutans. That process, along with a dry environment, creates a perfect breeding ground for a biofilm matrix to bloom.6
Similar to tobacco cigarettes, smoke-free vaping devices have chemicals manufactured into them that cause irreversible damage to the human body. Much research is being conducted on the effects on the oral cavity; however, we must wait for long-term studies that show the vaping effects on epithelial tissue.8
Oral mucosa that is exposed to chemicals will incur changes to the epithelial tissue and promote the inflammatory response in the periodontal ligament resulting in periodontal disease.3,9 Chemicals in the aerosols found in vaping liquid or “juice” include:
- Diacetyl: chemical flavoring that is safe to ingest but unsafe when heated to a high temperature and inhaled; associated with serious lung disease
- Benzene: a volatile organic compound found in car exhaust and linked to leukemia and bone marrow disease
- Heavy metals: levels of lead, nickel, chromium, and manganese exceed safe limits for inhalation
Nicotine: addictive stimulant and potent parasympathomimetic alkaloid10,4,11,12
Nontoxic chemicals found in vaping liquid create palatable pleasure and increase risk for tooth decay. These include:
- Propylene glycol: food additive sweetener13,6
- Glycerin: colorless, odorless, viscous liquid for sweetness13,12
How many of us are comfortable broaching conversations about smokeless nicotine products with our patients? When put on the spot, can we pull out statistics, figures, and share the real truth about vaping? As uncomfortable as it may be, we need to ask our patients about their exposure to and usage of vaping as part of their health history update. Many patients believe that it is safer and less harmful than tobacco cigarettes. The truth is that long-term effects are still unknown. More research needs to be conducted according to the National Institute on Drug Abuse.14
Some patients may be vaping as a form of tobacco smoking cessation. “E-cigarettes haven’t been thoroughly evaluated in scientific studies. For now, not enough data exists on the safety of e-cigarettes, how the health effects compare to traditional cigarettes, and if they are helpful for people trying to quit smoking.”14 Inform patients that one liquid nicotine cartridge contains about 200 puffs, equivalent to the amount of nicotine in one pack of 20 cigarettes.15
I challenge hygienists to screen for vaping usage at both initial and recare appointments. Do soft tissue assessments and document mucosal changes. Utilize CAMBRA for patient education. Clinically, we are going to see an increased rate of decay in vaping patients. It is our duty as oral health-care providers to educate our patients on risk factors along with the effects of using vaping devices as an alternative to smoking cigarettes. Our younger patients are being exposed to vaping and are lured by the attractiveness of advertising. It is gaining popularity recreationally with younger patients including those who have never smoked before. It is our job to bring the facts to our patients.
